Sun was soon rising and temperature was nearly minus 20 degree centigrade. I had my morning walk with my camera in the Sörnäinen district, quite close to downtown Helsinki. The cover photograph of this issue is from that moment. The CHP power plant of Hanasaari was running with full capacity. The fuel it used was coal. The peak load district heating power plant near by it was also in use. It burns heavy oil. tiful view. From the environmental point of view, it was not a very beauPolitically, the fuel is a difficult question in Helsinki, where the municipal power company is Helsingin Energia. The target of the company for the coming years includes a significant increase in renewable energy and carbon neutral energy production by 2050. The year 2050 is far from this moment and the fuel question is very difficult. The political decision-makers in Helsinki have in their hands a development programme package which outlines the plan to make the transition from coal to wood-based fuels in future. In Hanasaari, this means change from coal to pellets or other biomass. The black coal storages will be transformed into white wood fuel mountains. Energy efficiency is also a key question in municipal energy production and distribution. In Helsinki, efficiency is needed on many fronts, in both consumption and production. Helsingin Energia has been doing a good job trying to build better, efficient and environmentally friendly solutions in the challenging situation in the arctic city. This has been noted also internationally. Helsingin Energia has been awarded also a Fair District Heating Quality Label. The Fair District Heating Quality Label has been designed to increase the transparency and openness of energy and district heating company operations. *** After the morning walk, I go to my warm home. I had pragmatic thoughts about the question of fuel: still feeling the frost in my bones, I was ready to accept coal and heavy oil fuels. And at least we are trying to build a better future in my Nordic home city. RISTO VALKEAPÄÄ EDITOR-IN-CHIEF

Keljonlahti CHP plant in Jyväskylä celebrates its first anniversary In Central Finland, the Keljonlahti power plant in Jyväskylä is about to complete its first year of commercial power production. According to the operators, Keljonlahti CHP plant’s performance has been up to expectations throughout the harsh winter period. 6 enertec 2011

Photos: Jyväskylän Energia / Nordic Airfotocenter Ltd T here were several reasons why Jyväskylä Energy wanted to build a new combined heat and power (CHP) plant that co-produces electricity and district heating power in the same process. For one thing, there was an increasing demand for district heating power. Furthermore, the Rauhalahti power plant in Jyväskylä was starting to age, so that acquiring a plant utilising more modern technology made sense. Utilisation of oil fuel had also gone up alarmingly in the ten small district-heating power stations in the Jyväskylä region. Several power plants in Finland utilise CHP technology. In fact, as much as 80 percent of all district heating power comes from the thermal energy generated along with the production of electricity. Construction of Keljonlahti CHP plant started in January 2008. The first test runs of the plant began in autumn 2009. The tests included district heating process tests with the utilisation of peat fuel. The first electricity generation tests started in February 2010. “The Keljonlahti power plant has been in commercial use since 1st July, 2010,” notes Mr. Tero Saarno from Jyväskylä Energy. He is the Chief Engineer in charge of the plant’s operation. The official inauguration of the plant took place on 8th August, 2010. GOOD PERFORMANCE IN FREEZING WEATHER At Keljonlahti plant, the main fuels are wood – in various forms – and peat. Fuel oil is utilised as start-up and reserve fuel. The boiler allows co-firing of different fuels. Output power of the Keljonlahti plant is approximately 480 MW (megawatts). This includes 200 MW of district heating power and 210 MW of electricity. The new plant produces more power than Jyväskylä’s older plant in Rauhalahti that yields a total output of some 370 MW of heat, steam and electrical power. enertec 2011 7
Page 8
Another point in Keljonlahti plant’s favour is that almost 90 percent of the wood and peat fuels used for combustion at the new plant can be utilised for energy. Therefore, process efficiency at Keljonlahti is on a very good level. During the winter of 2010–2011, the district-heating power production of Jyväskylä Energy reached a new record figure. On 18th February, 2011, the power plants in Jyväskylä region together provided district heating power in excess of 400 megawatts. In the morning, the production figure was at its highest: 418 MW. At the time, outside temperature in Jyväskylä was below –30 °C. Keljonlahti power plant in particular was essential in producing district heating for the inhabitants of Jyväskylä. It yielded as much as 225 megawatts of district heating power. MAINTENANCE AND NEW EQUIPMENT Overall, thanks to Keljonlahti plant’s excellent performance, the major part of Jyväskylä’s district heating could be produced by utilising domestic biofuels. At present, the Keljonlahti plant is one of the largest consumers of domestic woodbased fuels in Finland. “Keljonlahti CHP plant has functioned even remarkably well during its first year of operation,” Chief Engineer Saarno gives his opinion. “Ever since the plant was inaugurated, it has been operated at full power. Although the operation has been heavy, the plant has been running in a very reliable manner. No operational problems have appeared, apart from normal wear and tear.” Mr. Saarno mentions that the next annual maintenance for the Keljonlahti plant is scheduled for August 2011. “Every year, the plant is kept in operation for 11 months. After this, a one8 enertec 2011 month annual repair & maintenance period will follow.” The plant is soon to be equipped with some new devices to further enhance its operational performance. “In the near future, an unloading station for incoming biofuels will be built for the Keljonlahti plant,” Mr. Saarno recounts. When the plant is being run at full power, it requires 120 to 150 truckloads of bioenergy fuel every day. Later on, part of the fuel supplies are to be delivered to the plant by rail transport. “A new crushing mill for logs and brushwood will also be added. This mill will not be used to crush stumps, however, since the plant is not currently utilising stumps as biofuel. FUEL PRICES GOING UP Even though CHP production in Jyväskylä region appears to run very smoothly, the continuous flow of domestic woodbased biofuels may eventually become a problematic issue for the plant’s operators. Jyväskylä Energy’s Chief of Procurement, Mr. Ahti Weijo has declared the energy producers’ current worries related to the availability and increasingly high prices of wood fuels. He has noted that due to the limited supplies of timber on the market, the share of transport and other logistics costs in the prices of wood-based biofuels is 30 percent at the very least. For stumps, the percentage is even higher than for other types of wood fuels. The recent closures of paper & pulp and saw mill facilities have affected the prices that the Finnish energy industry is paying for its biofuels. ? MERJA KIHL ARI MONONEN

New crushing mill for Keljonlahti power plant Founded in 1984, Raumaster Oy is one of the leading suppliers of advanced material-handling systems and equipment for the energy and wood industries. Raumaster has delivered various kinds of equipment to Keljonlahti bioenergy plant in Jyväskylä. Next, a large-scale crushing mill for wood fuel will be delivered. K eljonlahti power plant has been in operation for one year already. To ensure the plant’s smooth operation at full power, fuel deliveries need to be flexible and efficient. For this purpose, a new crushing mill was ordered for Keljonlahti plant from Raumaster Oy in March 2011. “The new device to be delivered is a very large-scale crushing mill for wood fuel, having two rotors of a length of six metres,” explains Mr. Pasi Grönroos, Product Line Manager for Raumaster Oy. MORE CAPACITY Mr. Grönroos notes that the crushing mill – to be accompanied by a new receiving 10 enertec 2011 station for bioenergy fuel – will considerably add to the fuel capacity of the power plant. “With a capacity of approximately 250 cubic metres of wood fuel, the crushing mill will be equipped with feeding trays on both sides,” he explains. The mill is to be mostly used for crushing logs and brushwood. It is also suitable for other types of wood materials, such as tree stumps. The main parts for the crushing mill will be manufactured at Raumaster’s machinery works in Finland and Estonia. Some experienced subcontractors will also be used. The mill will be delivered to the power plant by Raumaster’s own assembly team. The delivery will include electrical installations. “Assembly work for the crushing mill will start in autumn 2011. The mill will be ready for operation by January 2012,” Mr. Grönroos states. Raumaster Oy has previously delivered several similar but smaller-sized crushing mills, including one for Jyväskylä Energy’s older power station in Rauhalahti. In addition, Raumaster will supply a similar six-metre crusher to Sweden during 2012. ? MERJA KIHL ARI MONONEN

New waste incinerator plants to produce electricity and heat Ekokem’s first residential-waste incinerator provides district heating power for the towns of Riihimäki and Hyvinkää. All over Finland, waste-to-energy plants are in the construction or planning stages. At Westenergy Oy’s plant near Vaasa, some of the equipment has already been installed. New incinerators in Riihimäki and Vantaa may be next in line. O n the west coast of Finland, Westenergy Oy is in the process of constructing a new residential-waste incinerator plant in Mustasaari near Vaasa. It is designed to produce both electricity and district heating power for Vaasa Electrical Company. “A new waste incinerator is definitely needed. In the next few years, legislation and European Union’s directives will limit the amount of residential waste at refuse dumps,” says Mr. Jan Teir, Managing Director for Westenergy Oy. 12 enertec 2011 DISTRICT HEATING FOR CITY OF VAASA The energy-producing incinerator plant is expected to be in operation by early 2013. The plant will be capable of producing one third of the total district heating power consumed in the Vaasa district. In addition, it will yield electricity for approximately 7,000 residences in Vaasa. This will significantly reduce the need to utilise such fossil fuels as coal and industrial fuel oil in the energy production in the region. The incinerator will dispose of selected residential waste. Such waste materials as metals, glass and paper are to be removed from the waste mass and directed to recycling. Hazardous waste will also be collected separately. However, some non-hazardous industrial waste materials that were previously regarded as useless residues – from paper & pulp and food industries, for instance – can be utilised at the new plant for energy production. The plant is capable of incinerating 150,000 tons of waste per year. EstimatPhotos: Ekokem

ed construction costs will be 135 million euros. EQUIPMENT INSTALLATIONS ARE ALREADY ONGOING The boiler of the Mustasaari incinerator will be a water-cooled fire grate boiler, producing 61 MW (megawatts) of power. Of this, 40 MW will be district heating power. Annually, the plant will produce 80 GWh of electricity and 280 GWh district heating power. Moreover, steam will be provided at 40 bar pressure and +400 °C temperature. The construction of the plant was started in 2009. Equipment installations for the boiler commenced in February 2011. Apart from the boiler itself, related equipment will include cranes, an ashhandling system, and the plant automation system. The boiler was provided by the Swiss company AEE Inova. The plant’s turbine and generator have been ordered from MAN Diesel and Turbo SE in Hamburg, Germany. Installation of the turbine and the generator will take place in the late autumn of 2011, probably in November. The plant building is 160 metres in length and has a height of 42 metres. A bunker for the storage of waste fuel is also under construction. For the entire plant, a total of some 19,000 cubic metres of concrete was needed. The plant’s chimney rises to the height of 75 metres. Chimney gases will be cleansed with lime and active coal. ParEkokem Oy’s existing incinerator facility in Riihimäki. The first residential-waste incinerator is seen on the left. ticles will be removed from smoke gases by hose filters. The cleansing system, provided by LAB S.A., will be installed in the summer of 2011. SERIOUS TESTING Once the equipment installations have been completed, the plant will be subjected to a thorough technical testing process. Overall, close to 10,000 different tests or check-ups will be carried out in the course of spring 2012. Operational tests for the plant are expected to commence in July 2012. Commercial operation will start in January 2013. The Mustasaari plant and Westenergy Oy are joint ventures, co-owned by five waste-management companies in the enertec 2011 13

EKOKEM OY HAS EXPANSION PLANS In southern Finland, Ekokem Oy’s hazardous-waste incinerator plant in Riihimäki has been in operation since the 1980’s. Ekokem Oy expanded its operations to the domain of burning non-hazardous waste to energy when the company’s first residential-waste incinerator was completed in 2007. The plant provides district 14 enertec 2011 heating power for the neighbouring towns of Riihimäki and Hyvinkää. The newer plant has an output power of 55 MW. It has the annual incineration capacity of 150,000 tons of waste. Utilising fire grate boiler technology, the plant was designed and constructed by Fisia-Babcock GmbH. Smoke gases of the plant are cleansed by the same filters that are used by the adjoining hazardous-waste incinerator. Control room for Ekokem’s existing incinerators in Riihimäki. Now, Ekokem Oy is planning to construct a second energy-producing residential-waste incinerator plant in Riihimäki. The plant is to produce additional district heating power for Riihimäki and Hyvinkää. Furthermore, it will produce quite a lot of electrical power. Because of this, new 110 kV electrical power transmission lines are to be constructed between Ekokem’s plant in Riihimäki and the Hikiä switching station in the neighbouring municipality of Hausjärvi. With the inauguration of the new plant, Ekokem is hoping to significantly improve its electrical power production capacity. The project will also include the construction of a pre-processing plant for waste. In addition to regular residential waste, the plant is to incinerate a certain amount of industrial and retail-trade waste materials, construction-site residues, and
Page 15
various kinds of wooden and plastic materials. A new cleansing system for chimney gases is to be built for the new wasteto-energy plant. INCREASING OPPOSITION IN RIIHIMÄKI AND VANTAA In the environmental-impact report compiled with the aid of Ramboll Finland Oy’s consultants, the plant project was considered feasible. An environmental permit for the plant project was granted in November 2010, allowing the construction to start. Estimated construction costs are approximately 60 million euros. The plant is expected to be completed in late 2012. At the end of 2010, a local environmentalist agency submitted a complaint against the Riihimäki plant’s construction plans to Vaasa Administrative Court. The agency was particularly concerned about Ekokem’s plans related to emission regulation and also argued that the incineration of some hazardous materials along with regular waste may constitute a high risk of detrimental environmental impact. In addition to Westenergy’s and Ekokem’s plants, new energy-producing waste incinerators are being planned in the cities of Oulu, Vantaa, Rovaniemi, and Kouvola. In Vantaa near Helsinki, a new incinerator plant is in its initial planning stages. The Vantaa plant, to be situated next to highway E18, would yield energy and dispose of residential waste produced in the capital city of Helsinki and the surrounding communities. This project has been facing increasing opposition from its would-be neighbours since it turned out that the plant might be also utilised for the incineration of hazardous weatherproofed pressure-impregnated timber materials. ?

Nirafon acoustic cleaning system keeps Boiler Plants clean Nirafon Oy designs and develops effective customer oriented acoustic cleaning systems. E stablished in 1986 Nirafon Oy has a 25 year experience and the products are spread worldwide. The market area of Nirafon Oy is Energy and Process Industry; mainly Power Industry. Most of Nirafon cleaners are installed in Boiler plants. The Nirafon range of products can keep whole boiler plants clean from the furnace to the fans and filters. Conventional pneumatic acoustic cleaners are used in lower temperature areas such as boiler banks, economisers, air preheaters, ducts, channels cyclones and filters, bag houses and ESPs. In higher temperatures up to 1 500 ºC, furnaces and superheaters, the NCSD (Nirafon Cleaning Sound Device developed by Nirafon) is used. The NCSD creates a high sound pressure impulse by burning a small amount of gas in its combustion chamber. This sound pressure pulse is a lot stronger than in conventional acoustic cleaners. The Nirafon acoustic cleaning system can be used in many different kinds of boilers such as CFB boilers, BFB boilers, Grate boilers, PC boilers and Recovery boilers. Also we can clean many varieties of fuels in boilers such as coal, peat, wood, biomass, waste, black liqueur etc. The Nirafon equipment has proven its effectiveness also in a challenging task of cleaning superheaters of waste to energy plants. Nirafon equipment is used to replace the pipe wearing shot cleaning or soot blowing with steam completely or minimising the use of the shot and steam cleaning. ?

Bad news for wind power in Europe 2010: onshore wind power installations (8.4 GW) were down 13.9% compared to 2009 (9.7 GW). Good news for wind power in Europe 2010: offshore wind power installations grew 51% from 582 MW in 2009 to 883 MW of last year. With 308 new offshore wind turbines being installed in 2010, offshore wind power made a new record in Europe, making people wonder if the future of wind power lies with the sea breeze. enertec 2011 21 Photos: Vattenfall / Chris Laurens
Page 22
A ccording to the European Wind Energy Association (EWEA), some 883 MW of new offshore capacity was developed in 2010, bringing Europe’s offshore installed capacity to a total of 2,964 MW. Worth some €2.6 billion in 2010, there are more than 1,100 offshore wind turbines currently operational in Europe, which in a normal wind year would produce 11.5 TWh of electricity. The UK is the leader of pack leader with a total of 1,341 MW, followed by Denmark with 854 MW. The Netherlands, Belgium and Sweden have 249 MW, 195 MW and 164 MW, respectively. Germany possesses 92 MW, Ireland 25 MW, Finland 26 MW and Norway manages 2.3 MW. In the technology front, last year 29 new offshore turbine models were announced by 21 manufacturers. The total for the last two years is 44 (from 33 manufacturers) which means that 2010 was no fluke. TAKE NOTHING FOR GRANTED Total investments in new wind power plants remained unchanged at € 13 billion, compared to 2009, due to the larger share of the said offshore wind capacity. Christian Kjaer, Chief Executive Officer of EWEA, was glad to see offshore wind power perform so well, but also worried about the onshore operations. According to Kjaer, this development means that the industry cannot take continued financing of renewable energy for granted. “Better access to financing is urgently needed, and the European Union must act without delay to prevent Europe losing its leadership in wind power and other renewable technologies. “ Newly installed capacity in 2010 (9.3 GW) was 10% down from 2009 (10.3 GW). Kjaer observed that remarkable growth in the onshore wind markets of Romania, Poland and Bulgaria could not make up for the decline in new onshore installations in Spain, Germany and the UK. 22 enertec 2011 2010 Offshore Wind Power Market ?? ???????????????????????????????????????????????????????????????????? grid-connected in 2010, totalling 883 MW – a 51% increase on the previous year ?? ???????????????????????????????????????????????????????????????????????? was partially grid-connected, and one wind farm was completed but not grid-connected ?? ??????????????????????????????????????????????????????????????????????? work on four new projects CUMULATIVE OFFSHORE WIND POWER MARKET ?? ??????????????????????????????????????????????????????????????????????????? farms in nine European countries.

2010 than any other year in history – an increase of 31% compared to 2009. Nevertheless, the figures also reveal that for the first time since 2007 wind power did not install more than any other generating technology. NORTH WIND RISING As offshore wind power keeps heading north, the Nordic countries are fully investigating the options for additional capacity. Leading the way is the proposed 1.5 GW Finngrunden project. Wind development company wpd wants to build Scandinavia’s largest offshore wind park about 40 kilometres from the mainland, east of Gävle. The project’s scope will include 300 wind turbines of 5 MW capacity, a combined power of 1,500 MW. Annual production is expected to be around 5.5 TWh. 24 enertec 2011 The construction phase of the wind park isn’t expected to start until 2014, however. According to estimates, the offshore wind park could provide up to two million people with electricity. This demonstrates that there are solid geographical positions to carry out large-scale development of offshore wind energy on the Baltic Sea. The driver for such ventures is obvious: as Sweden wants to make half of its energy via renewable means within the decade, offshore wind power – lots of it, in fact – is crucial in the mix. OFFSHORE NEEDS STATE SUPPORT Wpd is also active in Finland, where Suurhiekka offshore wind power park project received a water permit in February – making it the first open sea project to obtain the permit. The company could start construction in 2014, if the state provides a handsome enough subsidies package. The situation in Finland is very similar to that of Sweden – the Government is committed to renewable energy and offshore capacity plays a key role in meeting the set targets. For these two countries, EWEA predicts a big increase in installed offshore wind power capacity by the decade’s end. While in 2008 Finland had a total of only 24 MW in offshore, the figure could be between 400 MW and 1,000 MW in 2020. For Sweden, the estimate by 2020 is as high as 3,000 MW. The starting level for Swedes is also considerably better at (133 MW in 2008). ? SAMI J. ANTEROINEN

Foster Wheeler delivers new generation CFB boiler to Norrköping Foster Wheeler Energia sold an 84 MW circulating fluidised bed (CFB) boiler to E.ON Värme Sverige AB in the summer 2008. The CFB boiler was supplied to E.ON Värme’s new plant in Norrköping, Sweden, and it represents the latest generation of Foster Wheeler’s circulating fluidised bed technology for waste-to-energy applications. 26 enertec 2011 F oster Wheeler Project Manager Titta Joukanen says that production test runs – i.e. producing the first steam for the network – were performed already in September 2010. The plant turnover over to the customer on 22 December 2010 – almost two months ahead of schedule. “The plant is working as planned, and, according to preliminary guarantee test results, both emission and performance targets are well met,” Joukanen says. Designed to be fired on recycled fuel, the boiler delivers high steam parameters, high efficiency, and low emissions. Over 90 % of the fuel used is renewable and comprises demolition wood, wood chips, and refuse-derived fuel. The sand in the furnace bed minimises the effect of fluctuations in fuel quality. The plant contributes to a reduction in local carbon dioxide emissions of 120,000 tCO 2 /a. RECYCLING IS KEY The refused-derived fuel (RDF) used is produced from sorted municipal and industrial waste. Efficient sorting is of key importance to ensure a steady stream of fuel that can be fired effectively. The Norrköping plant generates electricity for the grid, district heat, and process steam for local industrial needs. The first CFB boiler of this specific type has been in commercial use in Lomellina, Italy, for a couple of years now. The experts at Foster Wheeler are of the
Page 27
opinion that these two projects are just the beginning: “As sorted waste is used effectively as a fuel more and more, we feel that the market potential for similar boilers is very good both in Europe and Asia,” Jouka nen comments. Unlike conventional steam generators that burn the fuel in a large high-temperature flame, CFB technology does not have burners within its furnace. Fluidisation of bed material, fuel ash and sand, is achieved by blowing air through the bed material. The CFB combustion takes place in the low temperature and heat transfer is obtained through the circulating material. Due to the large heat capacity of the circulating bed, combustion is stable and no supporting fuels are required. The intense turbulence ensures good mixing and combustion of the fuel thus resulting high combustion efficiency and low level of emissions. GLOBAL LEADER Presently, Foster Wheeler is the world’s leading supplier of CFB boilers, with an approximately 58 % market share of the installed base of biomass CFB boilers for global market in the 2001 to 2010 time period. The FWEOY Group and other Foster Wheeler companies have delivered close to 500 fluidised bed boilers, of which over 300 have been CFB units. The FWEOY Group operates at two locations in Finland, Espoo and Varkaus, and has subsidiaries in Sweden and Germany. ? SAMI J. ANTEROINEN enertec 2011 27

Dalkia turns to a greener page The start-up of the Metso HYBEX power boiler delivered to the energy service providing company Dalkia in Facture in southwest France, was an important landmark. The boiler is the largest biomass boiler used for energy production in France. Complete automation of the power plant enables Dalkia to benefit from efficient process control, compatible reporting and communication. With power production of 50 MW, the biomass plant counts among the largest in Central Europe. 28 enertec 2011

30 enertec 2011 T he Dalkia power plant with an extensive solution for biomass processing was commissioned in fall 2010 and is running successfully. The combined heat and power plant mainly uses bark and forest residues as fuel to produce 50 megawatts of electricity for the national grid and 74 megawatts of process steam for Smurfit Kappa’s paper mill. Dalkia is the energy division of Veolia Environnement, a globally operating specialist in environmental services. Bio-energy is playing a growing role in the creation of sustainable energy systems worldwide. According to Jouni Kinni, Sales Manager, Power business line, Metso: “The French delivery included the boiler, flue-gas cleaning and fuel handling systems as well as complete automation of the power plant, which ensures among other things, that the customer benefits from compatible reporting and communication. For the customer, centralising the process equipment required for biomass handling with the same supplier reduces the likelihood of delays during construction and ensures that all equipment is seamlessly compatible.” The good performance of the Dalkia biomass plant demonstrates Metso’s know-how and experience in action. A full-scope delivery with a wide range of automation solutions to a large greenfield plant that fulfills EU directives and local regulations adds convincing credit to Metso’s track record. FULL-SCOPE SOLUTION FOR MANAGING EMISSIONS Dalkia’s full-scope biomass processing solution from Metso provides both immediate and long-term advantages for the environment, the power generation process, productivity and resource management. Proven solutions in BFB (Bub???????????????????????????????????????tion and fuel handling enable Dalkia to operate the plant in the framework set by tight emission guarantees. Plus, Dalkia will be able to meet future regulations as well, if changes are made in the fuel base. Due to higher process steam values, the ratio between electricity and heat is considerably higher than before. The entire power plant operation is concentrated within one plant that has one control system and reporting system for utilising steam produced in the new power boiler and the old recovery boiler. All this creates a base for cost-efficient maintenance and plant operation. The boiler and flue gas cleaning system are designed so that if the plastic rejects from the mill’s recycled paper would be added to the fuel mixture in the future, the equipment is ready for it with minimum modifications.

ENVIRONMENTAL APPLICATIONS WORK ON TOP OF METSO DNA INFORMATION SYSTEM The environmental applications delivered to Dalkia marked the first Metso emission monitoring and reporting system delivery to a greenfield plant in France. All emission monitoring and reporting comply with EU directives. The customised automation solution produces all necessary information for self-monitoring and authority/compliance reporting in required units, taking into account Dalkia’s environmental permit and special needs of self-monitoring. The environmental applications are designed to give a full view about emission levels to a wide range of users and authorities. The plant is able to monitor emission levels on-line. Diverse reports facilitate maintenance planning, emissions analyses as well as updating and managing of initial data, and provide authorities with information according to EU directives. ?

New-Generation Arc Protection System to Improve Safety and Reduce Damages U TU Elec Oy specialises in electrical distribution and networking. The company designs, manufactures and imports various types of products for power transmission and industrial applications. “In early 1990s, UTU Elec launched the first-generation arc protection systems,” says Mr. Kari Tuominen, Business Unit Manager for UTU Elec Oy’s electrical distribution division. Arc short-circuit is a failure event that causes explosive heat and pressure effect. It may result in extensive material damage and disruptions in electricity distribution. In worst-case scenarios, electric arcs 32 enertec 2011 can even be lethally dangerous for operating personnel. Therefore, a high-speed response to an electric arc is called for. “The new fifth-generation Falcon and Falcon Lite arc protection systems – typically installed in an electrical distribution centre – contain light sensors, connected to optical fibre cables.” ”In addition, a current relay in the system keeps track of excessive electrical charges,” Mr. Tuominen explains. “If light and a power surge are detected simultaneously, the system will interpret this as an electric arc and consequently trigger a feeder switch in less than one millisecond.” According to Mr. Tuominen, UTU Elec’s arc protection systems are largely being exported to Asian countries – notably China – as well as Europe, Canada and United States. “UTU Elec is also the market leader in recloser sales in Finland. Reclosers are used for reducing power failures in electric overhead distribution networks,” Tuomi nen mentions. ? MERJA KIHL ARI MONONEN

Handling ash and screening water at power plants Keljonlahti CHP plant in Jyväskylä. K opar is a leading manufacturer of ash handling systems for the power industry and utility plants. Kopar ash handling systems are based on the years of knowledge and experience of Elmomet. The company is specialised in conveying of ash, both mechanically and pneumatically, and is able to offer flexible solutions in assessing the need of the individual customer. Recently ash handling, lime injection and sand recycling systems along with storage silos and dry and wet discharging equipment were supplied to Keljonlahti power plant in Jyväskylä, Finland. A further particular Kopar expertise is the raw-water intake systems. The need for effective water cleansing solutions is growing. Industrial plants take surface water or stored water from lagoons and rivers as process or cooling water. The quality of raw water is highly variable in many places thus requiring more filtration before usage within sensitive production processes. Kopar bar screens, travelling basket filters and drum basket filters are being used within many different types of power generating plants extending from nuclear power plants to bio energy plants.

Nuclear Power after Fukushima T he Fukushima accident reminds us all about the unique risks associated with nuclear power. Radioactive releases spread with wind and contaminate regions. While rational from public safety perspective, the evacuation confirmed the impression of the size of the risk. The fact, however, remains that no lives were lost as a result of radiation caused by the accident. The direct loss to the plant owner and its shareholders is substantial. Radioactive contamination causes losses to farming and fisheries, and evacuation will take its time and become costly. Third-party costs are to be paid by the company, and possibly by the state of Japan. As reactor core damage seems to occur relatively frequently, once every 25 years, proper planning of decontamination is needed. It is not acceptable to contaminate the land around a plant for decades. In addition to the costs of updating the safety systems, the indirect costs to societies are even higher. The envisaged nuclear renaissance will be delayed. This will increase the demand for other energy sources, in practice fossil fuels, meaning higher energy prices, and consequently economic growth will slow down. Ironically enough, this will make nuclear projects increasingly profitable. Combating global warming is becoming more difficult, and the race for energy resources increases geopolitical tension: energy politics have always been subordinated to foreign politics, which in turn, where necessary, use military force, as we have frequently witnessed in the history of the oil business. Despite the Fukushima accident, energy remains indispensable in any nation’s infrastructure. National economies benefit from cost-effective power generation. Its capacity to generate local well-being is far beyond that of e.g. oil business where the product is exported and used abroad, The author has a Tech. Lic. Degree in Physics. During his early career he worked for STUK, the Finnish Radiation and Nuclear Safety Authority, as a Radiation Safety Inspector of nuclear power plants, and later as a Safety and Environment Engineer in the two nuclear power companies in Finland. From 1985 he has worked in Corporate Communications, partly to promote the general understanding of nuclear power, and after a position as Executive Vice-President, Communications in Fortum, he in 2001 joined JKL Group Oy, a communications consultancy firm, owned by Publicis Groupe where his tasks have varied from Senior Advisor to Managing Director. Before joining the JKL Group Antti Ruuskanen was President of European Nuclear Society’s Communications Committee. and profits are enjoyed by a foreign oil giant. Nuclear facilities have three lifetimes: technical, economic and political. The last mentioned has become increasingly relevant and consequently investment risks have increased. The public tolerance of nuclear power, a major factor of energy politics, rests heavily on national safety regulators. Their credibility cannot be underestimated. This underlines the fundamental duty of all actors to openly communicate on all levels of a society. Owing to all this, and in spite of the Fukushima accident, nuclear power with elevated safety standards is severely needed, together with renewables, as a source of non-fossil energy. ?

Nuclear power still needed VTT’S RAUNO RINTAMAA ARGUES THAT ALL FORCES MUST BE BROUGHT TO BEAR AGAINST CLIMATE CHANGE In the wake of the Fukushima disaster, anti-nuclear sentiment has been on the rise across the world. A similar backlash occurs every time when there is a serious catastrophe – the same development was seen with Harrisburg and Chernobyl. Due to Harrisburg accident, the US administration pulled the plug on all nuclear power projects that were in the pipeline at the time. The flipside of things is that had the American nuclear power sector kept on its development path at the time, today the country would be a nuclear power giant – and its CO 2 emissions would be only half of what they are today. R auno Rintamaa, Vice President of Business Solutions, Energy, at VTT, says that the Climate Change has not gone anywhere because of Fukushima. Solutions are still desperately needed to combat Climate Change and nuclear power is a significant instrument in the green toolbox. In fact, the challenge ahead is so huge that all methods are needed: “Nuclear power and renewables should go hand in hand. Nuclear power is a solid anchor which brings predictability to the energy price level. This, in turn, will buy time for renewable forms of energy such as wind power and solar power to ripen.” PALER SHADE OF GREEN? It’s not only the customers who need to know the amount of zeros on their energy bill: also the Finnish energy-intensive industries depend on this type of transparency. Rintamaa is aware that in some parts of the world renewables initiatives are used as a form “greenwashing” but the renewables package approved by the State is the real deal in his mind: “The renewables package is unique in the entire European Union. It has the ability to generate a lot of green collar jobs and open brand new development and export prospects for technology industry.” enertec 2011 37 Photos: VTT

VTT is a forerunner in the development of nuclear safety expertise and advanced nuclear technologies and has about 200 nuclear experts and modern experimental facilities and modelling tools. VTT also coordinates the national R&D programme (SAFIR2010) on Nuclear Power Plant Safety (2007–2010) and the EURATOM–Tekes fusion technology co-operation in Finland. UNIQUE INSIGHTS Furthermore, VTT is also an active partner in research regarding advanced future nuclear fission technologies among international fora, such as the Sustainable Nuclear Energy Technology Program (SNETP). Rauno Rintamaa is just finishing his stint as the Chairman of the SNEPT Executive Team. His term lasted for three years and provided unique insights into issues involving nuclear technology today and tomorrow. Rintamaa was the first ever Chairman of the Executive Committee. According to Rintamaa, Finland has benefitted from the “national custom” that authorities, researchers and corporations engage in dialogue and work together to take the cause of nuclear power onwards. VTT has had a large role to play in the development, since the organisation’s expertise is recognised everywhere in the world. “Over the years, more and more requests for our services have come from abroad,” Rintamaa says, noting that in addition to nuclear power, also bio and wind energy expertise are key areas for VTT’s 38 enertec 2011 “brain exports”. A newer area is Smart Grids as VTT in studying the best ways for the citizens to take advantage of the new intelligent systems – the so-called “Internet of Energy”. STAY THE COURSE With regards to nuclear power, Rintamaa says that the formula for steady development over the years involves good planning and wise allocation of (often sparse) resources. “The strategic vision on the development of nuclear research has been a good one.” Domestically, VTT is the major technical support organisation for the authorities and the Finnish nuclear industry, and performs contracted research on topics related to nuclear safety, plant life management and nuclear waste management. VTT is also the coordinator of the Network of Excellence (Nulife) Nuclear plant life prediction. ? SAMI J. ANTEROINEN

As a massive tragedy befell Japan, the EU wasted no time to reevaluate the safety standards and resilience of European nuclear power plants. Energy Commissioner Günther Oettinger called together an emergency meeting of ministers, diplomats, regulators and representatives of energy companies who operate nuclear reactors. The discussion in Brussels on 15 March focused on “stress tests” for nuclear power plants in Europe. Photos: TVO / Hannu Huovila S oon it was agreed that the safety assessments will be defined and adopted by June and should be carried out during the second half of the year. However, since nuclear safety is an area of shared competence between the EU and its Member States, the tests would be performed on a voluntary basis. Nuclear industry representatives have been sympathetic to EU’s wishes, stating they can contribute to the initiative by defining safety criteria and by assisting in the implementation of those tests in cooperation with national safety authorities. The European Commission would also very much like to see neighbouring countries, such as Russia and Turkey, take part in the stress tests. Furthermore, the Commission is eager to enhance the role of ENSREG (the European Nuclear Safety Regulators Group) in all this. DIRECTIVE REBORN The EU Nuclear Safety Directive, adopted in 2009, is about to assume an added air of importance in the light of recent events. The Directive was due for mid-term review in 2014, but may well be put on the fast track now – and more legislation could easily follow. In Finland, the Fukushima disaster is placed against an interesting backdrop: there is one nuclear reactor presently under construction, and permits have been issued by the State for two extra ones. After Fukushima, some members of the Finnish parliament have been arguing that the state should pull the plug on the new projects altogether. Due to the Parliamentary elections, the whole topic has politicised perhaps even more quickly than normally would have been the case. In addition to the politicians, also the officials are on the move. Finnish Radiation and Nuclear Safety Authority STUK announced that it will start to assess the safety systems of Finnish nuclear power enertec 2011 41
Page 42
plants, in line with the EU’s wishes. For example, electricity feed and flood protection in risk situations will be assessed by the authorities. A similar check was performed a couple of years ago as the water level rising in the Gulf of Finland generated concerns. TROUBLE WITH THE TYPE? The nuclear safety authorities in France have assessed that Fukushima may bring about additional costs and delays for EPR type reactors – like the ones presently being built in Olkiluoto, Finland, and also France. Still, Olkiluoto 3 reactor – with TVO as the customer – has already gone through a series of tests recently and TVO claims that no need for modification of the plans surfaced during that process. Neither does TVO expect further delays for the construction of OL 3 – which is good news considering that the reactor is already several years behind schedule. TVO has also tried to communicate to the public that the nuclear scene in Finland is very different from that of Japan – for example, Finland is at very low risk from both large earthquakes and tsunamis. Nevertheless, earthquake resistance – among other safety measures – at Olkiluoto has been improved in many ways over the years and is being continuously maintained. CONTROL AT ALL TIMES All three Olkiluoto units have severe accident management systems ensuring environmental safety. The OL3 safety systems will fulfil all the present regulatory requirements and have, from the beginning, been built as such that no radioactive substances will be released into the environment even in case of a severe accident. In addition, OL3 will have a core melt cooling device. The containment has a severe accident cooling system limiting the 42 enertec 2011 Olkiluoto 4 modelling photo. containment pressure and temperature preventing need of release. The severe accident management strategy for the existing OL1 and OL2 is based on the principle that there will be no uncontrolled release even if severe accident occurs. The containments are equipped with a filtered venting system designed for severe accident conditions. And while securing electricity became an Achilles’ heel at Fukushima, the electric supply of the emergency cooling systems of Olkiluoto plant units has been ensured in multiple ways. Safety-critical

systems are equipped with several backup power supply sources guaranteeing the power supply for these systems even if something exceptional occurs. LONG AND WINDING ROAD The Finnish Parliament gave a green light to TVO’s and Fennovoima’s new nuclear plant projects in July 2010. Since then both companies have been hatching their plans for the implementation in relative peace and quiet – but Fukushima has changed all that. Especially the situation of the newcomer Fennovoima is ripe with challenge. Fennovoima was founded only in 2007 and the company has 70 owners, with German energy company E.ON among them. Fennovoima is supposed to choose the location of the plant this year, with the enertec 2011 43
Page 44
northern municipalities of Pyhäjoki and Simo as the alternatives. In a perfect world, construction phase could begin in 2012 and the nuclear power plant could start producing electricity in 2020. So far, it appears that Pyhäjoki and Simo (as well as the municipalities around them) continue to support Fennovoima’s project and want the nuclear power plant to be located in their area. A more pressing question has been, will E.ON stay committed to the project, especially as Germany has assumed a very anti-nuclear stance of late. Without E.ON, the Finnish partners lack the muscle to see the massive undertaking through. Anders Olsson, Senior Vice President of E.ON Nordic has stated that the events Olkiluoto 1 and 2. 44 enertec 2011 in Japan are, indeed, something that will be discussed with the partner network but the company remains committed to the Fennovoima’s project. FOURTH TIME’S THE CHARMER TVO is in a better position in the sense that Olkiluoto is a tried-and-true site – a good fit from the perspective of construction, production, maintenance, and waste management of nuclear power. The municipality of Eurajoki has expressed its support for the OL4 project and the associated spent nuclear fuel disposal solution. In addition, the majority of Eurajoki citizens endorses the project. The necessary infrastructure for the new unit largely already exists in Olkiluoto. The land area has been zoned and there are good water conditions for cooling the new plant unit. The connection of the new plant unit to the national high-voltage grid will be straightforward enough and the location of a new power transmission line has been taken into account in regional as well as Olkiluoto area land use plans. Still, the question that TVO may have a hard time answering is: “Why should OL4 be a winner, while OL3 is a big disappointment so far?” In TVO’s mind, of course, the experiences – as ‘trial and error’ as they might have been – from OL3 will help out with OL4. ?

Final touches for Olkiluoto 3 design T he Finnish engineering company Finnmap Consulting Oy has carried out a major part of the structural design for Olkiluoto 3 nuclear plant reactor building. Currently, the shielding structures for the reactor are under construction in Eurajoki on the west coast of Finland. The building work will be completed by the summer of 2011. For the Olkiluoto 3 project, Finnmap Consulting has worked in close cooperation with ÅF Enprima Ltd. For the structural design work, the companies formed a joint-venture consortium FINNprima. “Our first design task in Olkiluoto was the detail design of the reinforced concrete common base slab structure for the NI Buildings, in 2004,” says Mr. Jarno Berghäll, Business Unit Manager for Finnmap Consulting. Design work for the Reactor Building was started in 2005. Finnmap prepared the Detail Design for the Reactor Building structures. “In addition, we made the Design for the external Stair Cases and for the whole Airplane Crash (APC) shell structure. Supplementary design work will continue throughout the year 2011.” Mr. Berghäll expects that some of the final structural detail design may even take place in 2012. “Of Finnmap Consulting’s personnel, approximately 30 to 60 professionals have constantly been engaged in Olkiluoto 3 design work in the course of the last few years,” he mentions. Furthermore, Finnmap’s subsidiary company AIRIX has taken part in overseeing the assembly work and quality control of various kinds of technical equipment at Olkiluoto 3 building site. ? enertec 2011 45 Photo: TVO / Hannu Huovila

Stand-by emergency diesel engines require scheduled maintenance PATRIA Aviation Oy is a specialist company in the field of servicing emergency diesel engines utilised by nuclear power plants. Such stand-by generator engines are needed to ensure that the cooling systems of the reactor will remain operational in the event of malfunction in the normal electric supply system. S enior Manager of Diesel Engine Business at PATRIA, Mr Seppo Tamminen, says that PATRIA Aviation Oy has been in the business of servicing emergency diesel engines for nuclear power plants since the early 1990’s. “Maintenance intervals of the standby diesel engines vary slightly from plant to plant,” he explains. “In general, the time between overhaul (TBO) of the NPP emergency diesels is 16 years, due to the ageing of rubber parts if nothing else. This is when a diesel engine needs to be overhauled even if it has been used only during the monthly test runs.” According to Mr. Tamminen, standby emergency diesel engines are utilised in all nuclear power plants around the world. “For emergency situations, the stand-by power requirement is from 1 to 2 percent of the power plant’s nominal output. For example at NPP Olkiluoto I the power output is currently 880 MW (meg46 enertec 2011 Photos: PATRIA Aviation Oy awatts) and there is approximately 8 MW stand-by emergency power reserve. This has been arranged by four diesel generators. NPP Olkiluoto II plant utilises a similar arrangement.” PATRIA TO EXPAND ITS MAINTENANCE OPERATIONS In addition to its domestic operations, PATRIA Aviation Oy frequently takes care of the maintenance of emergency diesel engines of nuclear plants abroad. Such customers are for example Vattenfall Ringhals in Sweden, as well as the giant French energy company EdF (Électricité de France). EdF has nearly 60 nuclear power plants in France. In more than 30 plants emergency power has been utilised by 4.8 megawatt Wärtsilä-SACM UD45 diesel engines. “We have maintained EdF’s diesel engines for some time. At present, we are preparing a service contract extension with EdF. Overall, EdF has almost 70 WärtsiläSACM diesel engines.” “PATRIA Aviation aims to expand its diesel engine maintenance business in other European countries as well,” Mr. Tamminen states. A French-made 20-cylinder Wärtsilä-SACM diesel engine is assembled at PATRIA’s diesel engine repair workshop. One of the most critical phases of engine maintenance is installing of the inspected and approved piston/ connecting rod assemblies into the cylinders.

Apart from stand-by emergency engines, PATRIA Aviation takes care of the maintenance of also other types of diesel engines, including marine diesel engines, power packs for main battle tanks and armoured vehicles, and heavy earth moving equipment engines. PATRIA is an Authorized Service Dealer for MTU engines and overhauls also Caterpillar and other diesel engines. More than 30 professionals are employed by PATRIA as diesel engine maintenance specialists. ? An overhauled Wärtsilä-SACM UD45 V20 engine is connected to PATRIA’s diesel engine test facilities.
