Nuclear Power in Finland
(Updated April 2013)
- Finland has four nuclear reactors providing nearly 30% of its electricity.
- A fifth reactor is now under construction and two more are planned.
- Provisions for radioactive waste disposal are well advanced.
Finland typically generates about 80 billion kWh per year, the majority from imported fossil fuels (mostly coal and some gas). Coal is imported from Russia and Poland, all of its gas comes from Russia.
In 2011 electricity production was 73.5 TWh, and of this nuclear provided 23 TWh, coal 16 TWh, hydro 12.5 TWh, gas 10 TWh, biofuels 11 TWh, and net imports were 14 TWh, mostly from Russia, some from Estonia. Net export to Sweden was 2.8 TWh. Capacity is about 16.7 GWe. Finland has a very high per capita electricity consumption - some 15,000 kWh per head per year.
The country is part of the deregulated Nordic electricity system which faces shortages, especially in any dry years, when hydroelectric generation is curtailed.
Since the 1930s energy-intensive industry has invested in large-scale energy production in Finland, rather than leaving it entirely to specialized utilities. More recently energy-intensive companies have seen joint ownership of electricity production with power sold at cost price to shareholders as an important means of protection against the increasing prices and volatility of liberalised electricity markets. This so-called Mankala model is also effective in risk-sharing. It is a distinctive of Finland in relation to capital-intensive nuclear capacity.
Operating nuclear reactors
Finland's four existing reactors (about 2700 MWe net total) are among the world's most efficient, with an average lifetime average capacity factor of over 85%aand average capacity factor over the last ten years of 95%. Two boiling water reactors supplied by the Swedish company Asea Atomb are operated by Teollisuuden Voima Oy (TVO)c; and two modified Russian pressurized water reactors (VVER) with Western containment and control systems are operated by Fortum Corporationd.
Finnish reactors are remarkable in the extent to which they have been uprated since they were built. TVO's Olkiluoto 1 & 2 started up in 1978-80 at 658 MWe net (690 MWe gross); 30 years later, they were rated at 860 MWe net each (30% more) and their lifetime had been extended to 60 years, subject to safety evaluation every decade. TVO now proposes progressively to uprate them further to 1000 MWe each. A 25 MWe uprate of Olkiluoto 1 over May-June 2010 was part of this, and involved replacement of low-pressure turbines. A similar uprate of unit 2 to almost 910 MWe gross was undertaken over May-June 2011. With uprates, TVO aims “always to have 40 years of remaining technical lifetime”.
Fortum's two VVER-440 reactors at Loviisa have been uprated from 445 net (465 MWe gross) in 1977-80 to 488 MWe net (510 MWe gross). They have an expected operating lifetime of 50 years, though were originally designed for only 30. A 20-year licence extension was granted by the Radiation and Nuclear Safety Authority (STUK) in mid-2007, taking them to 2027 and 2030, subject to safety evaluation in 2015 and 2023. In 2008, Areva commenced a six-year renewal project to install modern digital instrumentation and controls systems at the plant.
Finland's operating nuclear power reactors
Nuclear expansion: fifth unit
Following an application made in November 2000 by TVO, in May 2002 Finland's parliament voted 107-92 to approve building a fifth nuclear power reactor, to be in operation about 2009. The vote was seen as very significant in that it was the first such decision to build a new nuclear unit in Western Europe for more than a decade. A similar proposal had been rejected in 1993, but the political climate throughout Europe had since become much more favourable to nuclear energy.
TVO's application for a new reactor was based primarily on economic criteria (lowest kWh cost, lowest sensitivity to fuel price increases)f, but it noted the considerable energy security and emissions savings benefits. Government support for the proposal was based mainly on climate policy, while its detractors supported a massive increase in natural gas use (from Russia) for electricity generation.
The site of the new unit was decided in October 2003 to be at TVO's Olkiluoto plant in the southwest, with two nuclear reactors already in operation there.
Following the submission of tenders by three vendorsg, in October 2003, TVO announced that Framatome ANP's 1600 MWe European Pressurized Water Reactor (EPR) was the preferred reactor on the basis of operating cost. Siemens was contracted to provide the turbines and generators. TVO signed a €3.2 billion contract with Areva and Siemens for an EPR unit in December 2003. Meanwhile bids to TVO from its various owners for shares of the 1600 MWe expected net output totalled 2000 MWe.
Construction started May 2005 but delays have been encountered, particularly on the reactor section. Fuel loading was expected at the end of 2012 with commercial operation in 2013, though TVO has since projected August 2014 and then 2016 for commercial operation. The cost overrun is considerable, possibly to €8.5 billion and Areva has already made provision for writedown of €2.7 billion on the €3.3 billion project in its accounts. In December 2011 it was 82% complete, according to Areva. The first EPR unit at Taishan in China is expected to be in service by the end of 2013.

Nuclear expansion: sixth and seventh units
In March 2007, TVO and Fortum commenced environmental impact assessments (EIA) for new nuclear power units at the Olkiluoto and Loviisa sites respectively. This is the first phase of licensing a new nuclear plant. It is followed by a decision in principle (by parliament), construction licence, then operating licence.
TVO's 2008 application for a Decision in Principle to construct a 1000-1800 MWe PWR or BWR unit as Olkiluoto 4 was granted in May 2010. TVO is looking at building another EPR (of about 1650 MWe), but is also considering Toshiba's version of the ABWR (approximately 1650 MWe), GE-Hitachi's ESBWR (approximately 1650 MWe), Mitsubishi's EU-APWR (approximately 1650 MWe) and the slightly smaller Korean APR-1400 (approximately 1450 MWe) – all these net capacity figures, from TVO3. In March 2012 TVO formally requested bids and received five in January 2013, It said it expected to apply for a construction licence by mid 2015 and have the unit on line about 2020.
Fennovoima Hanhikivi 1
In June 2007, a new consortium of 67 industrial and energy companies announced plans to establish a joint venture company – Fennovoima Oyi – led by E.On (with 34%) - to construct a new nuclear power plant in Finland.
In January 2009, Fennovoima submitted its application to the government for a decision-in-principle, which was granted in May 2010. The company presented three site alternatives but, later in 2009, withdrew Loviisa and in October 2011 decided upon one of two prospective northern sites: Pyhäjoki municipality, rather than Simo which was close to Outokumpu's Tornio steelworks, the largest electricity consumer in Finland. Both are government-defined development areas on the west coast. The Environment Ministry has approved land-use plans and the plant will be built on the Hanhikivi peninsula on the coast of Bothnian Bay, near Pyhäjoki.
The Hanhikivi 1 plant was to be in a net range of 1250-1700 MWe and utilize one of two designs: Areva's EPR with turbine generator from Alstom or Siemens, or Toshiba's version of the 1380 MWe ABWR. (Areva's 1290 MWe Kerena - formerly the SWR-1000, a boiling water reactor, was previously under consideration.) The two were quoted by Fennovoima as up to 1700 MWe and about 1600 MWe respectively at their sites. They were short-listed in July 2011 and commercial bids were received from Areva and Toshiba in February 2012. District heating is to be a by-product. After receiving a construction licence, work was planned to start in 2014, with full operation envisaged by 2020. But as a result of evaluating the bids, in late February 2013 Fennovoima decided to terminate that process and proceed with direct negotiations about the 1600 MWe EU-ABWR with Toshiba.
However, at the same time Fennovoima also started work on a two-stage process to assess whether a mid-sized unit of 1000-1300 MWe would be a better option. After a preliminary assessment of alternatives, the company invited Rosatom to engage in direct negotiations, in parallel with Toshiba, concerning its AES-2006 power plant with VVER-1200 reactor. This new approach was prompted by E.On's departure from the project leaving only the direct stakeholders who will use the power. Fennovoima said it regards mid-sized reactors from Toshiba, Areva and Rosatom as potentially suitable alternatives, and Rosatom was quick to declare its interest. Rosatom is currently constructing five AES-2006 units in Russia, it also has orders to build several such reactors outside of Russia.
In October 2012 E.On announced that it had decided to divest its Finnish interests, including the 34% stake in Fennovoima. The company expressed the hope that the reactor vendor might be willing to invest. However, in February 2013 that stake was taken over by the other shareholders under Voimaosakeyhtio SF, which held all the other shares on behalf of companies representing industry and trade as well as utilities owned by Finnish municipalities and towns - total 67 shareholders.
After two days of intense debate, Finland's parliament in July 2010 approved construction of the TVO Olkiluoto 4 reactor by 120 votes to 72, and one Fennovoima reactor by 121 to 71. It also voted 159 to 35 to increase the planned capacity of the Posiva waste repository (see section on Used fuel disposal below).
Fortum's application for a decision-in-principle on the construction of a new Loviisa 3 unit was rejected by the government in April 2010j.
TVO has bought uranium from Canada, Australia and Africa, had it converted to UF6 in Canada and France, and enriched in Russia. Fuel fabrication has been in Germany, Sweden and Spain.
Fortum predecessor company IVOk contracted for a complete fuel supply service from Russia for the Loviisa plantl.
There have been no uranium mines in Finland, but Areva Resources Finland has applied for a uranium mining claim at Ranua, just south of Rovaniemi in Lapland. Earlier applications for uranium exploration licences in southern Finland were refused in 2007.
Early in 2010, Talvivaara Mining Company Plc announced that it planned to recover 350 tU/yr as a by-product of nickel and zinc production from suphidic black shales (schists) using bacterial heap leaching at Sotkamo in northeastern Finland, over 46 years. The uranium resource is 26,000 tU. In April 2010, Talvivaara applied to the Ministry of Employment and Economy for a license to extract uranium as a by-product, in accordance with the Nuclear Energy Act. The company signed an agreement with Cameco early in 2011 to build a EUR 45 million plant for uranium recovery, to operate from 2013, using solvent extraction. Cameco will take all Sotkamo uranium production to 2027, this agreement being approved by the European Commission in November 2011, and the process licensed by Finland in March 2012. The government approved the company's application for the uranium recovery early in 2012, though it still needs local government and formal STUK approval. In January 2012 STUK said that uranium recovery could be done with minimal radiation release, and the European Commission expressed a positive view of the uranium recovery project.
The heap leach pads at Sotkamo cover 210 ha and after 18 months the ore (0.002%U) is moved to a secondary pad for 36 months. The pregnant liquor (20 ppm U) is first stripped of copper and zinc, then the uranium will be recovered. Hitherto a lot of uranium has remained in the waste stream and has accumulated at the bottoms of nearby lakes, giving rise to concern.
Talvivaara is a shareholder in the Fennovoima project, and in March 2012 increased its stake in it from 10 MWe to 60 MWe (3.3%) by purchasing shares in two regional power companies which are part of Voimaosakeyhtioe, the holding company that owns 66% of the project.
Finland's nuclear waste management program was initiated in 1983, soon after the four reactors started commercial operation. The 1987 Nuclear Energy Act had final disposal as an option, and set up the nuclear waste management fund under the Ministry of Trade and Industrym. The 1994 amendment of the Act stipulates that wastes should be handled wholly in the country (the prior arrangement with Russia for Loviisa used fuel finished in 1996n). Reactor decommissioning is the responsibility of the two power companies separately, and plans are updated every five years. Responsibility for nuclear wastes remains with the power companies until its final disposal.
As of early 2012, over €2 billion had been accumulated in the State Nuclear Waste Management Fund from charges on generated electricity, which account for about 10% of nuclear electricity production costs. The charges are set annually by the government according to the assessed liabilities for each company, and also cover decommissioning.
At Olkiluoto a surface pool storage for spent fuel has been in operation since 1987. This KPA facility has 1270 tonne capacity and is designed to hold used fuel for about 50 years, pending deep geological disposal. An extension to the KPA facility is scheduled for 2011-2014.
At Loviisa, expanded interim storage pools required by expiry of the Russian arrangement to take back used fuel were commissioned in 2000.
TVO and Fortum are responsible for the management and disposal of their low- and intermediate-level operational wastes. An underground repository at Olkiluoto for low- and intermediate-level operational wastes has been in operation since 1992. It is designed to be expanded to take eventual decommissioning wastes. A similar facility at Loviisa was commissioned in 1997.
Used fuel disposal
The final disposal of used nuclear fuel is managed by Posiva Oy, which was set up in 1995 as a joint venture company - 60% TVO and 40% Fortum. It has well advanced plans for a deep geological repository for encapsulated used fuel at the Olkiluoto island in Eurajoki, some 400 metres down in 2 billion-year-old igneous rock. Its plans do not include accommodation for used fuel from Fennovoima's new plant, and Posiva, TVO and Fortum have routinely said they will not accept Fennovoima as a partner. Early in 2012 the government threatened to use its legal authority under the Nuclear Energy Act if necessary to ensure that Fennovoima fuel would be included, but when this did not break the impasse it set up a working group to make recommendations. The working group's January 2013 report said that Posiva and Fennovoima's Hanhikivi should continue negotiation to find a solution for final storage of spent fuel that takes advantage of Posiva's experience. It declined to take a position on whether one or two repositories should be built, but said that the difference in cost would be insignificant.
Making the Olkiluoto bedrock repository bigger to accommodate waste from Hanhikivi would cost about €200 million, whereas building a separate facility would cost in the range €900 million to €1 billion. The upper end of the price estimate applies to scenarios where Fennovoima is not able to employ the knowledge, skills and technology already built up by Posiva over 30 years. Funding to meet the costs would be built up during 60 years of plant operation, making this a minor factor in the plant's economics. Having confirmed the viability of different approaches, subject to licensing and approvals by local and national government, the Energy Market Authority assessment of the report said that "the most expedient and cost-efficient" option would be the expansion of plans for the Olkiluoto facility.
Site selection and environmental impact assessment work was carried out following the Government’s 1983 policy decision on used nuclear fuel. Four locations were investigated by Posiva in some detailo – all were technically suitable, and were covered in Posiva's environmental impact statement for the final repository. In 1999, Posiva applied for a decision in principle for the final disposal facility to be sited at Eurajoki. The decision in principle was issued by the Government at the end of 2000 and ratified by Parliament by a 159 to 3 vote in May 2001. The proposal has strong local community support, and the Eurajoki Council – which had the right to veto the decision – voted 20:7 for it.
Construction on the ONKALO underground rock characterisation facility commenced in 2004 at the Eurajoki site. Research to verify the site selection has been carried out at ONKALO since the beginning of its construction. This will then become the repository site, at a depth of 400-450 metres in the Olkiluoto bedrock.. Posiva applied for a construction licence for the final repository for 9000 tonnes of used fuel from Olkiluoto and Loviisa and the encapsulation plant in December 2012. The operating licence application is expected in 2020, with a view to operation from 2022. Current plans envisage the sealing of the repository in 2120, although this depends on whether the repository accepts waste from reactors built after Olkiluoto 3 and the operational lifetime of those reactors. The estimated total cost of final disposal of used fuel from five reactors is approximately €3 billionp.
Construction of new disposal tunnels will continue progressively in parallel with operation. Posiva proposed that the final size of the repository should be increased from the planned capacity of 6500 tonnes of used fuel to 12,000 tonnes – large enough to accommodate waste from Olkiluoto 4 and the proposed Loviisa 3 – and STUK supported this figure. In July 2010, Parliament voted in favour of an expansion to 9000 tonnes to accommodate the used fuel from Olkiluoto 4q. Posiva claims that it will have no space in the planned repository for fuel from Fennovoima.
Disposal will be based on the multi-barrier KBS-3 systemr, developed by the Swedish Nuclear Fuel and Waste Management Company (SKB). Encapsulation will involve putting 12 fuel assemblies into a boron steel canister and enclosing this in a copper capsule. Each capsule will be placed in its own hole in the repository and backfilled with bentonite clay. The used fuel will be retrievable at every stage of the disposal process.
In January 2010, a TNS Gallup survey (N=1000) commissioned by Finnish Energy Industries (Energiateollisuus) showed that 48% of Finns had a positive view of nuclear power, and only 17% were negative4. The gap between the two was the widest since polling began 28 years earlier. Among women, 33% were positive and 23% negative. Among Green League supporters, 37% were negative, down from 57% five years before, and 21% were positive. The survey also found the highest ever proportion of young people aged 15-24 in favour of nuclear power, at 30%. The percentage of 15-24 year olds registering negative attitudes was likewise the lowest the surveys have ever recorded, at 10%.
In relation to the new Hanhikivi plant at Pyhäjoki, when Fennovoima had started local information campaigns, 51% at Pyhäjoki were in favour of the new plant there and 38% against. In February 2012, soon after the site selection and nearly a year after the Fukushima accident, the numbers were 69% in favour and 25% against, with a steady evolution of opinion in 6 polls over the four years. Regionally the figures in Feb 2012 were 65% in favour and 30% against.
Regulation and safety
Under the Nuclear Energy Act 1987 the Ministry of Trade and Industry (KTM) is responsible for supervision of nuclear power operation and for waste disposals. It is assisted by an Advisory Committee on Nuclear Energy in major matters and also an Advisory Committee on Radiation Protection.
The country's Radiation and Nuclear Safety Authority (STUK) is responsible for regulation and inspection. It operates under the Council of State (effectively the Government), which licenses major nuclear facilities. STUK is administered by the Ministry of Social Affairs and Health, and is assisted by an Advisory Committee on Nuclear Safety in major matters.
Finland is a party to the Nuclear Non-Proliferation Treaty (NPT) as a non-nuclear weapons state. Its safeguards agreement under the NPT came into force in 1972 and in 1995 it came under the Euratom safeguards arrangement. In 1998, it signed the Additional Protocol in relation to its safeguards agreements with both the International Atomic Energy Agency and Euratom.
a. In 2009, Finland's reactors achieved an average annual capacity factor of 98% and the average lifetime capacity factor to the end of December 2009 was 86.4%1 [Back]
b. In 1987, Asea merged with Brown Boveri to become ABB. In 2000, ABB's nuclear business was sold to BNFL and merged with Westinghouse (which was then a subsidiary of BNFL). [Back]
c. TVO was founded in 1969 by a number of companies to build and operate large power plants, supplying the electricity to shareholders at cost. The company is 27% owned by Fortum (see Note d below) and 57% owned by Pohjolan Voima Oy (the major shareholders of which are pulp and paper manufacturers UPM Oyj and Stora Enso Oyj). Owners take their shares of electricity at cost, any unwanted portion being sold by them into the Nordic market. This means that output is effectively contracted to each owner over the life of the plant. The private owners are mostly heavy industry with a high demand for base-load power, and hence low costs are critical for them. [Back]
d. Founded in 1998 from state-owned Imatran Voima (IVO) and listed company Neste, Fortum Corporation is a public listed energy company which is 51% owned by the Finnish government. It owns 27% of TVO (see Note c above), and 43% of Oskarshamn and 22% of Forsmark, both in Sweden. [Back]
e. Although Loviisa 1 & 2 have VVER-440 model V-213 reactors, the plant was extensively modified at the design stage to incorporate Western instrumentation and control systems and containment. [Back]
f. Figures published in 2000 showed that nuclear had very much higher capital costs than the alternatives – €1749/kWe including initial fuel load, which is about three times the cost of a gas plant2. But its fuel costs are much lower, and so at capacity factors above 64% it was the cheapest option. (On the basis of a capacity factor of 91% and interest rates at 5%, operating costs were put at 2.23 Euro cents per kWh (¢/kWh) for nuclear, 2.44 ¢/kWh for coal and 2.63 ¢/kWh for natural gas.) In addition, electricity costs from nuclear generation are less sensitive to fuel price rises than for gas and coal: a 50% increase in fuel prices would result in the electricity cost for nuclear rising about 6%, for coal 21% and for gas 38%. The analysis did not include costs for carbon dioxide emissions, which would make nuclear even more competitive. [Back]
g. In March 2003, tenders were submitted by three vendors for four designs:
- Framatome ANP: European Pressurised Water Reactor (EPR) of 1600 MWe capacity and the SWR-1000 (a BWR) of 1200 MWe.
- General Electric: Advanced Boiling Water Reactor (ABWR) of 1350 MWe.
- Atomstroyexport: VVER-91/99 (V-466) of 1060 MWe.
h. For the planned Olkiluoto 4 and Northern reactors, estimates of gross capacities are given, based on the net figures supplied by the utilities as well as information from vendors. [Back]
i. Fennovoima initially consisted of stainless steel producer Outokumpu, mining and smelting company Boliden, energy utilities Rauman Energia and Katterno Group, and the Finnish subsidiary of Germany-based E.On, which is leading the project. Then in late 2007, the ownership base expanded from five to 63 as electricity consumers sought to insure against future energy cost blowouts. Fennovoima is 66% owned by Voimaosakeyhtiö SF (Power Company SF) and 34% by E.ON Kärnkraft Finland. Voimaosakeyhtiö SF itself is 55% owned by Finnish industrial, retail and services enterprises and 45% owned by local and regional energy companies. All co-owners will be entitled to a pro-rata share of output at production cost from the power plant and will not have to buy in a wholesale market influenced by future gas prices. In December 2010, Fennovoima announced that six utilities and Talvivaara Mining Company became shareholders through Voimaosakeyhtiö SF, bringing the number of shareholders in Fennovoima to 70 (i.e. 69 owners of Voimaosakeyhtiö SF, plus E.ON Kärnkraft Finland). [Back]
j. Fortum was considering five designs, with installed capacity of 1000-1800 MWe, to go online in 2020 or 2021. The designs were: Advanced Boiling Water Reactor (ABWR) supplied by Toshiba; Economical and Simplified Boiling Water Reactor (ESBWR) supplied by GE Hitachi; AES-2006 (with 1200 MWe class VVER reactor) supplied by Atomstroyexport; Advanced Power Reactor 1400 (APR-1400) supplied by Korea Hydro & Nuclear Power (KHNP); and Areva's EPR. The application included the possibility of using the reactor to supply half of the district heating for Helsinki, 80 km away, but the pipeline would have cost up to €1.3 billion. [Back]
k. See Note d above. [Back]
l. In 1998, BNFL supplied five test assemblies that were loaded into Loviisa 1. Following the successful performance of the test assemblies, BNFL won a contract to supply half of the fuel for Loviisa and this arrangement lasted until the end of 2007. There was therefore a seven-year period where Russia was supplying half of the fuel for Loviisa. From 2008, all fuel for Loviisa has been supplied by Russia. [Back]
m. The Ministry of Trade and Industry ceased operations in December 2007 and its responsibilities transferred to the Ministry of Employment and the Economy. [Back]
n. Until 1996, used fuel from Loviisa was returned to the Mayak reprocessing complex near Chelyabinsk in Russia, under a complete fuel cycle service arrangement connected with the supply of reactors by Atomenergoexport to IVO (see Note d above). [Back]
o. Site screening studies commenced in 1983 and preliminary site investigations carried out 1986-1992. Between 1993 and 2000, detailed site investigations and environmental impact assessments were carried out at Romuvaara in Kuhmo, Kivetty in Äänekoski, Olkiluoto in Eurajoki, and Hästholmen in Loviisa. [Back]
p. The estimated €3 billion cost of final disposal assumes 50-year operational lifetimes for Loviisa 1 and 2 and 60-year lifetimes for Olkiluoto 1, 2 and 3. This would equate to about 6,500 tonnes of used fuel. This cost estimate does not include disposal of used fuel beyond these five units, although Posiva has preliminary approval to expand the repository to accept up to 12,000 tonnes of used fuel. [Back]
q. The July 2010 decision by Parliament to allow the capacity of Posiva's planned repository at Eurajoki to be increased to 9000 tonnes of used fuel will mean that the repository can accommodate all existing used fuel, along with that expected to arise from currently operational reactors, plus Olkiluoto 3 and 4.
Posiva had also applied in March 2009 for a further 3000 tonne increase in capacity for used fuel from Loviisa 3, but in April 2010 the government rejected the application to construct Loviisa 3. Meanwhile, Fennovoima was given the go-ahead for a new reactor, but currently has no final disposal route for the used fuel that its reactor would produce. Responding to Parliament's July 2010 decision to allow construction of its proposed new unit, Fennovoima stated: "Parliament requires that the Government contributes to starting assessment and negotiations during 2010 between Posiva, Posiva's owners and Fennovoima regarding the final depositing of spent nuclear fuel."3 [Back]
r. KBS stands for Kärnbränslesäkerhet, meaning 'nuclear fuel safety'. Although SKB has generally stopped referring to the term 'KBS-3', this is the method of final disposal described on its website (www.skb.se) [Back]
