The Olkiluoto nuclear power plant [ ɔlkiluɔtɔ ] is a nuclear power plant on the peninsula Olkiluoto on the west coast of Finland in the Eurajoki around 25 kilometers north of the town of Rauma. There is also the nuclear repository at Olkiluoto.

Block I and II - BWR


In Finland, so far ( 2012) four nuclear reactors in operation, two Soviet-designed VVER Loviisa and two boiling water reactors at Olkiluoto. The latter have a net output of 880 and 860 MW and operated by the Company Voima Oyj Teollisuuden (TVO ). Block 1 was used for the first time on July 21, 1978 critical of Block 2 was followed on 13 October 1979. Reactors are since 1979 and 1982 respectively in commercial operation. The two boiling water reactors are of type BWR - 2500th


In October 2012 results were known from a stress test, which the EU could be conducted after the Fukushima nuclear disaster. Among the most critical of nuclear power plants counted it next to the Forsmark nuclear power plant in Sweden, the Olkiluoto nuclear power plant. Thus, for example, would remain the crews in these power plants less than an hour to restore a failed power supply to maintain the absolutely necessary reactor cooling.

Block III - European Pressurised Water Reactor ( EPR)

2003, the tender began over the reactor block 3 Among other things, were the French Areva and the Russian company Atomstroyexport involved in the tender. Atomstroiexport laid plans for a WWER-1000/466 an AES -91 with enhanced security facility for about 800 to 900 million U.S. dollars in the form. The French Areva, however, brought a 1600 -MW EPR reactor type to offer. End of 2003, the contract for Block 3 was then awarded to Areva.

Construction time and cost

This is being built at Olkiluoto since 12 August 2005 by the company Areva NP and Siemens AG ( conventional power plant part). Is the first reactor of this type. The purchase price was originally scheduled turnkey to about 3 billion euros. Already in the first year of construction, however, there were substantial delays ( among others, the foundations were in manufacturing processes to weak concrete);

  • In 2008, the construction costs were estimated at 4.5 billion euros.
  • 2009, the construction costs were estimated at 5.47 billion euros. These costs also legal dispute has now begun.
  • End of 2006, the operating company forecast an operating recording before 2011,
  • In October 2008, the start of operations in 2012 was aimed at.
  • The network synchronization was attempted in June 2010 for 2013.
  • In October 2011, the date was postponed to 2014. The projected construction costs are now 6.6 billion euros are now more than twice as high as the original estimate of 3 billion euros.
  • In July 2012, the operating company announced that in 2014 can not be expected to completion. A new date was not immediately known. Areva announced in December 2012 to a start-up date in 2015. At the same time Areva officials estimated the total cost of 8.5 billion euros.
  • Beginning of 2013 it was stated that the commissioning would move to 2016.
  • Beginning of 2014 the Areva group has squandered an appointment at the new expected completion date should be published. According to experts, to the year 2016 no longer hold.

The Budget Committee of the French National Assembly ( Assemblée nationale ) continued in 2011 a committee, which deals with the massive cost overruns.

In 2004, the European Commission has launched with impetus from Greenpeace an in-depth investigation to check whether the guarantee of France for the aid granted by a syndicate loan of 570 million euros to the generator TVO is compatible with the state aid rules of the EC Treaty. The Commission examined the possibility whether the guarantee for the Areva / Siemens consortium offer has allowed for TVO, so that Areva / Siemens was awarded the contract for the construction of the new nuclear power plant. The case was completed in September 2007, after the investigation came to the conclusion that TVO also on the private capital market would have the 570 million euros can muster. A competitive advantage is not caused by the subsidized loans because these were also included in the same way at competitors' offerings of Areva / Siemens. Also to all the other allegations, no evidence was found.

Six shareholders of TVO carry 25 % of the cost of the nuclear reactor. In addition to the export credit from the French Government a loan from a bank consortium, led by BayernLB, in the amount of 1.95 billion euros at an interest rate of only 2.6 percent interest. For BayernLB were criticized as well as the Bavarian government because the Free State of Bavaria holds half the capital of the Bank.

Block IV

At Olkiluoto, a fourth block is planned. The output of the reactor should be between 1,000 MW and 1,800 MW. In question, among others, an EPR or KERENA ( to March 2009, referred to as SWR 1000) Areva, an Advanced Boiling Water Reactor by Toshiba, a ESBWR by General Electric, a APWR from Mitsubishi, a Korean APR 1400 and a Russian VVER come -1200 / 491 (AES- 2006). It was planned to take the reactor 2016-2018 in operation, now in 2020 aimed at.

Data of the reactor units

In Olkiluoto nuclear power plant has three reactors:
