Forsmark Nuclear Power Plant is a nuclear power plant in Sweden, and also the site of the Swedish Final repository for radioactive operational waste.

[edit] Reactors

Forsmark NPP has three Boiling water reactors:

  • Unit 1 (968 net MWe) was first connected to the grid on 5 June, 1980, and commenced commercial operation on 10 December, 1980. It has two turbo alternators.
  • Unit 2 (964 net MWe) was first grid connected on 15 December, 1980 and commenced commercial operation on 7 July, 1981. It is a twin of Unit 1.
  • Unit 3 (1,155 net MWe) was first grid connected on 3 March, 1985 and commenced commercial operation on 21 August, 1985. It is a later design with one turbo alternator.

[edit] Waste disposal

Forsmark is the proposed site for the long-term burial of all spent fuel from Swedish nuclear power reactors, using the KBS-3 process. The new site will be located next to the already existing final repository for radioactive operational waste, but the two will not be connected with each other.

[edit] July 2006 incident

On 25 July 2006 one reactor was shut down after an electrical fault.[1][2] According to the Swedish Nuclear Power Inspection authority SKI the incident was rated 2 on the International Nuclear Event Scale. According to Lars-Olov Höglund, a former construction chief at Vattenfall, it is the most serious nuclear incident in the world since the Chernobyl disaster and it was pure luck that prevented a meltdown.[3] Both the SKI and the safety chief of Forsmark power plant disagree with that opinion and state that the incident was serious but the description provided by Höglund was incorrect and there was no risk of a meltdown.[4] However SKI also writes about the failing safety system that "finding out that safety functions proved to be linked together in a delicate way is according to SKI extremely serious".[5]

[edit] April 1986

On April 27, 1986 unusually high levels of radiation were detected in workers' clothing at this plant, prompting concerns of a radiation leak. No leak was found, however, and the radiation was determined to have originated from Chernobyl, whose reactor had exploded the previous day. Chernobyl is approximately 1,100 km from this powerplant.
