Forsmark NPP has three Boiling water reactors:
West of Forsmark Nuclear Power Plant, there is the static inverter of HVDC Fenno-Skan.
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.
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 subsequently determined to have originated from Chernobyl, where a reactor had exploded the previous day. Chernobyl is approximately 1,100 km from this power plant.
Detection of rise of environmental radioactivity at Forsmark was crucial in leading Soviet authorities, originally attempting to cover up the disaster, to admit that a nuclear incident had taken place in Pripyat. This, in turn, was the immediate trigger for evacuation of Pripyat, which Soviets had considered unnecessary for more than 36 hours following the explosions.
On 25 July 2006, one reactor was shut down after an electrical fault. 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. 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.
Lars-Olov Höglund has been involved in a personal legal dispute with Forsmark Nuclear powerplant for several years.
However, SKI also writes about the failing safety system in that finding out that safety functions proved to be linked together in a delicate way is extremely serious.
In January an internal report made by a few employees at Forsmark who were concerned over a "degrading safety culture" was leaked to media who ran an extensive story on it. In the storm following the report the Forsmark CEO chose to resign. Forsmark was already under way to implement a 60-point program designed to improve safety culture, designed shortly after the event in July 2006.
