The Loviisa Nuclear Power Plant (NPP) (Finnish: Loviisan ydinvoimalaitos, Swedish: Lovisa kärnkraftverk) is located close to the Finnish town of Loviisa. It houses two Soviet-designed VVER-440/213 PWR reactors, each with a capacity of 510 MW.
The reactors at Loviisa NPP went into commercial operation in 1977 and 1980 respectively. To comply with Finnish nuclear regulation, Westinghouse and Siemens supplied equipment and engineering expertise. This unorthodox mix of US and Soviet enterprise led to the project developers being given the nickname "Eastinghouse". The plant is operated by Fortum Oyj.
In 1996, the pressure vessel of Unit 1 was successfully heat annealed in order to clear embrittlement caused by neutron bombardment and impurities of the welding seam between the two halves of the vessel.
The operating licence for both units has been renewed for a 50-year lifetime, Loviisa-1 to 2027 and Loviisa-2 to 2030.
Fortum Power and Heat Oy applied to build a third reactor unit, to produce up to 1000 MWt of district heating supply and from 800 - 1,600 MW of electrical generation, which the Finnish government declined on 21 April 2010.
Spent fuel from the reactors were planned to be stored permanently at the Onkalo spent nuclear fuel repository.
In 2014 Rolls-Royce took over the modernisation of safety-related systems for both units from an AREVA-Siemens consortium and the project should be completed by 2018.
