Loviisa Nuclear Power Plant
Encyclopedia
Loviisa Nuclear Power
Plant (NPP) , is a nuclear power plant located close to the Finnish city of Loviisa
. It houses two Soviet-designed VVER-440/213
PWR reactors, each with a capacity of 488 MW.
The reactors at Loviisa NPP went into commercial operation in 1977 and 1980 respectively. In order 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
.
The pressure vessel of Unit 1 has been successfully heat annealed in 1996 in order to clear embrittlement caused by neutron bombardment and impurities of the welding seam between the two halves of the vessel.
The operating license for both units has been renewed for a 50 year lifetime, Loviisa-1 to 2027 and Loviisa-2 to 2030.
A third reactor was proposed for the Loviisa site by Fortum Power and Heat Oy. The single reactor unit could produce up to 1000 MWt of district heating
supply and from 800 - 1,600 MW of electrical generation. On 21 April 2010, the Finnish government declined the application by Fortum to build a new reactor at Loviisa.
Nuclear power
Nuclear power is the use of sustained nuclear fission to generate heat and electricity. Nuclear power plants provide about 6% of the world's energy and 13–14% of the world's electricity, with the U.S., France, and Japan together accounting for about 50% of nuclear generated electricity...
