Russia’s nuclear regulator Rostekhnadzor has granted a five-year licence extension for Unit 2 of the Smolensk nuclear power station, state-owned nuclear corporation Rosatom said in a statement.
Rosatom said the move will allow the reactor to remain in service for 45 years, or 15 years beyond its original design life.
There are three operating RBMK light-water graphite reactor units at Smolensk, in western Russia. They began commercial operation in 1983, 1985 and 1990.
