MOSCOW - Block 4 of Russia's Beloyarsk nuclear power station in the Urals mountains was switched off on Sunday following a 'false' response by the safety system, a subsidiary of state nuclear corporation Rosatom said. It said the block was halted at 09.15 (0415 GMT). 'The stoppage was carried out under a routine algorithm,' Rosenergoatom said in a statement, adding the radiation background at the station and surrounding areas was in line with usual levels. The plant was opened in 1964. Last month, a Russian nuclear power plant northwest of Moscow turned off three of its four generating units after a transformer short circuited. They have returned to operation since.
