A Russian nuclear-powered submarine undergoing repairs at a shipyard has caught fire, but its reactor had long been shut off and poses no danger of radiation leaks, officials say.
The submarine Tomsk was being repaired at a shipyard near the city of Vladivostok when the fire broke out on Monday, the defence ministry said in a statement cited by Russian news agencies.
"Radiation in the area of the emergency incident on board the Tomsk is normal, the reactor had been out of operation since the submarine began undergoing repairs in 2011," a source in the far east fleet told RIA Novosti.
The fire was put out and all staff evacuated, with no injuries, said the defence ministry statement.
"According to preliminary data, the reason for the fire was violation of welding procedures," it said.
