Moscow, Russian Defense minister Sergei Shoigu on Thursday released additional details about the fire aboard a specialized submarine that killed 14 submariners in the Barents Sea on Monday.

The fire erupted in the submarine's battery compartment and later spread, said Shoigu.

"The nuclear reactor on the vessel is completely isolated and unmanned. All the necessary measures were taken by the crew to protect the reactor, which is in complete working order," Shoigu told Russian President Vladimir Putin.

"In our case, this is not just possible but obligatory," Shoigu said of the submarine's repair. "Right now, we are assessing how long it will take, how much work there is, and how we can carry it out."
