"New research A new report from Rosatom, the Russian government's highest nuclear authority, shows that there is a grave danger that the stockpile can explode. For Norway the consequences could exceed the fallout from the Chernobyl disaster in 1986, and no one knows how imminent the danger is - if it is a question of years - or hours. "
I’ve read article and discussion under link.
I try to explain briefly.
All submarines have empty nuclear reactors (nuclear fuel is discharged) therefore nuclear explosion is impossible thing.
USA and other states assign money for dismantling of Russian submarines. However Russian functionaries steal the better part of money (former Ministry of Nuclear Industry Eugene Adamov was arrested in the Switzerland for the such reason but Putin coaxed him out - thanks Pr.G.Bush). Russian functionaries divide money between themselves and American partners too. Those initiate worried publications; US government assign more money etc again and again.
