In a surprise announcement by US nonproliferation officials, Russia’s state nuclear energy corporation Rosatom is expected to switch off one of Russia’s last three remaining plutonium producing reactors on Sunday in the closed Siberian nuclear city in of Seversk, which has been producing weapons-grade plutonium for four decades.

In the heyday of the Cold War, Russia operated 14 plutonium production reactors, all but three of which have been shut down. These three – two in Seversk and one in Zheleznogorsk, near Krasnoyarsk – remained in operation, but recent movements within the Russian government have fast tracked the long stalled shut down projects – at least for Seversk.

For the 17 years following the collapse for the Soviet Union and the fragmentation of its mammoth nuclear weapons machine, the reactors produced plutonium that the Kremlin neither needed nor wanted.

But the reactors could not be closed, and plutonium was still produced, because the reactors have been the primary source of heat and power to the bitterly cold regions along the Tomsk River in Central Siberia, where no equivalent utility sources had been built.

More worrisome still is that places to put the plutonium are scarce. In 2005, then Minister of Atomic Energy Alexander Rumyantsev announced that the Mayak Fissile Materials Storage Facility – CTR’s longest running project, which was developed to store 50 tonnes 0f weapons-grade plutonium and 200 tonnes of weapons grade uranium – would be scaling back on its intended capacity.
Rumyantsev announced that the facility, that had been under construction with US funds since 1993, would be housing no uranium and only 25 tons of plutonium that were to come from disassembled warheads.
