Plutonium produced by the ADE-2 reactor and its counterparts, ADE-4 and ADE-5 in Seversk, has not been used in the weapons program since 1994. Instead, it was stored on site in the form of plutonium oxide. During this period the three reactors produced 18 tonnes of weapon-grade plutonium. This material will be consolidated at Zheleznogorsk. ADE-4 was shut down in April 2008, ADE-5 - in June 2008.
Russia no longer produces weapon materials
The last Russian plutonium production reactor, ADE-2 at Zheleznogorsk, was shut down on April 15, 2010 at noon local time (04:00 UTC) as planned. This event marks the end of production of weapon-grade fissile materials in Russia.
