Russia is world's first to decommission commercial uranium-graphite reactor

Rosatom's Experimental Demonstration Center for Decommissioning of Uranium-Graphite Nuclear Reactors has accomplished the decommissioning of a commercial uranium-graphite nuclear reactor, the center said in a press release.

Rosatom's Experimental Demonstration Center for Decommissioning of Uranium-Graphite Nuclear Reactors has accomplished the decommissioning of a commercial uranium-graphite nuclear reactor, the center said in a press release.

"This is a unique event: such a project has never been accomplished in world practice before," the report said.

Experimental Demonstration Center specialists supported by leading research centers of the Russian Academy of Sciences rapidly developed unique technologies for the world\'s first safe decommissioning of a uranium-graphite nuclear reactor, it said.

A state commission is planned to accept the works on September 25.

The dual-purpose uranium-graphite nuclear reactor EI-2 was put into service in 1958 at the Siberian nuclear power plant in the Tomsk-7 restricted zone (currently Seversk) in the Tomsk region. It was the first nuclear power plant in the Soviet Union and the first commercial NPP with an initial output of 100 megawatt. Later on ADE-3, ADE-4 and ADE-5 plutonium production uranium-graphite reactors increased its output to 600 megawatt. The EI-2 reactor was shut down in 1990, the shutdown of ADE-3 followed in 1992 and the other two reactors were stopped in 2008.

The last two reactors were shut down under a Russian-U.S. agreement to terminate the production of war-grade plutonium.

The Experimental Demonstration Center for Decommissioning of Uranium-Graphite Nuclear Reactors is an enterprise of Rosatom state corporation's unit of the last stage of service life. It is focused on the decommissioning of atomic energy sites. For instance, the enterprise designs and introduces technologies for the safe decommissioning of nuclear power units, sources of radiation and radioactive waste storage sites.
