Russia's nuclear plants, with 31 operating reactors totalling 21,743 MWe, comprise:
4 first generation VVER-440/230 or similar pressurised water reactors,
2 second generation VVER-440/213 pressurised water reactors,
9 third generation VVER-1000 pressurised water reactors with a full containment structure, mostly V-320 types,
11 RBMK light water graphite reactors now unique to Russia. The four oldest of these were commissioned in the 1970s at Kursk and Leningrad and are of some concern to the Western world. A further Kursk unit is under construction.
4 small graphite-moderated BWR reactors in eastern Siberia, constructed in the 1970s for cogeneration (EGP-6 models on linked map).
One BN-600 fast-breeder reactor.
