Siberian Chemical Combine

The Siberian Chemical Combine () was established in 1953 in Tomsk-7 now known as Seversk, in the Tomsk Region as a single complex of the nuclear technological cycle for the creation of nuclear weapons components based on fissile materials (highly enriched uranium and plutonium). It is a subsidiary of TVEL (Rosatom group).
History.
The Siberian Chemical Combine played an important role in the Soviet Union's nuclear weapons program. The facility produced plutonium and highly enriched uranium (HEU), and fabricated warhead components using produced plutonium and HEU.
As the Cold War came to an end, the Siberian Chemical Combine's HEU production ceased and the last plutonium production reactor at the facility was shut down in 2008. Although production has halted, the facility remains a major site for storage and handling of weapon-usable materials and nuclear weapon components.
Presently, the facility supplies Russia's low enriched uranium fuel needs and enriches reprocessed uranium for foreign customers. The facility is one of the largest sites that stores low and intermediate level nuclear wastes from reprocessing with more than 30 million cubic meters stored via deep-well injection.

The complex is based on four plants:
