The major installations of the Russian nuclear weapons complex are the ten 'closed nuclear cities' managed by the Russian Federation Ministry for Atomic Energy (Minatom). These facilities design, maintain and dismantle weapons and produce fissile materials and weapon components. It is estimated that 732,000 people live in the closed cities, and approximately 127,000 are employed in the key nuclear enterprises.
