Soviet naval reactors

Soviet naval reactors have been used to power both military and civilian vessels, including:

• Nuclear submarines:
  • Attack submarines.
  • Cruise missile submarines.
  • Ballistic missile submarines.
• Nuclear icebreakers:
  • Soviet icebreaker Lenin
  • Arktika-class icebreakers
  • Taymyr-class icebreakers
• Russian floating nuclear power stations:
  • Akademik Lomonosov
• Nuclear cruisers:
  • Kirov-class battlecruisers
• Merchant ship:
  • Sevmorput
• Command ship:
  • SSV-33 Ural

They have included both pressurized water reactors and a relatively few liquid metal fast reactors.

OKBM Afrikantov has been the primary designer of naval reactors for the Soviet/Russian Navy for more than 60 years.
