POWER PLANT FOR NUCLEAR-POWERED VESSEL Russian patent published in 2000 - IPC

FIELD: shipbuilding; power plants for nuclear submarines, nuclear-powered vessels and ships and floating atomic power plants. SUBSTANCE: power plant includes water-cooled reactor plant and power supply sources including turbogenerators, emergency diesel-generator and/or storage battery and/or storage battery and thermoelectric generator which is arranged in hermetic container outside pressure hull of submarine in reservoirs of outer hull filled with sea water or inside pressure hull. It is provided with two closed heat-transfer loops with working non-freezing liquid used as heat-transfer agent. First loop supplying heat to hot junctions of thermoelectric generator includes heat exchanger connected to first loop of reactor plant and second loop discharge the heat from cold junctions of thermoelectric generator includes heat exchanger mounted in sea water main. Provision is made for operation of thermoelectric generator both in submerged and surface positions of submarine with no limitation in time. EFFECT: enhanced efficiency and reliability; enhanced nuclear safety; continuous unattended servicing for 10 to 15 years. 3 cl, 1 dwg
