FIELD: nuclear power plants for spacecraft.
SUBSTANCE: proposed spacecraft nuclear power plant has converter reactor, radiation shield, folding cooler-radiator with heat-transfer system units, and lithium as coolant. This power plant is provided with heat-transfer apparatus. Lithium is used as coolant for heat-transfer apparatus and eutectic sodium-potassium alloy, for cooler-radiator. Heat-transfer apparatus provides for introducing coolant characterized in low melting point into folding cooler-radiator circuit.
EFFECT: minimized energy required to transfer folding cooler-radiator from starting (folded) to orbital (unfolded) position.
