Zusammenfassung:	PURPOSE:To enable the recovering of heat of a blow water of a steam evaporator discharged without being utilized sufficiently and heat of a thermal effluent of a condenser effectively at a nuclear power plant. CONSTITUTION:Blow water 11 from a steam generator 3 is flashed with a flash tank 14 to make a saturated steam 15, which is introduced into a reproducer 17 of a suction type heat pump and a thermal effluent 13 produced by cooling the steam with a condenser 8 is introduced into an absorption type heat pump evaporator 19. Both devices are used as drive heat source for an absorption type heat pump. Water 24 to be heated is introduced into an absorber 20 and then, into a condenser 18 of the absorption type heat pump to obtain a higher temperature hot water 24'.
