Abstract

This invention relates to a nuclear reactor plant which includes a nuclear heat source ( 12 ), and a cooling system ( 10 ). The cooling system ( 10 ) includes at least two cooling circuits ( 26 ), each of which includes a plurality of coolant chambers ( 18 ) each having an inlet ( 40 ) and an outlet ( 42 ), the coolant chambers ( 18 ) being arranged around the nuclear heat source ( 12 ). The cooling system ( 10 ) further includes pump means ( 52 ) for pumping coolant to and from the coolant chambers ( 18 ), the volumetric capacity of the coolant chambers ( 18 ) being sufficiently large such that, when in a passive mode, the temperature of a water coolant in the coolant chambers ( 18 ) will remain below boiling point for at least eight hours.
