Abstract

1336716 Nuclear power plant BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd and ENGLISH ELECTRIC CO Ltd 18 Dec 1970 [24 Dec 1969] 62815/69 Heading G6C The pressure vessel wall 4 of a gas-cooled reactor forming part of a direct-cycle gas turbine power plant accommodates a pre-cooler 2 and inter-cooler 3 which abstract heat from the gas coolant in its return passage from the turbine to the reactor core. The heat exchangers 2, 3 together with a heat exchanger 5 form an intermediate cooling circuit 1 through which water is circulated by a pump 8 through a non- return valve 9. Heat is abstracted from the circuit 1 by a further circuit 6 through which water is circulated by a further pump (not shown), the heat in circuit 6 being rejected to the sea or atmosphere. Should the power supply to the pumps fail, the water circulation practically ceases so that the water in the heat exchangers 2, 3 boils and at a certain pressure a safety valve 10 opens to vent the steam to atmosphere. At the same time a small pump 12, energized from an emergency source, is started to draw water from an emergency supply tank 11 to replace the loss through the valve 10. Thus the latent heat of vaporization of water is used to provide an emergency cooling system.
