Abstract

PURPOSE: To improve sagety by providing an emergeney circulating water pump in parallel with a main circulation pump and connecting the former with an emergency Diesel-engine generator.
CONSTITUTION: An emergency circulating water pump 34 is connected to a cooling pipe 32 of a condenser 14 through a check valve 37, and is located in parallel with a main circulation pump 29 which is connected with the cooling pipe 32 through a check valve 38. The pump 34 can be driven by an emergency Dieselengine generator 39 through a motor 35. In emergency where the pump 29 cannot operate due to loss of power source, the generator 39 is automatically started so that the pump 34 is driven to feed cooling water to the cooling pipe 32, pressure rise in the condenser 14 is prevented, operation of release valve 28 of a low-pressure turbine 13 is prevented, and discharge of steam to the outside is prevented.
