Abstract
PURPOSE: To enable the design and the maintenace and inspection easy, by means of cooling suppression water by a heat exchanger while the decay heat which is transfered to a suppression pool from a core.
CONSTITUTION: In a case when the pressure of a reactor becomes lower and the driving pump of a fturbin becomes not generated a prescribed rated flow quantity, the cooling water is poured by means of actuating a low pressure pouring booster pump 441, and a low pressure pouring pump 44 or a low pressure spray booster pump 4 and low pressure spray pumps 41. Even when the temp. of suppression pool water becomes higher, effectiveness NPSH of the low pressure pouring pump 44 or the low pressure spray pump 4 is subjected to be increased for keeping the prescribed property by means of cooling the suppression pool water by the heat exchanger 9 while th decay heat which is transfered to the suppression pool from the core is removing. The design of a pump becomes easy from the result of being reduced by the temp. of an absorbing point.
