摘要： PURPOSE:To decrease an operator's exposure by installing an insoluble impurity removing device to the outside of a pressure suppression pool. CONSTITUTION:A suction piping 25 is installed in the pressure suppression pool 4. This piping 25 is connected to a valve 26 installed on the outside of the pool 4. A strainer 29 which is the insoluble impurity removing device is installed between this valve 26 and an emergency core cooling pump 27 via a piping 28. The insoluble impurities in the pool 4 stick to the strainer 29 and the accumulation of the insoluble impurities in the cool 4 is prevented when a pump 27 is started. The insoluble impurities in the pool 4 stick to the strainer 29 and are thereby removed when a circulation operation is carried out by using a test line 20 and, therefore, the water quality of the pool 4 is improved. Further, the operator is capable of removing the strainer 29 and cleaning foreign matter therefrom without entering the pool 4, since the strainer 29 is installed on the outside of the pool 4. The operator's exposure is thereby decreased.
