<p>PROBLEM TO BE SOLVED: To provide a nuclear reactor water injection system and nuclear facilities capable of supplying cooling water in a suppression pool into a reactor pressure vessel continuously for a long period of time.SOLUTION: A nuclear reactor water injection system 3 includes: a feedwater pipe 22 supplying cooling water into a reactor pressure vessel 5; a suppression pool 20; and a condensed water storage tank 30. The nuclear reactor water injection system 3 further includes a water injection pump 40 pumping up the cooling water stored in the suppression pool 20 to the feedwater pipe 22; a condensed water circulation pipe 50 returning the cooling water in the condensed water storage tank 30 to the condensed water storage tank 30 again; and a condensed water circulation pump 55 that is a pump pumping the condensed water flowing in the condensed water circulation pipe 50. The condensed water circulation pipe 50 is configured so that the cooling water from the condensed water storage tank 30 cools a bearing 48 of the water injection pump 40.</p> |
