| abstract | PROBLEM TO BE SOLVED: To provide a method for recovering nuclear fuel debris capable of recovering nuclear fuel debris accumulated at the bottom of a nuclear reactor which has been destroyed by an accident at a nuclear power plant and has a complicated structure. The method for recovering nuclear fuel debris according to the present invention is a method for recovering nuclear fuel debris 6 deposited in a reactor storage vessel 2 or a reactor pressure vessel 4, so that the first pressure is maintained. Inject the carbonated water 8 so that the nuclear fuel debris 6 is immersed in the controlled reactor storage vessel 2 or the reactor pressure vessel 4, or it already exists in the reactor containment vessel 2 or the reactor pressure vessel 4. A liquid injection step of adding a substance that makes the liquid carbonated water 8, a foaming step of foaming the carbonated water 8 after the liquid injection step, and a nuclear fuel debris 6 that floats due to adhesion of bubbles generated in the carbonated water 8 after the foaming step. It has a recovery step of recovering. [Selection diagram] Fig. 1 |
