Method for carrying out fuel debris in boiling water nuclear power plant

摘要

PROBLEM TO BE SOLVED: To provide a method capable of carrying out fuel debris of a boiling water reactor in a short time.SOLUTION: In the present invention for solving the problems, in the carry-out method of fuel debris in a boiling water nuclear power plant, a cutoff material is injected into a reactor pressure vessel, and then the fuel debris molten in the reactor pressure vessel is carried out in the state in which water is filled in the reactor pressure vessel. An injection port is disposed in a pipe connected to the inside of the reactor pressure vessel, the cutoff material is injected through the injection port.
