METHOD FOR REPLACING NUCLEAR REACTOR PRESSURE VESSEL

摘要

PROBLEM TO BE SOLVED: To propose a method for replacing a nuclear reactor pressure vessel enabling full safety in carrying in/out operations of the nuclear reactor pressure vessel when the nuclear reactor pressure vessel installed inside a reactor building is replaced. SOLUTION: In this method for replacing a nuclear reactor pressure vessel 4 including a process for changing the attitude of the nuclear reactor pressure vessel 4 from the erected state to the laid state or vise versa near a reactor well 6, a pool gate 16 partitioning the reactor well 6 and an equipment pool 8 is taken out and the attitude of the nuclear reactor pressure vessel is changed.
