COMPLEX DECOMMISSIONING METHOD FOR NUCLEAR FACILITY

摘要

A complex decommissioning method for a nuclear facility is disclosed. The complex decommissioning method for a nuclear facility including a reactor pressure vessel and biological shield concrete, which includes a cavity in which the reactor pressure vessel is positioned, comprises the steps of: cutting and expanding the inner wall of the cavity; providing, inside the cavity, a cutting device for cutting and dismantling the reactor pressure vessel; fixing the reactor pressure vessel inside the cavity by using a fixing device; and using the cutting device so as to cut and dismantle the reactor pressure vessel fixed inside the cavity.
