METHOD FOR CHEMICAL DECONTAMINATION PRIOR TO DEMOLITION OF REACTOR

摘要

PROBLEM TO BE SOLVED: To provide a method for chemical decontamination prior to the demolition of a reactor which makes it possible to shorten the time for treating drainage anticorrosives in the water of a pressure suppression pool.;SOLUTION: The method for chemical decontamination prior to the demolition of the reactor is used, which has: a system decontamination process of conducting chemical decontamination inside a reactor pressure vessel by using a reducing decontamination liquid and an oxidizing decontamination liquid supplied from a chemical decontamination installation; a process of supplying a waste liquid containing the drainage anticorrosive in the pressure suppression pool into the reactor pressure vessel; and an anticorrossive treatment process of giving decomposition treatment to the drainage anticorrosive in the waste liquid supplied into the reactor pressure vessel.;COPYRIGHT: (C)2009,JPO&INPIT
