Abstract

Abstract

The oxidation and purification of the primary coolant loop is of great importance in control-ling the dose rate during the outage.In this paper,the effects of pH value,H₂O₂ and H₂ concentration on the migration of activated corrosion products were discussed theoretically.A new method for the shutdown oxy-genation operation,characterized by low pH,low H₂ and introducing oxygen densely at suitable amount,was proposed based on the operation experience of Daya Bay nuclear power station.
