摘要
Abstract
During the shutdown of nuclear power plant units,the use of forced oxidation processes to dissolve and remove activated corrosion products from the primary circuit is a crucial part of overhaul source term control.Micro-nano bubble solutions can generate high concentrations of hydroxyl radicals,whose strong oxidative properties have been widely applied in the cleaning industry.This study focuses on spinel-like simulated corrosion products to investigate the effect of forced oxidation processes coupled with micro-nano bubble technology on the dissolution of corrosion products.The results showed that the addition of 10 mg/kg hydrogen peroxide to weakly alkaline primary circuit water had almost no effect on the dissolution of spinel corrosion products.When the pH was acidic,the addition of hydrogen peroxide could enhance the dissolution rate of spinel corrosion products.More strikingly,when hydrogen peroxide was added and micro-nano bubbles were injected into the acidic pH environment,the dissolution rate of spinel corrosion products was increased by more than twice compared with the same conditions.The research results provide an important reference for optimizing the source term control strategy of activated corrosion products in the primary circuit during nuclear power plant overhauls.关键词
