Method of simultaneous chemical decontamination of stainless and carbon steel was developed to reduce dose exposure and to reduce radioactive waste during nuclear power plant decontamination. New chemical decontamination is conducted by using reducing agent containing oxalic acid and oxidizing agent containing permanganate ion repeatedly, then, conducted by using 2000 mg/L of malonic acid. It was confirmed that Co-60 deposited on test pieces, which had been prepared in high temperature high pressure lo...

In order to confirm the effects of gamma-ray irradiation on crevice corrosion behavior of type 304 stainless steel (304 SS), the repassivation potential was experimentally examined in high temperature test seawater (simulated diluted seawater) under gamma-ray irradiation in diluted artificial seawater at temperatures from 323 to 553 K, in conformity to Japanese Industrial Standards (JIS) G 0592. Overall, for high temperatures from 373 to 553 K, the repassivation potentials decreased with increasing chl...
