critical hydrogen G-value hydrogen radiolysis
Hydrogen evolution by radiolysis of water in a sealed vessel has been studied with Co-60 gamma source to develop evaluation method for hydrogen evolution amount to transfer and store radioactive materials. Experiments were carried out by changing ratio of gas phase volume to liquid phase volume to consider effects on hydrogen production amount from pure water at room temperature. Obtained results were (1) G-value became smaller and equilibrium pressure increased when ratio of gas phase volume to liquid...

Chemical Decontamination Clearance Decommissioning Malonic Acid Oxalic Acid
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...

Artificial Seawater Chloride ion Crevice corrosion High Temperature Nuclear Power Plant Repassivation Potential Stainless Steel
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...
