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...

BWR ECP HWC JANTI Guideline SCC
Water environment improvement (ex. Hydrogen Water Chemistry (HWC)) is carried out for Stress Corrosion Cracking (SCC) mitigation in some of BWR plants. Japan Nuclear Technology Institute (JANTI) has the guideline on the inspection programs based on effectiveness of environmental SCC mitigation technique for BWR core internals. The guideline provides the crack growth rate (CGR) under HWC. Although CGR is defined by ECP (electroch emical corrosion potential), a dealing of evaluation of ECP and the HWC avail...

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...
