| 内容記述 | Fuel loss and environmental contamination by tritium permeation through structural materials are critical issuesfor the establishment of a fusion DEMO reactor. In this study, the effectivity of a chromium oxide layer formedon reduced activation ferritic/martensitic steel F82H as a tritium permeation barrier and its stability undersimulated solid/liquid breeder blanket conditions have been investigated. A uniform 100-nm-thick chromiumoxide layer was formed by heat treatment at 710 °C for 5 min in 50% argon-50% hydrogen mixed gas with theflow rate of 200 standard cubic centimeter per minute. After exposure to simulated solid breeder blanket con-ditions, an iron oxide layer and a spinel-type iron-chromium oxide layer formed. In the case of a liquid breederblanket condition, the chromium oxide layer partly lost at 500 °C for 100 h. The chromium oxide-formed sampledecreased deuterium permeationflux by a factor of up to 150. The permeation reduction efficiency deterioratedafter exposure to a solid breeder blanket condition due to a change of the chromium oxide layer. However, thechromium oxide formation would play a role to reduce hydrogen isotope permeation even after reduction of theoxide layers | |||||
