Iron-chromium-aluminum (FeCrAl) alloys such as APMT (advanced powder metallurgy tubing) are candidate materials to replace zirconium for the light water reactor fuel cladding. This alloy meets requirements be a material more tolerant of high-temperature accidents than current alloys. One concern is that use FeCrAl may result in an increase tritium presence coolant compared design. The aim resea...

A multilayer composite ceramic membrane was prepared by depositing a nano-scale layer of SiO2 on top of a modified porous alumina support by chemical vapor deposition (CVD) method. The modification of the support was carried out by adding a graded layer of Al2O3 (γ-alumina phase), using sol-gel method. An optimized temperature of 700 K for intermediate layer calcination was gained by XRD analys...

Hydrogen permeation reduces a material’s properties and increases the risk of brittle fracture, which causes potential safety hazard. A workpiece’s hydrogen resistance could be improved by improving its surface integrity through processing. This paper studies low-alloy steel’s in production reactor, using electrochemical cathodic hydrogen-charging method to carry out experiments. After specimen...
