Microstructure in a cast stainless steel used for a PLR pump casing cover in a BWR was investigated by atom probe tomography and nanoindentation testing. Ferrite phase decomposition and G-phase precipitation were no t observed in the as-received PLRP casing cover. Thermal aging and solution treatment were carried out on the as-received PLRP casing cover and an unused model alloy of cast stainless steel. The ferrite phase decomp osition and G-phase precipitates in the thermal aged model alloy disappeared af...
