The compatibility of Cu-alloy (CuCrZr) with high-temperature high-pressure water, and its corrosion behavior was evaluated. Static corrosion tests in hydrogen-dissolved water were conducted up to 500hr. Weight change of specimens was smaller than those in deaerated water. Specimen surface was sponge-like with crystals on surface.
