Explosion-bonded metal joint has been used at the spent nuclear fuel reprocessing plant in Japan. The metal joint is made of zirconium, tantalum and R-SUS304ULC. And the radiolytic hydrogen is known to be generated in the spent nuclear fuel solution. Also, tantalum is known to be highly susceptible to hydrogen embrittlement. Therefore, evaluating the radiolytic hydrogen absorption behavior of metal joint in nitric acid solution (HNO
) is essential. In this study, immersion tests were conducted on tantalum in nitric acid solutions under -ray irradiation to evaluate its radiolytic hydrogen adsorption behavior. Results showed that the radiolytic hydrogen absorbed in zirconium near the Zr/Ta interface. But, hydrogen embrittlement was not observed in tensile test under -ray irradiation. The reason was considered that the radiolytic hydrogen was trapped at the surface of the zirconium as hydride.
