The amount of adsorption on Ni was about 100 times greater than that on Fe, SS-304 and SS-304/BN.

内容記述 | Tritium contamination of materials used for tritium handling systems becomes a serious problem because an increasing amount of tritium is used for the research and development of thermonuclear fusion reactors. As a first step to develop materials free from tritium contamination, we studied the adsorption and desorption of tritium on Ni, Fe, and various stainless steels. The stainless steels used were SS-304 and SS-304/BN doped with Ce. The measurements were also carried out for passivated ones: namely, SS-304 passivated with electrochemical method (SS-304/P) and SS-304/BN annealed in vacuum at 800℃ for 3 hr (SS-304/BN(H)). In addition, BN discs prepared by chemical vapor deposition were also used for comparison with SS-304/BN(H). The amount of tritium adsorption and that of subsequent tritium desorption with heating considerably varied with samples. The order of the amount was Ni>>(Fe, SS-304, SS-304/BN>>(SS-304/P, SS-304/BN(H), BN). The amount of adsorption on Ni was about 100 times greater than that on Fe, SS-304 and SS-304/BN. The amount of adsorption on SS-304 was about 100 times greater than that on SS-304/P, SS-304/BN(H) and BN. Those results indicate that the adsorption of tritium is dependent to a considerable on Ni content in the subsurface layers of samples. This is supported by the surface analysis with X-ray photoelectron spectroscopy. It is noticeable that little tritium was adsorbed on SS-304/P and SS-304/BN(H).
