[2A03] Behavior of Radiolytic Gas in Zeolite Bed under Gamma-ray Irradiation

*Takafumi Motooka1, Isao Yamagishi1 (1. JAEA)

Keywords:gamma-ray, irradiation, zeolite, radiolysis, gas

Mixtures of zeolite IE96 and artificial seawater (ASW) were poured in cylindrical tubes, and irradiated by Co-60 gamma-rays. In the case of a zeolite bed which was fully immersed in ASW, the zeolite bed level increased slightly(1.8%) and an ASW phase formed onto the bed. The ASW level increased with the irradiation dose. In the case of a partial immersion, which simulates a drained zeolite vessel, the zeolite bed level was un-changed (0.0%).
