Hydrogen gas generation from cement solidified form by -ray irradiation

Nakayama, Takuya ; Kawato, Yoshimi; Meguro, Yoshihiro

Radioactive combustible wastes generated in JAEA are incinerated and the incinerated ash obtained will be solidified with cement. Hydrogen gas may be generated from the cement solidified form by radiolysis. Therefore, we tried to determine G-value for hydrogen gas generation from the cement solidified form. The G-value is needed to evaluate safety of storage of the cement solidified form. An artificial cement solidified form of incinerated ash was irradiated with 2.7 kGy -ray from a $^{60}$ Co source for 1 hour. G-value calculated using the absorbed dose, the weight of the form and the amount of hydrogen generated was 1.22 0.18 molecule/100 eV.
