Leaching behavior of radionuclides from samples prepared from spent fuel rod comparable to core debris in the 1F NPS

Onishi, Takashi ; Maeda, Koji ; Katsuyama, Kozo 

To investigate the leaching behavior of radioactive nuclides in leaching samples comparable to core debris (partially molten ZrO$$_{2}$$/UO$$_{2}$$ between fuel rods) in 1F NPS, the concentration of radionuclides in the leaching solution was measured. Leaching behaviors of actinides (U, Pu, Np) and Cs from the samples were similar to those from spent fuel. Leaching of U and Pu depends on pH in the cooling water of the core debris as predicted from the present thermodynamic database. While, if Mo and Tc are surrounded by zircaloy in the core debris, their leaching amount may become higher by one order of magnitude than those from spent fuel.
