$$gamma$$分析による短半減期核種の除染係数(DF)のホットデータ取得を目的として、短冷却の高速実験炉「常陽」照射済燃料を用いた晶析基礎試験を実施した。今回測定できたもののうちCs以外の各核種(Pu, Ru-106, Ce-144, Pr-144等)については、U試験等の結果から期待される100程度のDFが得られたほか、これまでのホット試験では除染できなかったCsについても、CsがPuとの複塩を形成せず除染できる条件がありうることが示唆された。

For the purpose of obtaining DFs of the short-life FPs by $$gamma$$ analysis in the hot experiment, fundamental test of crystallization process was carried out using Fast Experimental Reactor "JOYO" irradiated fuel. In this experiment, DFs of nuclides analyzed by $$gamma$$ analysis except Cs (Such as Ru-106, Ce-144, Pr-144) and Pu were evaluated to be about 100. It was suggested that there is the condition in which Pu-Cs double salt does not be formed, although DF of Cs had been very low in the past experiments because of forming Pu-Cs double salt.
