硝酸ウラニル結晶の精製を目的とした静止系での発汗現象を用いた結晶精製試験を実施した。液体不純物として存在するCsと超ウラン元素の精製速度係数を評価した。これらの除染係数は、時間と共に増加したものの、240分後には概ね一定になることがわかった。

For the purpose of further increasing decontamination performance, the crystal purification experiments by sweating phenomenon were carried out with uranyl nitrate hexahydrate crystals in the static system. The purification rate coefficients of Cs and transuranium elements as liquid impurities were evaluated using these experimental data. These decontamination factors had a tendency to increase with time and were kept virtually constant by 240 min.
