損傷した燃料等から滞留水へ放射性核種が移行したふるまいに関して、滞留水に含まれる放射性核種の濃度を燃料組成により規格化して検討した。滞留水への移行しやすさは、Csに比べてSe, I, Hが大きく、Srが同程度、TRUはごく小さかった。

Transport behavior of radionuclides from the damaged fuel into the accumulated water was investigated by normalizing their concentration contained in the water with the fuel composition. Transport of nuclides to the water was greater for Se, I and H compared with Cs whereas equivalent for Sr, and much smaller for TRUs.
