燃料デブリ中のアクチノイドを高精度かつ迅速に分析するために、誘導結合プラズマ質量分析装置(ICP-MS/MS)の利用を検討している。本研究では、アクチノイド同重体の干渉除去に向けた基礎的知見を得るために、ICP-MS/MSのセル内で生じるアクチノイドイオンと反応ガスとの気相反応を調査し、その反応性に関するパラメータとして反応定数の評価を試みた。

Ultratrace analysis technique is important to understand fuel debris in nuclear reactor core after sever accident. Ion-molecule reactions of actinides ($$^{237}$$Np, $$^{241}$$Am and $$^{244}$$Cm) in a reaction cell were measured by inductively coupled plasma mass spectrometry (ICP-MS/MS). These nuclides are included in fuel debris. A gas-phase ion-molecule reaction model has been developed to simulate the gas phase reactions in the reaction cell. The results of model simulation are good agreement with the flow rates dependences of experimental data accurately.
