Approach for domestic procurement of standard material (LSD spike) for isotope dilution mass spectrometry

Ishikawa, Fumitaka; Abe, Tomoyuki; Chiba, Masahiko; Suzuki, Toru ; Kuno, Yusuke; Sumi, Mika

The accountancy analysis of the nuclear fuel material at Plutonium Fuel Development Center of JAEA is performed by isotope dilution mass spectrometry (IDMS). The standard material which called LSD spike is always required for IDMS and indispensable for the facilities where the nuclear fuel material is handled. However, the LSD spike and Pu material has been supplied from foreign countries and those transportation is becoming more difficult recently. The trend of an overseas supply may influence the facilities operation at JAEA in the future. Therefore, research and development of the domestic LSD spike and base material has been performed at JAEA. This report presents the current state and the future plan for the technological development.
