质谱法测定低浓缩燃料组件燃耗

The Burnup Determination of Low Enriched Fuel Assembly by Mass Spectrometry

Abstract: This paper refers to something about the burnup measurement of irradiated low enriched fuel assembly in high flux engineering test reactor (HFETR), including sample cut, dissolution, separation, determination of mass spectrometry, and uncertainty analysis etc.. The results accord with the theoretical calculation value.
