摘要
文章描述用双裂变电离室和ＨＰＧｅｒ谱仪测量辐照后燃料元件中和质量的原理及方法，并给出秦山核电站考验元件中和质量测量结果。
The content of and in tested fuel element of Qinshan nuclear power plant are de-termined by double fission ionization chamber and HPGe r spectrometer, respectively. The experi-mental principle and method are described in the papar. The plutonium samples are made into a se-ries of electroedposit targets and irradiated by thermal nertron in research reactor of China Insti-tute of Atomic Energy. Corrections of fission by fast neutron and neutron flux densitychange in target are considered. The quantity of Pu needed in experiment is about l μg. The mea-surement accuracy is 2 % approximately.
