| 摘 要： | 在中国实验快堆（CEFR）中直接测量237Np的裂变截面和俘获截面较困难且误差很大，根据CEFR采用UO2燃料的特点，可通过测量237Np/235U裂变截面比和俘获裂变截面比以获取237Np的相关数据。本文通过分析截面比的测量结果得到237Np的较重要数据，为后期在CEFR上进行237Np嬗变研究和238Pu生产提供了数据支持。

| Abstract: | It is very difficult to measure the fission and capture fission cross sections of 237Np directly in China Experimental Fast Reactor (CEFR) and there are always obvious deviations in the measurement result. Because CEFR uses UO2 as the fuel loading, the related cross section data of 237Np can be obtained through measuring the fission and capture fission cross section ratios of 237Np/235U. By analyzing the result of the cross section ratios, the related cross section data of 237Np were obtained in this paper. It will provide great support for 237Np transmutation and isotope production in CEFR through these data. |
