裂变核全套中子评价数据为反应堆设计和安全运行、核燃料循环、估算高燃耗反应堆中次锕系核素的产生量及嬗变研究等提供重要的基础数据。本文基于全新的238 Np 中子光学模型势参数，对 n ＋236 Np核反应进行理论分析，并根据 Np 各同位素反应截面系统变化规律，对模型参数进行了调整，最后完成了全套中子数据的更新评价，与 CENDL‐3.1评价结果相比有较明显的改进。

The nuclear data with high accuracy for actinides play an important role in nuclear technology applications ,including reactor design and operation ,fuel cycle ,and estimation of the amount of minor actinides in high burnup reactors and its transmuta‐tion .Based on a new set of neutron optical model parameter of 238 Np and the systematic trend of the cross sections of different Np isotopes ,a full set of 236 Np neutron nuclear data were updated and improved by theoretical calculation . The present result has significant improvements over the data in CENDL‐3.1 .
