热化截面库SabDEP制作与热化截面插值方法

加工生成了基于ENDF/B Ⅶ及其评价方法的新热化ACE(ACompactENDF)截面库SabDEP（工程物理系热化截面库），包括轻水、重水、Be、石墨、H/Zr和Zr/H共6种材料，每种材料含6个温度点。对SabDEP库进行了微观截面比对验证和积分计算验证，重水的截面相对于原来生成的截面有很大改进。在清楚ACE文件结构基础上，对热化截面开展了温度插值方法研究，取得了很好的插值结果。

Process of ACE Formatted Thermal Scattering Data SabDEP and Research on Thermal Data Interpolation

Based on latest release of version Ⅶ of the Evaluated Nuclear Data File (ENDF/B-Ⅶ) and evaluation method, a new ACE (A Compact ENDF) formatted thermal neutron scattering data SabDEP (S(α,β) of Department of Engineering Physics) was developed including H in light water, D in heavy water, Be, graphite, H/Zr and Zr/H with six temperatures for each material. The validation was done by comparing data with downloaded and integral ones. With a clear knowledge of thermal ACE structure, temperature related interpolation research was done, and a good result was achieved.
