Abstract In this study, the nuclear-data adjustment method based on the continue-energy cross sections has been implemented for the fast reactor. The technique of nuclear-data adjustment based on the sensitivity/uncertainty analysis has been widely applied for the fast reactor to improve the nuclear-data accuracy. The previous researches towards nuclear-data adjustment were implemented to the multigroup cross-section libraries. As improvement, the nuclear-data adjustment based on the continue-energy cross-section library and corresponding Monte-Carlo code has been implemented. The Generalized Linear Least Square method was used to determine the relative adjustments for different kinds of isotope and cross sections within different energy ranges. For adjusting the continue-energy cross-section library, corresponding continue-energy cross-section perturbation model has been proposed and applied in this study. As application, the experiment measurements provided on the JOYO and ZPPR facilities have been used for the nuclear-data adjustment. Observed from the numerical results, very efficient improvement of the nuclear-data accuracy can be satisfied through the nuclear-data adjustment for the continue-energy cross sections.

基于快堆连续能截面库的核数据调整

摘要 本研究对快堆实施了基于连续能截面的核数据调整方法。基于敏感性/不确定性分析的核数据调整技术已广泛应用于快堆，以提高核数据的准确性。之前对核数据调整的研究是在多组横截面库中实现的。作为改进，实现了基于连续能量截面库和相应的蒙特卡罗代码的核数据调整。广义线性最小二乘法用于确定不同能量范围内不同同位素和横截面的相对调整。用于调整连续能量截面库，相应的连续能量截面微扰模型已被提出并应用于本研究。作为应用，JOYO 和 ZPPR 设施上提供的实验测量已用于核数据调整。从数值结果观察，通过对连续能截面的核数据调整，可以非常有效地提高核数据的精度。
