ABSTRACT=CENDL-3.2 and ENDF/B-VIII.0 refer to the latest version of CENDL and ENDF/B evaluated nuclear data library, respectively. To examine the applicability the libraries to high temperature reactors (HTRs), HTR-10 benchmark calculations are conducted by adopting CENDL-3.2, ENDF/B-VIII.0 and ENDF/B-VII.1 library. The calculated results are compared with experimental results. As indicated from the comparison, the results of ENDF/B-VIII.0 shows the optimal consistency with experimental results, and CENDL-3.2 outperforms ENDF/B-VII.1. A semi-quantitative analysis method, based on the sensitivity result, is employed to assess the effect of the cross-section change to k_eff. As revealed from the further calculations and analyses, the difference between cross-section of C-12 (n, γ) channel primarily causes the inconsistent performance of CENDL-3.2 and ENDF/B-VIII.0 on the benchmark.
