Comparison of cross-section libraries in benchmark calculations

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


Integral data have been used for decades to test differential evaluated nuclear data and computational methods. In recent years an intensive international effort led to the preparation of the International Handbook of Evaluated Criticality Safety Benchmark Experiments. Unfortunately, the handbook does not include information on measured integral data other than critical masses. The Cross Section Evaluation Working Group Benchmark Specifications contain information on other integral data such as the leakage out of some metallic spheres and on central reaction rate ratios for more assemblies. Two extensive data tests have been reported recently by Los Alamos National Laboratory and Oak Ridge National Laboratory. In this paper we compare the performance of the ENDF/B-VI.3, JEF-2.2, and JENDL-3.2 evaluated cross-section files.
