Before being submitted to the ENDF library, files were processed and tested for performance by running benchmark calculations. ![]() In response to this, the Oak Ridge National Laboratory (ORNL) formed a Nuclear Criticality and Data group more ยป which performed ND experiments, data analysis, and evaluations to produce ENDF files for the ND libraries as identified in the NCSP Five-Year Plan. More than two decades ago, the US Nuclear Criticality Safety Program (NCSP) established a Nuclear Data (ND) task which encompassed experiments and evaluations. In some cases, the cross-section evaluations of those libraries were found to be deficient in describing criticality benchmarks accurately. Nuclear criticality modeling and simulations rely on the quality of the existing evaluated nuclear data libraries such as Evaluated Nuclear Data File (ENDF)/B, the Joint Evaluated Fission and Fusion (JEFF) nuclear data library, or the Japanese Evaluated Nuclear Data Library (JENDL).
