Xsection 779/20/2023 ![]() 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). ![]() Joint Research Centre (JRC) Sponsoring Org.: USDOE National Nuclear Security Administration (NNSA), Nuclear Criticality Safety Program (NCSP) OSTI Identifier: 1886602 DOE Contract Number: AC05-00OR22725 Resource Type: Conference Resource Relation: Conference: Nuclear Criticality Safety Program (NCSP) Technical Program Review 2022, Held Virtually, Oak Ridge, TN (United States), 15- Related Information: Country of Publication: United States Language: English Subject: 73 NUCLEAR PHYSICS AND RADIATION PHYSICS 97 MATHEMATICS AND COMPUTING 43 PARTICLE ACCELERATORS Nuclear Criticality Safety Program (NCSP) nuclear data GELINA SCALE TSUNAMI TSURFER continuous-energy framework Zr ![]() (ORNL), Oak Ridge, TN (United States) European Commission, Geel (Belgium).
