Synthesis report on C/E validation and nuclear data trends

Abstract

This deliverable of the EC SANDA project “Supplying Accurate Nuclear Data for Energy and non-Energy Applications” (H2020 Grant Agreement number 847552) addresses Task 5.2 “Validation studies using existing experiments”, Subtask 5.2.2 “𝐶𝐶/𝐸𝐸 validation and trends”.

It compiles the findings of Deliverables 5.7 and 5.8 on validation of JEFF nuclear data files across reactor, shielding and criticality benchmarks as well as a validation of fission product nuclear data against MINERVE/CERES pile oscillation experiments, that was also envisaged in the task. As a result of the systematic benchmark calculations performed for each JEFF release, the needs for nuclear data improvement or reconsideration are synthesized, with particular indication of the benchmarks identified as useful for checking the performance of specific isotopes, reactions and energy ranges. Finally, new applications that should be addressed in future validation suites are proposed.
