Scope
Under the direction of the Working Party on Nuclear Criticality Safety (WPNCS), the Technical Review Group for the International Criticality Safety Benchmark Evaluation Project (ICSBEPTRG) will co‑ordinate the programme of the International Criticality Safety Benchmark Evaluation Project (ICSBEP) and the development of the ICSBEP handbook and database. These comprise an evaluated set of benchmark specifications derived from experiments performed at various nuclear critical facilities around the world. The benchmark specifications are intended for use by criticality safety engineers to validate nuclear data and calculational techniques used to establish minimum subcritical margins for safe operations with fissile material.
The ICSBEPTRG will also develop a database tool (DICE) to facilitate user access to the ICSBEP benchmarks.
Objectives
The main objective of the ICSBEPTRG is to provide the nuclear community with an evaluated set of benchmark specifications by collecting criticality experiment data from the nuclear criticality laboratories, worldwide. More specifically the objectives are as follows:
Links to other NEA bodies
The ICSBEPTRG will closely co-ordinate its work with other subsidiary bodies of the Nuclear Science Committee (NSC) developing databases of integral experiments. In particular, there will be close links with the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS) Expert Group on Physics of Reactor Systems (EGPRS) and the International Reactor Physics Experiments Evaluation Project Technical Review Group (IRPhETRG); as well as with the International Radiation Shielding Experiments Database (SINBAD). Links will also be maintained with the NSC Working Party on International Nuclear Data Evaluation Co-operation (WPEC) and the Joint Evaluated Fission and Fusion (JEFF) Nuclear Data Library of the Management Board for the Development, Application and Validation of Nuclear Data and Codes (MBDAV).
A key element of the evaluation process is a rigorous analysis of the uncertainties, including quantification of correlations between experiments. There will be strong linkage between the ICSBEPTRG and the WPNCS activities on integral experiment uncertainties and covariance data in criticality safety validation.
