The NEA International Criticality Safety Benchmark Evaluation Project (ICSBEP) and International Reactor Physics Experiments Evaluation Project (IRPhEP) aim at compiling and evaluating respectively critical and subcritical experimental data, and reactor physics experimental data, into standardised benchmarks published within a Handbook. These Handbooks allow scientists to use experimental data for the validation of calculational tools and nuclear data libraries.
The Technical Review Groups for both projects met at the NEA headquarters on 3-7 April 2023, the first in-person meeting in three years. Eight new evaluations were reviewed for the ICSBEP Handbook, and eight potential evaluations in progress for the IRPhEP Handbook were discussed. A task force meeting held during the same week focused on evaluating data collected in the NEA and Radiation Safety Information Computational Center (RSICC) Shielding Integral Benchmark Archive and Database (SINBAD) experiments, with mutual benefit from the sharing of expertise between the SINBAD, ICSBEP, and IRPhEP.
