The latest version of Shielding Integral Benchmark Archive and Database (SINBAD), distributed by the NEA and Radiation Safety Information Computational Center (RSICC), includes over 100 shielding benchmark experiments covering fission reactor shielding (48 benchmarks), fusion blanket neutronics (31), and accelerator shielding (23) applications.
Interest in using SINBAD shielding benchmarks was expressed by nuclear data communities in the scope of several WPEC subgroups, and within the Joint Evaluated Fission and Fusion (JEFF) and European Fusion File (EFF) projects. Progress in SINBAD compilations slowed down in recent years and a new kick-off of this activity would be beneficial to assess and respond to the expectations and needs of different nuclear data communities. Multiple challenges and objectives will be considered including to:
WPEC Subgroup 47 (SG47) works in close coordination with other NEA activities such as WPRS Expert Group on Radiation Transport and Shielding (EGRTS), WPEC SG45, SG46, Collaborative International Evaluated Library Organisation (CIELO) Pilot Project and the JEFF project, where the work could be used to guide the evaluations. Feedback from these groups on the specific needs and the use of Shielding Integral Benchmark Archive and Database (SINBAD) data is expected. SINBAD evaluation work shall be tightly coordinated with the interest of SG46 on Efficient and Effective Use of Integral Experiments for Nuclear Data Validation. Past experience in integral benchmark evaluations from the International Criticality Safety Benchmark Evaluation Project (ICSBEP), the International Reactor Physics Experiment Evaluation (IRPhE) Project and SINBAD will be valuable.
Under the guidance of the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS), the Expert Group on Physics of Reactor Systems (EGPRS) will perform specific tasks associated with reactor physics aspects of present and future nuclear power systems.
The International Handbook of Evaluated Reactor Physics Benchmark Experiments (IRPhE) contains reactor physics benchmark specifications that have been derived from experiments that were performed at various nuclear facilities around the world.
The NEA's nuclear data evaluation co-operation activities involve the following evaluation projects: ENDF (United States), JENDL (Japan), ROSFOND/BROND (Russia), JEFF (other Data Bank member countries) and CENDL (China) in close co-operation with the Nuclear Data Section of the International Atomic Energy Agency (IAEA).
The Collaborative International Evaluated Library Organisation (CIELO) Pilot Project, working under the auspices of the WPEC Subgroup 40 (SG40), was established to generate complete evaluations for a selection of the most important isotopes for parameters in nuclear technologies: U-235, U-238, Pu-239, Fe-56, O-16 and H-1 with the aim of improving the accuracy of the data and resolving previous discrepancies in the overall understanding.
