NEA-1765 IRPHE2022/23HANDBOOK

IRPHE2022/2023-HANDBOOK.

The purpose of the International Reactor Physics Experiment Evaluation (IRPhE) Project is to provide an extensively peer-reviewed set of reactor physics-related integral data that can be used by reactor designers and safety analysts to validate the analytical tools used to design next-generation reactors and establish the safety basis for operation of these reactors. This work of the IRPhE Project is formally documented in the “International Handbook of Evaluated Reactor Physics Benchmark Experiments”, a single source of verified and extensively peer-reviewed reactor physics benchmark measurements data.

The IRPhE Handbook is available on DVD or by online access. Either may be requested by completing the package request form: https://www.oecd-nea.org/tools/ierequest/start/package/NEA-1765%2517

The evaluation process entails the following steps:

1. Identify a comprehensive set of reactor physics experimental measurements data,

2. Evaluate the data and quantify overall uncertainties through various types of sensitivity analysis to the extent possible, verify the data by reviewing original and subsequently revised documentation, and by talking with the experimenters or individuals who are familiar with the experimental facility,

3. Compile the data into a standardized format,

4. Perform calculations of each experiment with standard reactor physics codes where it would add information,

5. Formally document the work into a single source of verified and peer reviewed reactor physics benchmark measurements data.

The International Handbook of Evaluated Reactor Physics Benchmark Experiments contains reactor physics benchmark specifications that have been derived from experiments that were performed at nuclear facilities around the world. The benchmark specifications are intended for use by reactor designers, safety analysts and nuclear data evaluators to validate calculation techniques and data. Example calculations are presented; these do not constitute a validation or endorsement of the codes or cross-section data.

The 2022/2023 edition of the International Handbook of Evaluated Reactor Physics Benchmark Experiments contains data from 170 experimental series that were performed at 57 nuclear facilities. A total of 166 of the 170 evaluations are published as approved benchmarks. The remaining four evaluations are published as draft documents only. The cover of the handbook shows the IPEN/MB-01 reactor in Brazil. This edition of the handbook now includes 21 benchmark evaluations containing experiments contributed from this versatile facility.
