Scope
The IRPhE Technical Review Group will co-ordinate the programme of the International Reactor Physics Experiments Evaluation (IRPhE) Project and the development of the IRPhE Handbook and database. These comprise of an evaluated set of benchmark specifications derived from experiments performed at various reactor facilities around the world. The benchmark specifications are primarily intended for use by reactor analysts to validate computational methods along with the associated basic data libraries.
The IRPhE Technical Review Group will also steer the development of a database tool to facilitate user access to the IRPhE benchmarks.
Objectives
The IRPhE Technical Review Group will provide the nuclear community with an evaluated set of benchmark specifications derived from experiments performed at reactor facilities, worldwide. More specifically the objectives are as follows:
Interactions
The IRPhE Technical Review Group will closely co-ordinate its work with other subsidiary bodies of the Nuclear Science Committee (NSC) developing and using databases of integral experiments. In particular, there will be close links with the Technical Review Group for the International Criticality Safety Benchmarks Evaluation Project (ICSBEPTRG). The ICSBEP programme is co-ordinated through the ICSBEP Technical Review Group, which reports to the Working Party on Nuclear Criticality Safety (WPNCS). In addition, there will also be close links with the International Assay Data of Spent Nuclear Fuel Database (SFCOMPOTRG), co-ordinating the database of measured nuclide concentrations of spent nuclear fuel, comprising operational histories and design data; . and with the Technical Review Group for the Shielding Integral Benchmark Archive and Database (SINBADTRG) co-ordinating shielding assessments under the Shielding Integral Benchmark Archive and Database (SINBAD).
A key element of the evaluation process is a rigorous analysis of the uncertainties, including quantification of correlations between experiments. There will be collaboration between the IRPhETRG and the activities listed previously in the area of uncertainty analysis methods. Additionally, communication will be maintained between the IRPhETRG and both the WPRS Expert Group on Reactor Systems Multi-Physics (EGMUP) as well as the Expert Group on Physics of Reactor Systems (EGPRS).
The group may be solicited to interact with the project on data preservation and quality assurance within the NEA Framework for Fuel and Material Testing (FIDES-II).
The IRPhETRG will also invite and co-operate with experts from non‑member countries, as needed.
Deliverables:
**[The International Reactor Physics Experiments (IRPhE) project was established in 2004. Until February 2017, this project was managed by the Expert Group on Reactor Physics and Advanced Nuclear Systems (EGRPANS) and reported to the Working Party on Scientific Issues of Reactor Systems.]
