Under the guidance of the Working Party on Scientific Issues of Reactor Systems (WPRS), the expert group performed specific tasks associated with radiation transport and shielding aspects of current and future nuclear systems and accelerator-based irradiation facilities.
Nuclear systems considered, including but not limited to the following:
The expert group also had the option to consider radiation transport and shielding for some other types of facilities, including:
The technical information was generally derived from a combination of direct experimental evidence and/or the results of theoretical benchmark analyses (including sensitivity/uncertainty analysis) using validated modelling methods. In either case, the availability of suitable experimental data was a fundamental requirement. A key objective of the group was, therefore, to help identify, evaluate and preserve this type of experimental data. In this context, the expert group monitored, steered and supported the continued development of the International Radiation Shielding Experiments Database (SINBAD), in co-operation with the United States’ Radiation Safety Information Computational Centre (RSICC).
The expert group reported to the Working Party on Scientific issues in Reactor Systems (WPRS) and maintained close links with the International Reactor Physics Experiments (IRPhE) and International Criticality Safety Benchmark Evaluation (ICSBEP) projects. It also worked in co-ordination with the Joint Evaluated Fission and Fusion File (JEFF) NEA Data Bank project and with the Shielding Aspects of Accelerators, Targets and Irradiation Facilities (SATIF) community of accelerator shielding specialists. Links were also established with the Codes and Standards Working Group (CSWG) of the Multilateral Design Evaluation Programme (MDEP).
13th Meeting of the task force on Shielding Aspects of Accelerators, Targets and Irradiation Facilities (SATIF-13), 10-12 October 2016, Dresden, Germany.
The expert group meets once a year, with additional meetings in support of particular activities (e.g. SINBAD, SATIF).

To ensure reliable modelling of neutron physics within a state-of-the-art transient code, the neutron kinetics part of such a code should be based on the full-scale calculation of the space-time neutron kinetics equations without use of the diffusion approximation and spatial homogenisation.
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) performs specific tasks associated with reactor physics aspects of present and future nuclear power systems.
The Expert Group on Shielding Aspects of Accelerators, Targets and Irradiation Facilities (SATIF) dealt with the various aspects of the modelling and design of accelerator shield systems and radiation facilities.
The Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS) studies the reactor physics, fuel performance, and radiation transport and shielding in present and future nuclear power systems.
