Under the guidance of the Nuclear Science Committee (NSC), the expert group deals with the activities associated with the certification of experimental data and benchmark models along with establishing the processes and procedures for using the data and benchmark models for validation of modelling and simulation tools and data.
The expert group liaises closely with other relevant NEA working parties and expert groups, including those operating under the guidance of the Committee for Technical and Economic Studies on Nuclear Energy Development and the Fuel Cycle (NDC) and the Committee on the Safety of Nuclear Installations (CSNI), to ensure that the respective programs are complementary and to provide advice and support where required and undertake common work where appropriate.
The goal of the Committee for Technical and Economic Studies on Nuclear Energy Development and the Fuel Cycle is to provide authoritative, reliable information on nuclear technologies, economics, strategies and resources to governments for use in policy analyses and decision-making.
The expert group provides advice to the Working Party on Scientific Issues of Reactor Systems (WPRS) and the nuclear community on the scientific development needs (data and methods, validation experiments, scenario studies) of sensitivity and uncertainty methodology for modelling of different reactor systems and scenarios.
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.
