Under the guidance of the Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC), 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. The NEA WPRS Expert Group on Reactor Fuel Performance (EGRFP) performs specific tasks associated with fuel performance aspects of present and future nuclear power systems, with a focus on normal operating conditions.

A key objective of the group is to help identify, evaluate and preserve experimental data necessary for developing separate-effect models and integral fuel rod codes and updating validation databases. In this context, the Expert Group monitors, steers and supports the International Fuel Performance Experiments (IFPE) data collection. This working paper on the experimental data requirements for fuel performance modelling was initiated and developed in service of the EGRFP’s stewardship of the IFPE.
