Under the guidance of the 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 working party also studies the uncertainties associated with the modelling of these phenomena, particularly the modelling of reactor transient events.

The next meeting of the WPRS and its expert groups will be held in person at the NEA Offices from 17- 21 February 2025. Please note the WPRS week will be co-located with the meetings of the Working Party on Materials Science Issues in Nuclear Fuels and Structural Materials (WPFM). 

Participation in an expert group and the WPRS requires nomination by your country, or an invitation or support by your country's delegation and confirmation by the Chairs. If you are not a delegate, then your registration will need to be confirmed by the NEA Secretariat.

The event is restricted to participants from NEA member countries, the European Commission, and the International Atomic Energy Agency.

Participation in the meetings requires mandatory registration:  Register your participation 

All meeting material will be made available on the following password-protected working area: MyNEA SharePoint.
