The 7th edition of the International Workshop On Nuclear Data Evaluation for Reactor Applications (WONDER-2026), organized by CEA IRESNE with the help of the CEA Cadarache center, will be held at the Aquabella hotel in Aix-en-Provence, France. The workshop starts on June 29, 2026, at noon and ends on July 3, 2026, at 2 pm. This workshop is the continuation of a series of workshops held in 2006, 2009, 2012, 2015, 2018 and 2023 (see the proceedings of the previous workshops). The main objective of the workshop is to review the current modeling and evaluation methods of nuclear data for reactor applications (both operational and future nuclear installations) and to debate possible areas for improvement. The workshop language is English.
The following topics will be covered:
- Nuclear Data Needs for Reactor Applications
- Microscopic and Integral Nuclear Data Measurements
- Evaluation of Nuclear Data (Theories, Models, Codes)
- Uncertainties and Covariance Matrices (methodology and impact on reactor calculations)
- Processing and Benchmarking
- Thermal Scattering Laws
- Decay Data
- Nuclear Fission, including Prompt Particle Emission and Fission Yields
All detailed information for the workshop is displayed on the General information and important dates page.
