The next annual Benchmarks Workshops of the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS) will be hosted by the Department of Engineering of the University of Cambridge in collaboration with the Cambridge Nuclear Energy Centre, University of Cambridge, United Kingdom.

From 30 June to 4 July 2025, participants of the different WPRS Benchmark Activities will meet, exchange results and discuss future activities. The WPRS Benchmarks Workshops will address benchmarks for neutronics,  thermal-hydraulics, fuel performance, and multi-physics aspects of reactor core simulations in light-water reactors (LWRs), high-temperature gas-cooled reactors (HTGRs), sodium-cooled fast reactors (SFRs), and lead-cooled fast reactors (LFRs). The event also features a dedicated session on the performance of AI and Machine Learning in the domain of single and multi-physics reactor simulations based on the work of the Task Force on Artificial Intelligence and Machine Learning for Scientific Computing in Nuclear Engineering. Two new activities on the reactor multiphysics of light-water cooled, small, modular reactors (LW-SMRs) and on reactor pressure vessel fluence simulations for LWRs are anticipated to hold their kick-off meetings.

The third edition of the NEA International School on Simulation of Nuclear Reactor Systems (SINUS) will be co-located with the Workshops.

The 32nd International Meeting On Reactor Noise (IMORN-32) will be held the week after the WPRS Benchmarks Workshops from 7-9 July 2025 in Cambridge too.
