WPRS Benchmarks Workshops 2024

About

The annual Benchmark Workshops of the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS) was co-located with the BEPU 2024 conference and hosted by N.IN.E. (Nuclear and Industrial Engineering) in Lucca, Italy. From 19-23 May 2024, participants of different WPRS Benchmark Activities met, exchanged results and discussed future activities.

Participants unable to join in person could attend the event online via Zoom.

The WPRS Benchmark Workshops addressed benchmarks for neutronics, thermal-hydraulics, fuel performance, and multi-physics aspects of reactor core simulations in LWR, HTGR, SFR, LFR, and other LMFR systems. The workshops also included discussions on the performance of AI and Machine Learning in the domain of single and multi-physics reactor simulations.The event also hosted the CTF User Group Meeting, CTF training, and the second edition of the NEA International School on Simulation of Nuclear Reactor Systems (SINUS).
