The next annual Benchmarks Workshops of the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS) will be hosted by Nuclear Operations & Facilities and the Department of Engineering Physics at McMaster University, and located in Hamilton, ON, Canada.
The event is mainly supported by the Safety Licensing Program of Conexus Nuclear Inc. (formerly CANDU Owners Group), on behalf of its four Canadian domestic funding members (Bruce Power (BP), Canadian Nuclear Laboratories (CNL), New Brunswick Power (NBP), and Ontario Power Generation (OPG)), and three international funding members (Societatea Nationala Nuclearelectrica S.A. (SNN), Romania, Korea Hydro and Nuclear Power Company (KHNP), Korea, and CNNP Nuclear Power Operations Management Company Ltd. (CNNO), China).
From 11 to 15 May 2026, 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), lead-cooled fast reactors (LFRs), and molten-salt reactors (MSRs).
Two topical sessions will take place during the workshops:
The fourth edition of the NEA International School on Simulation of Nuclear Reactor Systems (SINUS) will be co-organised with the Workshops.
The workshops will take place at McMaster University, in Hamilton, ON, Canada.
Registered users will be given access to a dedicated NEA SharePoint page with detailed agendas and all meeting material.
