Benchmark Activities on Reactor Single- and Multi-Physics of the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS)
Ongoing Reactor Single- and Multi-Physics Benchmark Activities

Scope

The Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS)  and its Expert Groups co-ordinate benchmark activities on reactor single- and multi-physics. The benchmark activities serve the WPRS objectives: 

  • to provide members with up-to-date information, preserve knowledge on, and develop consensus regarding reactor physics, thermal-hydraulics, radiation transport and dosimetry, and multi-physics aspects associated with nuclear power systems, aimed at providing the technical underpinnings of assessment of system performance and safety.
  • to provide advice to the nuclear community on the developments needed to meet the requirements (data and methods, validation experiments, scenario studies) for the assessment of different reactor systemsprovide training and educational material to the nuclear community, to assist with developing future technical expertise within member countries. Workshops will be held on WPRS benchmarks.
  • to provide training and educational material to the nuclear community, to assist with developing future technical expertise within member countries. 

 The activities address the the following reactor types:

  • Current fleet of light-water and heavy water reactors (LWRs/HWRs) as well as present generation of fuel designs.
  • Evolutionary and innovative LWRs/HWRs along with advanced and/or accident tolerant fuel designs.
  • Next generation of reactor systems including water cooled small modular reactors (SMRs), micro-reactors, high temperature gas cooled reactors (HTGR) as well as advanced fast spectrum systems including sodium fast reactors (SFRs) and molten salt reactor systems (MSRs).
  • Accelerator driven (sub-critical) and critical systems for waste transmutation as well as fusion systems.

Annual Benchmarks Workshop

The WPRS organises an annual WPRS Benchmarks Workshop (typically 1 week with 2 parallel tracks) in which the benchmark teams exchange on the status of their simulations and discuss benchmark specification updates.
