The NEA organised the first International School on Simulation of Nuclear Reactor Systems (SINUS) on 22-23 May 2023. Held online and in Bologna, Italy, the in-person sessions were hosted by the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA), with the support of Newcleo.
Overall 31 participants from 16 countries received comprehensive hands-on training on reactor single- and multi-physics simulations with a specific focus on state-of-the-art best estimate and uncertainty methodologies. This training was preceded by 20 hours of online lectures from experts of the NEA Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS). As part of the training, participants practiced with a state-of-the-art reactor simulation software in Docker environment provided by the NEA Data Bank and the US Radiation Safety Information Computational Center (RSICC). Participants presented their results to the WPRS experts during the Uncertainty Analysis for Modeling of Light Water Reactors (UAM-LWR) session of the WPRS Benchmarks Workshops, which provided an opportunity to network with the international experts community.
The SINUS training material development was led by North Carolina State University (NCSU), and software licenses were granted by NCSU and RSICC. The European Commission’s ENEN2Plus project provided mobility fund to cover travel expenses for 20 participants.
