Updated on 24/04/2025

Supercritical pressure water-cooled reactors (SCWRs) have garnered significant interest from the international nuclear community due to their potential for high thermal efficiency and substantial plant simplification. SCWRs are the sole water-cooled reactor among the six GEN-IV concepts. Over the past decade, extensive research activities on SCWRs have been conducted in the nuclear industry. This presentation summarizes and reviews various R&D activities, including experimental studies, analytical methods, and numerical simulations, related to SCWR development. It also identifies future R&D challenges. These efforts contribute to a better understanding of the fundamental thermal-hydraulic phenomena and the improvement of prediction methods.

Dr. Patricia Paviet from PNNL, USA, member of GIF ETWG will facilitate this webinar. 

About the "GIF Education and Training" Webinars

These webinars, organised by the GIF Education and Training Working Group are streamed live monthly. The recordings and slide decks are accessible after the webinar on this website. These webinars cover a very broad range of technical and policy related topics. At the end of 2023 they have been viewed by more than 15000 people (approximately half of the views during the live streams and the other half views being of the archives on the public GIF website). In total, the GIF webinars have reached Generation IV enthusiasts, scientists, and engineers in more than 80 countries.

These webinars are organised and hosted by the GIF Education and Training Working Group (ETWG).
