Advanced Assessment Methods for Nuclear Power Plant Safety

Successful first APAL workshop held on the state-of-the-art of RVP integrity assessments

After a first year of intensive research activities, the APAL consortium invited the community working on safety assessments of reactor pressure vessels (RPV) to a state-of-the-art workshop. The hybrid event was kindly hosted by the Paul Scherrer Institute (PSI) in Switzerland. During the two days (30th & 31st of April), the 13 European partners and 2 international partners from Japan and USA presented an overview on the procedures currently applied to the integrity assessment of RPVs subjected to PTS loading. The extensive state-of-the-art covered weld residual stress (WRS), warm pre-stress (WPS), thermal-hydraulic (TH) analysis, probabilistic PTS analysis and relevant statistical tools. Furthermore, the consortium presented its selection of LTO improvements that have an impact on PTS and that will be assessed during the upcoming research activities in APAL.

More than 100 participants from 20 countries and 40 international companies made this event a great success. The organisers are especially proud to have generated interest from the community working on safety assessments of reactor pressure vessels. The APAL consortium would like to thank all participants and presenters for providing a fruitful experience, as well as the hosting organisation PSI, especially Mr Dr Diego Mora for the great organisation. The partners are looking forward to welcoming at least as many participants to the next APAL workshop in the summer of 2023!
