APAL will conduct three workshops and a final seminar during the project lifetime open to consortium partners, students, members of the Advisory Board and interested end-users such as NPP owners, suppliers and regulatory bodies.

End-user workshop

Ahead of the forthcoming 'end-user workshop', experts involved in the APAL project are defining a best-practice guide for the deterministic and probabilistic assessment of advanced Pressurized Thermal Shock (PTS) analysis for integrity assessment of RPVs. The guide will incorporate improved methodologies and provide recommendations for assessing various types of uncertainties in thermo-hydraulic (TH) analysis, propagation of uncertainties throughout the entire PTS assessment, human factor, WRS solutions, WPS methods, etc. These are essential aspects for Long-Term Operation (LTO) of nuclear power plants. The draft best-practice guide will be distributed to registered participants before the end-user workshop and will summarise the experience accumulated by the professionals in advanced PTS analysis, serving as a valuable resource for nuclear power plant owners, suppliers, regulatory bodies, and other stakeholders. The end-user workshop takes place to inform potential users, foster discussions, and collect feedback to refine the guidance. This workshop will take place from 14th-15th May 2024 in Warsaw, Poland.

Advanced workshop

The 'advanced workshop', based on a training programme developed in the second half of the project, will focus on advanced methods and LTO improvements for RPV integrity analyses with focus on pressurised thermal shock (PTS) loading. The intermediate progress made in the project will be made visible, regarding thermal-hydraulic best-estimate plus uncertainty analyses, as well as deterministic and probabilistic fracture mechanics analyses. This workshop took place from 11th-12th May 2023 in Ljubljana, Slovenia.

State of the art workshop

During the 'state of the art workshop' experts provided an overview the procedures currently applied to the integrity assessment of RPVs subjected to PTS loading. Moreover, the current state of the art for LTO improvements was presented. The participants got familiar with ordinary software tools and methods (deterministic and probabilistic) used for thermal hydraulics and fracture mechanics calculations. The aim is a better understanding of the different steps of PTS assessment and their technical background. The basics of probabilistic, thermal hydraulics, system behaviour and fracture mechanics were taught in comprehensive lessons.This workshop took place from 30th-31st March 2022 in Switzerland.
