PSA Level 1 and Applications


Read disclaimer

Probabilistic Safety Assessment (PSA) is an effective tool to enhance plant safety, and to operate nuclear facilities in the most efficient manner. However, a PSA that is to be used as a day to day tool for decision making at NPPs has to reflect the actual design and operational features of the plant as accurately as possible, it must be of high quality and has to be subject to strict QA processes. Since the early 80s the IAEA has made a considerable effort to support the development of technical capabilities for PSA in Member States, to write technical procedures for carrying out PSA, and to assist the Member States in reviewing PSA though its IPSART Service (International PSA Review Team). Additionally, current efforts are being devoted to support and promote the appropriate use of PSA methods and results in decision making at the nuclear power plants.

The purpose of this workshop is to provide the participants with basic training on key issues in PSA level 1. The second part of this workshop is dedicated to presentations on low power level PSA and some PSA applications in the design and operational areas.
