N1 - Funding Information:
It is well-recognized that PSA is potentially subject to a number of limitations, some methodological and some resource-driven. Ongoing work in several Member States is aimed at addressing these limitations to improve analysis realism, better characterize uncertainties, and better support Integrated Risk-Informed Decision Making (IRIDM). Recognizing the considerable effort in these activities, and supported by extrabudgetary funds from the USA, the IAEA initiated a project in 2018 to identify challenges and opportunities in advanced PSA approaches and applications. The specific topics addressed by the project are:

N2 - To build on the marked benefits of probabilistic safety assessment (PSA) in support of Integrated Risk-Informed Decision Making (IRIDM), IAEA Member States have been spending considerable efforts to improve PSA approaches and extend applications of existing approaches. In 2018, the IAEA started a project supported by USA extrabudgetary funds aiming to collect current experiences regarding these activities and to develop a related technical document that might support future updates of related IAEA Safety Guides on PSA. The PSA topics considered in the scope of this technical document are dynamic PSA, combination of hazards, use of non-permanent equipment, use of Level 2 PSA in support of the development of Severe Accident Management Guidelines (SAMG), Level 3 PSA, the incorporation of ageing aspects in the PSA model, and software reliability of digital instrumentation and control systems and modelling within PSA. This paper summarizes the challenges and the opportunities identified through the IAEA project. Despite the disparity of topics, a number of general lessons regarding technical, infrastructure, and decision support challenges are highlighted.
