The IAEA Regional Training Course No. 5 on the Implementation of Probabilistic Safety Assessment (PSA) for WWER/PWR with Advanced Safety Features started on 16th of July at the Rosatom Technical Academy (Rosatom Tech). The course was organized under the IAEA Technical Cooperation Project RER/9/144: Building Capacity for Infrastructure Development and Safety Assessment of Water Cooled Water Moderated Power Reactor Technology with Advanced Safety Features: the Case of WWER/PWR in cooperation with the ROSATOM State Atomic Energy Corporation.
Currently, there is a great challenge related to building competence and capacity for PSA in Member States because the comprehensive Level-1 and Level-2 PSAs have been done for the vast majority of operating NPPs worldwide and nowadays only periodic revisions to PSAs are being pursued. The PSA performance is now mainly concentrated in design organizations. Therefore, there are fewer opportunities for young engineers to participate in a performance of a real PSA study. The course is aimed to meet the challenges mentioned and contribute to building competence and capacity for Level-2 PSA in the IAEA Member States.
The specialists from Armenia, Belarus, Hungary, Kazakhstan, Slovakia, Lithuania, Poland and Russia came to improve their knowledge on PSA Level-1 and Level-2. From the IAEA side, the course is led by Mr Anthony Patrick Ulses from the IAEA Department of Nuclear Safety and Security together with Mr Andrey Sitnikov from the IAEA Department of Nuclear Energy and Ms Kaliopa Mantcheva from GCR Ltd. (Bulgaria). Ms Irina Kuzmina and Mr Artur Lyubarsky from Atomenergoproekt are experts invited by the Russian side.
The training course combines theory with practical examples of PSA Level-2 applications, interactive sessions and discussions. The purpose of the course was to provide trainees with advanced information on the application of Probabilistic Safety Assessment to advanced WWER/PWR reactor designs currently available on the marketplace. This purpose was to be achieved by providing theoretical information on PSA methodology focusing on Level-2 PSA, conducting discussions and providing practical exercises using the professional PSA software – RiskSpectrum and discussing these in the context of Level-2 PSA.
The participants are expected to improve their capabilities in the preparation and implementation of Level-2 PSA for advanced WWER/PWR reactor designs, as well as received a better understanding in using the PSA results in risk-informed decision making by different stakeholders.
Duration of the training course was 1 week.
