Rosatom Tech successfully completed the Regional Training Course on PSA Applications and Risk Informed Decision Making

Rosatom Tech successfully completed the Regional Training Course on PSA Applications and Risk Informed Decision Making

The ninth Regional Training Course on Probabilistic Safety Assessment (PSA) Applications and Risk Informed Decision Making (RIDM) was accomplished successfully from 11 to 15 November in the Moscow Office of Rosatom Technical Academy. This training course was a closing event for the IAEA technical cooperation project RER9144 “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”.

Nowadays capacity building in the area of PSA and RIDM in countries that are currently operating NPPs with water-cooled water-moderated reactors is an essential task. The comprehensive PSA-1 and PSA-2 studies were performed at the design and commissioning stages for most of the operating NPPs around the world. Thus, there are ever fewer opportunities for specialists to take part in a real PSA study. The training course placed a special emphasis on the best practices in the area of PSA applications, as well as on discussion of available national experiences and challenges in this area.

The training course was attended by nineteen specialists from eleven countries (Armenia, Belarus, Bulgaria, Czech Republic, Hungary, Kazakhstan, Poland, Russia, Slovakia, Slovenia, Turkey). The programme lectures were provided by the IAEA representative – Mr Shahen Poghosyan (Department of Nuclear Safety and Security, IAEA) and invited experts: Mr John Preston (nuclear safety advisor, Ableith Consult, UK) and Mr Ivan Vrabnic (safety analysis engineer, APOSS d.o.o., Croatia). Russian leading experts in the field of PSA from Rosatom Technical Academy and JSC Atomenergoproekt shared their experience with participants and contributed to the successful compilation of the training programme.

The local and invited experts presented up-to-date information on various PSA applications (including design evaluation and plant modifications), as well as integrated risk informed decisions making process. A significant part of the training programme was allocated for discussions and practical exercises.

For reference:

The IAEA technical cooperation project RER9144 “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” has been implemented in Rosatom Tech since 2016. The project objective is to ensure the sustainable and safe use of nuclear power and relevant national nuclear infrastructure development in the interested Member States through education and training. Regional training within the project was dedicated to the safety assessment of pressurized water reactors, neutronic and thermohydraulic calculations by means of computer codes.
