The International Atomic Energy Agency’s (IAEA’s) Operational Safety Review Team (OSART) programme assists Member States in strengthening the safety of their nuclear power plants during commissioning and operation, by comparing actual practices with IAEA safety standards.
In January 2018, EDF Energy’s Torness Nuclear Power Station welcomed an OSART mission with the aim to assess the facility’s adherence to international standards of best practice. During this mission, a team of international experts reviewed the factors affecting the management of safety and the performance of personnel with a focus to identify gaps between plant operations and the requirements outlined in the IAEA Safety Standards.
At the request of EDF Energy, Corporate Risk Associates Ltd (CRA) provided support to the Torness OSART mission in the area of Severe Accident Management (SAM).
In preparation for the visit, CRA produced an evidence pack that reviewed the IAEA Safety Standards and demonstrated compliance. It is noted that there are disparities in the progression of a severe accident due to the differences in plant design between the Advanced Gas-cooled Reactor (AGR) operated at Torness and the Pressurised Water Reactors (PWRs) that the inspectors are more accustomed to. CRA consultants were able to use their experience working with PWRs to compare and relate the IAEA criteria to an AGR.
The review covered topics including the organisation function and its responsibilities, the SAM programme and its analytical support, the development and verification of the procedures and guidelines, the plant emergency arrangements with respect to SAM, the control of plant configuration, and the use of Probabilistic Safety Analysis, periodic safety reviews and operating experience in SAM. Additionally, CRA personnel provided support at EDF Energy’s central office in Barnwood, Gloucestershire and at Torness station during the successful mission; receiving recognition and thanks for the work performed.
