Abstract [en]

Human reliability analysis (HRA) constitutes a central role in the probabilistic safety assessment (PSA) for the low power and shutdown period of a nuclear power plant. This is because a large number of operative and maintenance activities take place during a refuelling outage when the plant, to a great extent, is disassembled, maintained, and then reassembled back to operational mode. The paper presents the HRA approach used in the shutdown PSA for Forsmark 1/2 and 3 nuclear power units in Sweden. Challenges of the analysis comprises handling the large scope of activities to be analysed, development and use of a quantification method consistent with the full power PSA, and integration of HRA with the “technical” part of PSA. Experiences from the analysis and results will also be discussed.
