Abstract
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.
