On 28-30 April 2014, the CSNI Working Group on Risk Assessment (WGRISK) held a workshop on Fire Probabilistic Risk Assessment (PRA) in Garching, Germany. The meeting was attended by nearly 60 participants from 15 countries, the NEA and the International Atomic Agency (IAEA).
The workshop objectives were to support assessment of the current state of probabilistic analyses of fire hazards for nuclear installations at the design stage and during all plant operational states from start of operation up to the longer lasting post-commercial operating phases; to support re-evaluation of Fire PRA, in particular as a tool to address the lessons learned from the post-Fukushima investigations and stress tests with respect to fire events; to share methods as well as good practices and experiences among member states on probabilistic risk assessment of fire hazards and event combinations with fires; and to identify new potential topics for further WGRISK activities in this area, including potential update of the state-of-the-art report (SOAR) on fire risk analysis.
