Every year, IRSN takes part in the Regulatory Information Conference (RIC) organized by the United States Nuclear Regulatory Commission (US NRC) in Washington DC. The two partners have begun talks on the subject of flood hazards and Probabilistic Flood Hazard Assessment (PFHA).
At the 2014 edition of the Regulatory Information Conference (RIC), held from March 11 to 13, the director general of IRSN presented two topics: research conducted in an international framework, and how TSOs support the safety authorities. Building on technical information exchanges within an IAEA framework, the conference provided the opportunity for IRSN flood hazard specialists and their NRC counterparts to identify a community of interest in examining recently developed methods, especially based on the probabilistic approach.
Since the Fukushima Daiichi power plant accident, which made it apparent that extreme natural phenomena need to be taken into account worldwide, the NRC has looked to international experience for new impetus in updating its deterministic approach to flood hazard assessment, which largely dates back to the 1970s.
In this respect, the work carried out by IRSN after the flooding of the Blayais power plant on December 27, 1999 – which led to major changes in how this hazard is taken into account in France – could be a source of cooperation between the two partners.
