Flood Margin Assessment for Coastal Nuclear Power Plants in the U.S
Following the Fukushima Daiichi nuclear disaster in 2011, the Nuclear Regulatory Commission issued a letter to all U.S. nuclear facilities requiring reassessment of their flood design basis using current regulations. Reassessment of flood design basis provides plant owners and developers with the necessary technical input and documentation of calculation methodologies and results to develop Updated Final Safety Analysis (USAR) for submittal to the Nuclear Regulatory Commission (NRC). To support the reassessment effort, RPS provided modelling services for six nuclear power plants in the U.S. to determine the storm surge, wave, tsunami, and seiche conditions each that could impact each plant.
On March 11, 2011, the tsunami following the Tōhoku earthquake damages emergency generators at the Fukushima Daiichi Nuclear Power Plant leading to several nuclear meltdowns and the release of radioactive material.
On March 12, 2012, the NRC requires all licensed nuclear power plants in the U.S. reevaluate using present day information and guidance.
On May 11, 2012, the NRC issues Flooding Hazard Reevaluation Prioritization List for Reactor sites setting individual deadlines for each site.
