NRC Denies Petition for Rulemaking

The NRC has denied a petition for rulemaking submitted on July 26, 2011 by the Natural Resources Defense Council, Inc. (NRDC). The petition requested that the NRC amend its regulations to require nuclear facilities to confirm seismic and flooding hazards every 10 years to address any new and significant information. The petition proposed that licensees update the design basis for structures, systems and components (SSCs) important to safety if necessary. The NRC is denying the petition because the NRC has concluded that it can address this issue outside of rulemaking. In SECY-15-0137, the NRC concluded that it could use an enhanced process (other than rulemaking) to address new information related to external hazards. Subsequently, in Enclosure 2 of SECY-16-0144, the NRC provided additional details of its plan to enhance existing processes to ensure new information of natural hazards are adequately assessed. This new process will specifically focus on seismic and flooding hazards.
