The Nuclear Regulatory Commission (NRC) is preparing for hurricane season and plans to be ready for any storms that threaten NRC-regulated nuclear facilities.
In a blog posted May 27, the NRC pointed to data from the National Hurricane Center and said that experts are predicting 12-to-14 named storms with at least a couple of major hurricanes.
“After two years of seeing a below average number of storms, some of those experts are saying this could be an unpredictable and potentially dangerous season,” NRC said.
The annual hurricane season runs until Nov. 30, and the NRC staff routinely tracks each storm from formation until dissipation, constantly evaluating whether it could pose a threat to U.S. nuclear plants and other NRC-licensed facilities.
NRC preparations begin with training for all those staff members who might have to respond during a storm, testing of communications systems, and inspections to confirm that nuclear power plants in hurricane-prone areas have completed their extensive hurricane preparations.
If a storm approaches the mainland, the NRC regional offices provide regular updates to the NRC’s Headquarters Operations Center in Rockville, Md. Depending on the location of the storm, the Region II office in Atlanta, the Region I office outside Philadelphia, or the Region IV office in Arlington, Texas, may be involved. These briefings include information about staffing of the regional Incident Response Centers, assignment of additional staff to supplement the NRC resident inspectors at the potentially affected plants, and actions underway to ensure continuous communications with NRC-licensed facilities along the projected path of the storm.
Before a storm even forms, the NRC’s regional offices make sure that appropriate equipment, including satellite phones, are available and operational.
When a storm does form and its projected path shows possible impact on a coastline, one or more of the regional offices begins continuous hurricane tracking using the resources of the National Oceanic and Atmospheric Administration (NOAA)’s National Hurricane Center, other federal agencies and commercial weather forecasting services.
Within 48 hours of expected hurricane force winds, NRC officials are dispatched to the State Emergency Operations Centers in the affected states. Additional NRC personnel are identified and placed “on-call” to respond if needed for any storm-induced emergency.
About 12 hours before the arrival of hurricane force winds, the agency will begin receiving continuous status updates from all of the NRC-licensed facilities in the hurricane’s path. Communications links will also be established with state emergency response officials and other federal response agencies.
During a storm’s landfall, NRC staff members maintain close contact with the plant staff and with NRC resident inspectors on site. If normal communications are lost, emergency communications systems are used.
Following any hurricane, the NRC inspectors help assess the extent of any damage to the facility and, if necessary, respond to any storm-induced problems. The agency also works closely with the Federal Emergency Management Agency (FEMA) to determine when evacuation routes are passable and offsite emergency response organizations will be sufficiently recovered from the hurricane response to resume normal activities.
