Watching Response Centers Put Trucks on the Road

The nuclear industry has officially opened two National Response Centers — in Memphis, Tenn., and Phoenix, Ariz. These response centers help U.S. nuclear power plants meet the requirements of the NRC’s Mitigation Strategies Order, which we issued after the Fukushima accident.

The centers, previously called Regional Response Centers, contain extra equipment to duplicate plants’ emergency diesel generators, pumps, hoses and so on. This equipment would maintain plant safety functions for an indefinite period if an event disabled a plant’s installed safety systems. An industry group, called the Strategic Alliance for FLEX Emergency Response (SAFER), is managing the response centers. This organization also has two control centers that are separate from response centers and would coordinate equipment deliveries.

NRC staff observed these “proof-of-concept” exercises. The first demonstrated transporting emergency equipment by road from the Memphis response center to the Three Mile Island Nuclear Station in Pennsylvania within the required time. The second exercise involved sending equipment by air from the Phoenix response center to the Surry Power Station in Virginia within the required time.

The NRC staff watched to make sure the equipment can be successfully shipped and delivered. We also observed and evaluated the plants’ — and SAFER’s– communication and coordination throughout the exercises. The conclusions we’re drawing from these exercises will be one input in deciding whether the plants can meet the requirements of Phase 3 of the Mitigation Strategies Order. We’ll send the industry a letter reviewing the performance of the national response centers and SAFER this fall.

While the NRC regulates the individual nuclear power plants that would request and receive the equipment, SAFER is not an NRC licensee. Nevertheless the NRC’s regulatory role does extend to the National Response Centers. Since the centers are key to how plants meet the Mitigation Strategies Order, we’re certainly interested in their performance. To expedite the availability of these Centers to respond, the NRC is working in parallel to design our regulatory oversight approach. Whatever the exact mechanism, you can be sure that the key consideration will be protecting the public’s health and safety.
