Did NRC conduct these studies at each nuclear power plant site or did NRC do a generic analysis of representative nuclear power plants?
Response: The NRC initially conducted detailed engineering studies on a number of representative plants that looked at damage that could be caused to plants by large commercial aircraft. These studies found that there were enough differences between the plants that site-specific studies would be worthwhile. The NRC Phase 1, 2, and 3 assessments are site-specific. They look at how potential damage to each plant might affect the reactor’s core, containment, and spent fuel pool and identify mitigating strategies for losses of large areas of the plant.
