What were some of the long-term actions taken by the NRC?
In the months following the terrorist attacks of September 11, 2001, the NRC issued Orders to nuclear power reactors, decommissioning reactors, gaseous diffusion plants, the uranium conversion facility, fuel fabrication facilities, and panoramic irradiator license requiring them to implement enhanced security measures designed to protect against an increased threat. Additional information on this subject can be found in the testimony provided by former Chairman Meserve to the U.S. Senate on June 5, 2002. The NRC also initiated a number of studies on the effects of a large commercial aircraft hitting a nuclear power plant. Those studies are ongoing.
