NRC proposes plane crash design certification

26 April 2007

A proposal from the US Nuclear Regulatory Commission (NRC) would require each applicant for a new reactor design to assess how the design, to the extent practicable, can have greater built-in protections to avoid or mitigate the effects of a large commercial aircraft impact, making them even more resistant to an attack.

The move is the third in a series of major steps to enhance the post-11 September security of nuclear power plants.

The NRC will seek comment from the public, the nuclear industry and the technical community on the proposal later this year.

In 1985 the NRC said it expected reactor designers to build in more safety features to cope with beyond design basis severe accidents as reactor designs advanced. However, it did not require specific features, leaving that to plant designers.

However, the proposed rule will affect new applicants for reactor design certification and applicants for a combined license that does not reference a certified design.
