Reactor Site Criteria Including Seismic and Earthquake Engineering Criteria for Nuclear Power Plants and Proposed Denial of Petition From Free Environment, Inc. et al.

Riepilogo

The Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to update the criteria used in decisions regarding power reactor siting, including geologic, seismic, and earthquake engineering considerations for future nuclear power plants. The proposed rule would allow NRC to benefit from experience gained in the application of the procedures and methods set forth in the current regulation and to incorporate the rapid advancements in the earth sciences and earthquake engineering. In addition, this proposed rule benefits from the public comments received on the first proposed revision of the regulations. This proposed rule primarily consists of two separate changes, namely, the source term and dose considerations, and the seismic and earthquake engineering considerations of reactor siting. The Commission is also proposing to deny the remaining issue in petition (PRM-50-20) filed by Free Environment, Inc. et al.
