Nuclear Regulatory Commission March 12, 2015 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an amendment to Renewed Facility Operating License No. DPR- 35, issued to Entergy Nuclear Operations, Inc., for operation of the Pilgrim Nuclear Power Station. The proposed amendment would modify the Safety Limit Minimum Critical Power Ratio from >= 1.08 to >= 1.10 for two recirculation loop operation and from >= 1.11 to >= 1.12 for single loop operation.

The U.S. Nuclear Regulatory Commission (NRC) is informing the public of its intent to prepare a supplement to the U.S. Department of Energy's (DOE's) ``Final Environmental Impact Statement for a Geologic Repository for the Disposal of Spent Nuclear Fuel and High-Level Radioactive Waste at Yucca Mountain, Nye County, Nevada'' (February 2002), and its ``Final Supplemental Environmental Impact Statement for a Geologic Repository for the Disposal of Spent Nuclear Fuel and High- Level Radioactive Waste at Yucca Mountain, Nye County, Nevada'' (July 2008). The NRC staff determined in September 2008 that it is practicable to adopt, with further supplementation, the DOE's environmental impact statements (EISs). The NRC staff concluded that the EISs did not address adequately all of the repository-related impacts on groundwater or from surface discharges of groundwater.
