Nuclear Regulatory Commission February 24, 2015 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) has granted the request of PPL Susquehanna, LLC to withdraw its application dated September 18, 2012, as supplemented by letter dated May 10, 2013, for a proposed amendment to Renewed Facility Operating License Nos. NPF-14 and NPF-22 for the Susquehanna Steam Electric Station, Units 1 and 2. The proposed amendment would have changed Technical Specification (TS) Surveillance Requirements 3.8.1.9, 3.8.1.11, 3.8.1.12, and 3.8.1.19 in TS 3.8.1, ``AC SourcesOperating.'' Specifically, the proposed amendments would increase the diesel generator (DG) acceptable minimum steady state voltage when operating in emergency/isochronous mode.

The U.S. Nuclear Regulatory Commission (NRC) is soliciting public comment on its draft Interim Staff Guidance (ISG) for Natural Phenomena Hazards (NPH) in Fuel Cycle Facilities. Fuel cycle facility licensees are required to conduct and maintain an Integrated Safety Analysis (ISA). This analysis must examine potential accident sequences caused by process deviations or other events internal to the facility and credible external events, including natural phenomena. During inspections of selected fuel cycle facilities to confirm that the facilities were in compliance with regulatory requirements to address natural phenomena hazards, the NRC staff identified several unresolved items (URIs). The ISG provides criteria and methods that the staff can use to review the treatment of NPH at fuel cycle facilities as evaluated in the facility ISA.
