Southern Nuclear Operating Company; Edwin I. Hatch Nuclear Plant, Units 1 and 2
The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an amendment to Facility Operating License Nos. DPR-57 and NPF-5, issued to Southern Nuclear Operating Company, for operation of the Edwin I. Hatch Nuclear Plant (Hatch), Units 1 and 2, respectively. The proposed amendment would revise technical specification (TS) 3.8.1, ``AC SourcesOperating,'' for Hatch, Units 1 and 2, to provide for a one-time extension of the completion time for the Hatch, Unit 1, emergency diesel generators.
Setpoints for Safety-Related Instrumentation
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG-1363, ``Setpoints for Safety-Related Instrumentation.'' This DG is proposed Revision 4 of Regulatory Guide (RG) 1.105. The proposed revision describes an approach that is acceptable to the staff of the NRC to meet regulatory requirements ensuring that setpoints for safety related instrumentation are established and maintained within the technical specification limits. This proposed guide has been revised to incorporate additional information regarding American National Standards Institute (ANSI)/ International Society of Automation (ISA) Standard 67.04.01-2018, ``Setpoints for Nuclear Safety Related Instrumentation,'' since revision 3 of RG 1.105 was issued.
