Nuclear Regulatory Commission September 26, 2018 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) has granted the request of NextEra Energy Duane Arnold, LLC (NextEra) to withdraw its application dated December 19, 2017, for a proposed amendment to Duane Arnold Energy Center (DAEC), Facility Operating License No. DPR-49. The proposed change would have added Technical Specifications (TS) 3.2.3, ``Linear Heat Generation Rate (LHGR),'' and modified TS 1.1, ``Definitions,'' TS 3.4.1, ``Recirculation Loops Operating,'' and TS 5.6.5, ``Core Operating Limits Report (COLR)'' to reflect the LHGR change. Modifications associated with TS 3.2.1, ``Average Planar Linear Heat Generation Rate (APLHGR),'' and the new TS 3.2.3 would also have been added to the actions for TS 3.3.4.1, ``End of Cycle Recirculation Pump Trip (EOC-RPT) Instrumentation,'' and TS 3.7.7, ``The Main Turbine Bypass System.'' Subsequently, by letter dated August 21, 2018, NextEra withdrew the amendment request.

The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 4 to Regulatory Guide (RG) 1.160, ``Monitoring the Effectiveness of Maintenance at Nuclear Power Plants.'' Regulatory Guide 1.160, Revision 4, has been revised to address new issues identified since Revision 3 of RG 1.160 was issued. This RG endorses, with clarifications, NUMARC 93-01, ``Industry Guidelines for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants,'' Revision 4F. The proposed revision describes methods that are acceptable to the NRC staff for compliance with the requirements for monitoring the effectiveness of maintenance at nuclear power plants.
