⚛️Draft NUREG Guidelines for Inservice Testing at Nuclear Plants
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft report entitled NUREG-1482, Revision 4, "Guidelines for Inservice Testing at Nuclear Power Plants: Inservice Testing of Pumps and Valves and Inservice Examination and Testing of Dynamic Restraints (Snubbers) at Nuclear Power Plants." This report provides a basic understanding of the regulatory basis for pump and valve inservice testing (IST) programs and dynamic restraint (snubbers) examination and testing programs at nuclear power plants. It also provides information regarding the NRC's involvement in the development of the American Society of Mechanical Engineers (ASME) "Operation and Maintenance of Nuclear Power Plants," Division 1, "OM Code: Section IST" (OM Code).

The U.S. Nuclear Regulatory Commission (NRC) has published a final site-specific environmental impact statement (EIS), issued as NUREG-1437, Supplement 2, Second Renewal, "Site-Specific Environmental Impact Statement for License Renewal of Nuclear Plants Regarding Subsequent License Renewal for Oconee Nuclear Station, Units 1, 2, and 3, Final Report." This EIS evaluates, on a site-specific basis, the environmental impacts of subsequent renewal of Renewed Facility Operating License Nos. DPR-38, DPR-47, and DPR-55 for an additional 20 years of operation for Oconee Nuclear Station, Units 1, 2, and 3 (Oconee Station), respectively. Oconee Station is located in Seneca, South Carolina, approximately 30 miles west of Greenville. Possible alternatives to the proposed action of subsequent license renewal for Oconee Station include the no-action alternative, a new nuclear alternative, a natural gas combined-cycle alternative, and a combination alternative.

The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 4 to Regulatory Guide (RG) 1.32, "Criteria for Power Systems for Nuclear Power Plants," and new RG 1.238, "Criteria for the Protection of Class 1E Power Systems and Equipment for Nuclear Power Plants." RG 1.32, Revision 4, describes an acceptable approach for use in complying with NRC regulations for the design, operation, and testing of electric power systems in nuclear power plants. RG 1.238 describes an acceptable approach for use in complying with NRC regulations for protection of Class 1E power systems and equipment at nuclear power plants. The NRC is also withdrawing RG 1.41, "Preoperational Testing of Redundant On-Site Electric Power Systems to Verify Proper Load Group Assignments," since its guidance is incorporated into RG 1.32, Revision 4.
