          - [NRC-2012-0064]

# AGENCY:

Nuclear Regulatory Commission.

# ACTION:

Draft regulatory guide; request for comment.

# SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC or the Commission) is issuing for public comment draft regulatory guide (DG), DG-1265, “Initial Test Program of Condensate and Feedwater Systems for Light-Water Reactors.” DG-1265 is proposed revision 2 of Regulatory Guide 1.68.1, “Preoperational and Initial Startup Testing of Feedwater and Condensate Systems for Boiling Water Reactor Power Plants,” dated January 1977.

                        This regulatory guide is being revised to: (1) expand the scope of the guide to encompass preoperational, initial plant startup, and power ascension tests for the condensate and feedwater systems in all types of light water reactor facilities licensed under Title 10 of the                         *Code of Federal Regulations*                         (10 CFR) Parts 50 and 52; and (2) to incorporate lessons learned by the NRC staff since the last revision.                    

# DATES:

Submit comments by May 18, 2012. Comments received after this date will be considered if it is practical to do so, but the NRC is able to ensure consideration only for comments received on or before this date. Although a time limit is given, comments and suggestions in connection with items for inclusion in guides currently being developed or improvements in all published guides are encouraged at any time.

## II. Further Information

The NRC is issuing for public comment a draft guide in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public such information as methods that are acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.

The draft regulatory guide, entitled, “Initial Test Program of Condensate and Feedwater Systems for Light-Water Reactors” is temporarily identified by its task number, DG-1265. The DG-1265 is proposed revision 2 of Regulatory Guide 1.68.1, dated January 1977.

                    This guide describes the methods that the staff of the NRC considers acceptable to implement Appendix A, “General Design Criteria for Nuclear Power Plants,” to Title 10, of the                     *Code of Federal Regulations*                     (CFR), Part 50, “Domestic Licensing of Production and Utilization Facilities” (10 CFR Part 50), including, but not limited to, Criterion 4, “Environmental and Dynamic Effects Design Basis,” Criterion 11, “Reactor Inherent Protection,” Criterion 14, “Reactor Coolant Pressure Boundary,” and Criterion 15, “Reactor Coolant System Design” regarding the initial test program (ITP) for condensate and feedwater (FW) systems, including condensate storage and supply, for light-water reactors (LWRs) and for startup feedwater (SFW), auxiliary feedwater (AFW) or emergency feedwater (EFW) systems for pressurized-water reactors (PWRs). This guide also describes methods that the NRC staff finds acceptable for testing condensate, FW, SFW/AFW/EFW (PWR only) structures, systems, and components (SSCs) in accordance with Subpart B, “Standard Design Certifications,” and Subpart C, “Combined Licenses,” of 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants.”
