Preoperational Testing of Instrument and Control Air Systems

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-1268, ``Preoperational Testing of Instrument and Control Air Systems.'' This regulatory guide is being revised to address new issues that have been raised since RG 1.68.3 was first issued. These include vibration testing of instrument and control air systems (ICAS) to meet seismic requirement, ICAS air-dryer testing to meet dew point design requirements, ICAS accumulator check valves and solenoid valves operating and testing experience, an update to ISA S7.3 for acceptable industry standards for oil, water and particle matter in ICAS.

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.

2. 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, ``Preoperational Testing of Instrument and Control Air Systems,'' is temporarily identified by its task number, DG-1268. The DG-1268 is proposed revision 2 of Regulatory Guide 1.68.3, dated January 1977.

   This guide describes methods and procedures the staff of the NRC considers acceptable to implement preoperational testing of the instrument and control air systems (ICAS) in a commercial nuclear power plant. Successful demonstration of the operability of the ICAS is one of the items required by Appendix A, ``General Design Criteria for Nuclear Power Plants,'' of Title 10 of the Code of Federal Regulations, part 50, ``Domestic Licensing of Production and Utilization Facilities'' (10 CFR part 50). This guide also describes the methods that the NRC staff finds acceptable for the initial test program for ICAS systems, structures, and components (SSCs) in accordance with the regulations in 10 CFR Part 52, ``Licenses, Certifications, and Approvals for Nuclear Power Plants,'' Subpart B, ``Standard Design Certifications,'' and Subpart C, ``Combined Licenses.''

   For the Nuclear Regulatory Commission.
