By letter to the U.S. Nuclear Regulatory Commission (NRC) dated March 8, 2004, pursuant to Title 10 of the Code of Federal Regulations, Section 50.55a(a)(3)(i), you requested the use of an alternative to the American Society of Mechanical Engineers Boiler and Pressure Vessel Code,Section XI, Article IWF-5000, Subarticle IWF-5300, of the 1998 Edition through 2000 Addenda, for McGuire Nuclear Station, Unit 2. The NRC staff has reviewed your submittal and has determined that additional information is required. Our questions are provided in the enclosure.

NAME JShea DTerao SCoffin DATE 7/29/04 7/30/04 7/30/04 REQUEST FOR ADDITIONAL INFORMATION RELIEF REQUEST 03-002 SNUBBER EXAMINATIONS DUKE ENERGY CORPORATION MCGUIRE NUCLEAR STATION, UNIT 2 DOCKET NO. 50-370

1. The March 8, 2004, submittal states that the Selected Licensee Commitment (SLC) lists visual examination requirements that are compatible with the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (Code),Section XI, VT-3 requirements. Please describe the differences and provide the technical basis and justification for why the SLC requirements would be an acceptable alternative to the VT-3 requirements required by the ASME Code.

2. Relief is requested from IWF-5300(c) which requires that integral and nonintegral attachments for snubbers, including lugs, bolting, pins, and clamps, shall be examined in accordance with the requirements of this subsection. Please discuss the examination requirements for integral and nonintegral attachments that are performed per the SLC.

In addition please describe the differences and the technical basis and justification for why the SLC requirements would be an acceptable alternative to IWF-5300(c). Is relief requested from the VT-3 requirements only or from the requirement to examine attachments?

3. 10 CFR 50.55a(b)(3)(v) states, in part, that licensees may use Subsection ISTD, in place of the requirements for snubbers in ASME Code Section XI, IWF-5200(a) and (b) and IWF-5300(a) and (b), by making appropriate changes to their technical specifications or licensee controlled documents. Preservice and inservice examinations must be performed using the VT-3 visual examination method described in IWA-2213.

ISTD incorporates the reduced visual examination frequency table as provided in NRC Generic Letter 90-09. Please discuss why ISTD can not be implemented to perform examination/testing of snubbers.
