1.0Applicable Codes and Standards for Inservice Inspection "In accordance with the requirements of Paragraph 50.55a(g) of 10CFR Part 50, the inservice inspection of Unit l's Steam Generators of the McGuire Nuclear Station will be performed in accordance with the ASME Section XI 1998 Edition and the 2000 Addenda, hereafter referred to asSection XI. The inservice inspection examinations will be performed in accordance with Inspection Program B of Section Xl. All examinations will be performed to the extent practicable within the limitations of design, geometry and materials of construction of the component."

Note: Per Relief Request 10-MN-01, the NRC granted McGuire approval of a proposed alternative to the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code (the Code) requirements for ISI. The alternative delays the required update of the McGuire 1 Code of Record for the fourth ISI interval until July 15, 2014. Therefore ASME Section XI 1998 Edition and the 2000 Addenda will be the McGuire 1 Code of Record until Julyl4th, 2014.

Note: The steam generators are not included in the McGuire Nuclear Station's 4th interval Inservice Inspection (ISI) plan. As a result, this stand-alone SG ISI plan has been developed for the Fourth Interval which covers 12/1/2011 thru 11/30/2021.

1.1 Additional Codes and Standards Used Steam Generator tubing will be inspected as required by ASME Section XI and the Technical Specifications for McGuire Nuclear Station. The Steam Generator Maintenance and Engineering (SGME) group of the Corporate Programs and Components Engineering division has overall responsibility for this inspection.

1.2 Code Case Applicable to ASME Boiler & Pressure Vessel Code Section XI The following code cases will be used for the Fourth Interval Inservice Inspection Program at McGuire Unit 1 for the Steam Generator Tubing inspections:

None Note: Reference Relief Request 10-MN-01 for all applicable conditions.

1.3 Applicable Duke Power Administrative Procedures The following Duke Energy Company procedures will be used to control steam generator tubing inservice inspection activities and inservice inspection plans and reports:

The volumetric method of inspection will be used to inspect the steam generator tubing as required. Each inspection will be performed under the QA Program of the organization performing the inspection.

NSD 703 will be used to review, approve, and control all vendor procedures that are used to perform the steam generator tubing inservice inspection.

3.1 Volumetric Inspection Steam generator tubing will be examined using a volumetric inspection method to meet the requirements of Section XI and the McGuire Technical Specifications. The Steam Generator Maintenance and Engineering group of the Corporate Programs and Component Engineering division has overall responsibility for implementing and reporting inspections pertaining to steam generator tubing.
