This program conforms to the requirements of 10CFR50.55a (g), PVNGS Technical Specifications, Technical Requirements Manual, and the PVNGS UFSAR.

Exceptions that are known as of this document preparation date are included in the Requests for Relief Section 8.0.

1.2 The revision is being prepared to update the ISI Program for the 3 rd 10 Year Interval. This includes the utilization of the 2001 Edition including the 2003 Addenda of ASME Section

XI with the exceptions noted below: 1.2.1 Requests for relief from ASME Section XI requirements are included in Section 8.0. These Relief Requests are prepared in a format similar to that documented in the NEI White Paper Revision 1 dated June 2004, entitled: "Standard Format for Requests from Commercial Reactor Licensees Pursuant to 10CFR50.55a". 1.2.2 The 2007 Edition thru the 2008 Addenda was utilized for B-L-1, B-M-1, and C-G for pump and valve body welds requirements. (Ref. Letter 102-06454 and SER dated 09-18-2012). (ACT 4343138) 1.2.3 For clarification, this Interval 3 program was prepared, as was Interval 1 and 2 programs, utilizing 40 month periods. 1.2.4 To support future ISI Programs, reference to the reactor vessel internals aging management program was added (Reference 3.12.3). (CRAI 4353644) 1.3 This revision does not utilize risk informed inservice inspection methodology at this time.

1.4 The information presented is in a form consistent with the 1 st and 2 nd 10 Year Interval ISI Program, the applicable requirements of Standard Review Plan manual and procedures and the recommendations contained in NRC letter dated July 17, 1981, from Mr. R.L. Tedesco, NRC, to E. E. Van Brunt, Jr., APS, "Guidance for Preparing Preservice and Inservice Inspection Programs and Relief Requests - Palo Verde Nuclear Generating Station Units 1, 2 and 3."

2.0 CODE APPLICABILITY 2.1 Based on paragraph 10 CFR 50.55a(b) (2) that was published 12 months prior to the start of the 3 rd 10 Year Interval (3-18-07), the 2001 Edition including the 2003 Addenda of ASME Section XI was referenced as the Code to utilize for preparation of this program. Several exceptions to this code are documented in 10CFR50.55a; each of these exceptions was utilized during the preparation of this program.

  • The exemptions of IWB-1220 for Class 1 piping must utilize the 1989 Edition.

3INT-ISI-2 Rev. 4 4 of 210

  • When qualifying VT-3 personnel per IWA-2317, the proficiency of the training must be demonstrated by initial qualification examination and subsequent examinations on a 3 year interval.
  • The 1997 Edition must be used for IWA-2240 alternative examination methods, a combination of methods, or newly developed techniques.
  • Items B3.120 and B3.140 (nozzle inner radius examinations) of the 1998 Edition must be utilized. An enhanced visual examination with a resolution sensitivity to detect a 1-mil wire or crack may be performed in place of an ultrasonic examination.
  • Must utilize the 1995 Edition for examination Item B7.80 per 50.55a (b)(2)(xxi)(B).
  • IWA-2220, Ultrasonic examination methods are prohibited for surface examinations.
  • The surface examination requirements for HPSI systems, Items B9.20, B9.21 and B9.22 are not required to be performed.

2.2 If a code required examination was considered to be impractical during the preparation of this document because of plant design, geometry, accessibility or other conditions, a Request for Relief from that requirement was prepared and included in Section 8.0. If a code required examination is identified to be impractical during the course of an inspection and the code required percentages are not met, a request for relief will be prepared and submitted after each inspection period, and the final interval closeout no later than 12 months after expiration of the Interval.

2.3 This ISI Program will implement the ASME Section XI 2001 Edition Appendix VIII (Performance Demonstration for Ultrasonic Examination Systems) in accordance with 10 CFR 50.55a. These examinations will be conducted in accordance with the Performance Demonstration Initiative (PDI). The PDI Code Comparison document (Reference 3.12.2) explains the complex relationship of regulatory requirements, ASME requirements, code editions, and the PDI program. (CRAI 4378832
