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 (7-17-08), 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.

4 of 209 3INT-ISI-1 Rev 3

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

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.

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.

 BOUNDARIES 3.2.1       A complete set of P&ID drawings indicating the Inservice Inspection boundary are maintained at the PVNGS site. These drawings illustrate the ASME Class 1, 2, and 3 systems; components; and boundaries scheduled for examinations and pressure testing. A referenced listing of these drawings is documented in Section 9.0. 3.2.2       A set of ISI (Zone) Drawings is included in Section 10.0. These drawings are utilized for the planning and scheduling of specific ASME Class 1 and 2 examinations throughout the 10 Year Interval. These also document the location and number of welds, components, and supports. These Zone drawings are controlled in conjunction with this program manual. (CRAI 4398773)
 : 1. Zone drawings have also been added for diesel generator skid piping supports. 3.3     ACCESSIBILITY 3.3.1       The preservice examinations were performed with examination techniques, automated or manual, similar to those planned for use during Inservice Inspections. The examination limitations noted during the preservice examinations were documented in Requests for Relief submitted with the preservice examination program. There has also been a number of additional code limitations noted during the 1 st and 2 nd 10 Year Intervals and Request for Relief submitted. If included in the required 3 rd Interval examinations they will again be evaluated and relief requested. Note Section 8.0 identifies all the reliefs submitted during the preparation and implementation of the 3 rd Interval.
 of 209 3INT-ISI-1 Rev 3 3.3.2       All items that are scheduled for examination will be examined to the extent practical. In addition, any code limitations that are noted during the examinations will be documented. If relief is required from any of these examinations, a Request for Relief will be submitted after the relief is discovered and prior to 12 months after the interval ends. 3.4       EXAMINATION TECHNIQUES 3.4.1       The three types of examinations utilized to perform Inservice Inspections, along with the actual nondestructive examination technique, are identified in the legend below: VT - Visual VT - 1  (General Condition) VT - 2  (Leakage)
