Program and Inservice Inspection (ISI) Examination Plans through March 8, 2003.

Letters dated November 22, 2002, and December 6, 2002, submitted the IST Program and ISI Examination Plans for the Fourth 10-Year Intervals, and those letters included requested action dates for the attendant Relief Requests. Conference calls were held between NRC (Darl Hood, et al) and NMC (Doug Neve, et al) on December 4, 2002, and January 13, 2003, to discuss implementation of the IST Program and ISI Examination Plans as well as the previously requested action dates.

As discussed during our January 13, 2003, conference call, we are modifying the 10-Year Intervals for the IST Program and ISI Examination Plans.

The IST Program Plan Third 10-Year Interval will be further extended to May 31, 2003, per the 1986 ASME Code,Section XI, IWA-2430(d). The IST Program Plan Fourth 10 Year Interval will be revised to start on June 1, 2003.

The ISI Examination Plan Third 10-Year Interval will be further extended to May 31, 2003, per the 1986 ASME Code,Section XI, IWA-2430(d). The ISI Examination Plan Fourth 10-Year Interval was revised to start on May 1, 2003, per the 1995 ASME Code with 199,6 Addenda,Section XI, IWA-2430(d)(1), (2) and (4). Additionally, we have revised the Fourth 10-Year Interval ISI Examination Plan, which is attached. The revision (Revision 1) removed reference to code cases included in the Draft Regulatory Guide DG-1 091, "lnservice Inspection Code Case Acceptability, ASME Section XI, Division V."

NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION MONTICELLO 4th INTERVAL EXAMINATION PLAN INTRODUCTION

Background:

The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (BPV) Code (hereafter referred to as ASME Section XI, Section Xl, or the Code), Section Xl Inservice Inspection (ISI) Program is prepared and maintained by the Nuclear Management Company (NMC). The Inservice Testing Program (IST) is maintained separately from this program and is submitted under separate cover. The Repair/Replacement Program and Containment Inspection Program (as allowed by 10CFR55a(g)(6)(ii)(B)(5)) are maintained separately from this program and, although they are not submitted, they are available at the plant site for audit and review.

,4th Ten-Year Interval: The Monticello 4th Ten-Year Inserv-ice Inspection Interval is slightly less than 120 months due to an extension of the 3rd Interval (Letters to the NRC in May 2002 and Jaouary 2003 providing notification of 3rd Interval extension initially through March 8, 2003 (M2002057) and subsequently May 31, 2003 (no number yet assigned)). The 4th Interval will overlap the 3rd Interval as permitted by IWA-2430(d)(1),(2),(3), and (4) The 4th Interval begins May 1, 2003 and ends May 31, 2012. Six refueling and maintenance outages are currently scheduled in this time frame.

Component Selection: With the exception of Class I and 2 piping welds, components within the examination plan were selected and scheduled using criteria in the 1995 Edition of ASME Section Xl with thel 996 Addenda (Inspection Program B) and I OCFR50.55a(g)(6)(ii)(A), except where relief has been requested. Per I 0CFR50.55a(b)(2)(xi), the requirements of IWB-1220 in the 1989 Edition of ASME Section Xl, "Components Exempt from Examination,"

shall be used for Class 1 piping instead of the 1995 Edition of ASME Section Xl with 1996 Addenda. Per 10CFR50.55a(b)(2)(xxi)(B) reused CRD Bolting must meet examination requirements for Table IWB-2500-1, Category B-G-2," Item B7.80 of ASME Section XI 1995 Edition with 1995 Addenda.

Selection of Class 1 and Class 2 piping welds in ASME Categories B-F, B-J, C-F-1 and C-F-2 are based on EPRI Topical Report 112657 Rev. B-A. "Revised Risk Informed Inservice Inspection Evaluation Procedure." The Risk Informed Class 1 and Class 2 application was also conducted in a manner consistent with ASME Code Case N-578 "Risk Informed Requirements for Class 1, 2, and 3 Piping, Method B." The use of the RI-ISI program was approved for use on July 27, 2002. (reference TAC MB3819 and Relief Request #1 for 4th ISI Interval) 1.2-1 Revision 1 1117/2003

  • EXAMINATION PLAN INTRODUCTION (cont'd)

Code Edition Summary: The code editions implemented in the ISI Program can be summarized as follows:

-Class 1 (Quality Group A) 1995 Edition with 1.996 Addenda Risk-Informed Program (Relief #1) 1989 Edition IWB-1220 (10CFR50,55a)

Class 1 CRD Bolting (B7.80) Augmented program GE SIL. No. 483R2, 10CFR50.55a(b)(2)(xxi)(B) dated September 26, 2002 specifies 1995 Edition with 1995 Addenda Class 2 (Quality Group B) 1995 Edition with 1996 Addenda Risk-Informed Program (Relief #1)

Class 3 (Quality Group C) 1995 Edition with 1996 Addenda I

MC (Metal Containment) 1992 Edition with 1992 Addenda, Subsection IWE Appendix VIII - Mandatory 1995 Edition with 1996 Addenda as modified by 10CFR50.55a(g)(6)(ii)(C) dated September 26, 2002 Back-ground for PlanlSchedule Development: The examination plan and schedule was developed from ASME Code requirements, Risk-Informed Methodology, individual component examination history and plant scheduling needs such as optimizing insulation removal and scaffolding needs. During the 2nd Interval, a substantial number of component replacements and alterations were made (e.g. the recirculation piping replacement). The intent of the 4th Interval scheduling was to be consistent with the 2nd and 3rd Interval, subject to allowing meaningful accumulation of service time for new components. For Class 1 (category B-F and B-J) and Class 2 Category C-F-1 and C-F-2) Piping Welds examined per the RI-ISI Plan, there may be little schedule correlation with previous ISI Intervals.

1.2-2 Revision 1 1/17/2003

NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION MONTICELLO 4th INTERVAL EXAMINATION PLAN INTRODUCTION (cont'd)

Examination Personnel I Procedures: Inservice Inspection -examination procedures and personnel certifications meet the requirements specified in the 1995 Edition of ASME Section XI with the 1996 Addenda. Additionally, UT personnel and procedures meet the requirements of Mandatory Appendix VIII as modified by 10CFR50.55a dated September 26, 2002, except where relief has been granted.

Reporting of Associated Section XI Programs: The Section XI Repair and Replacement Program, System Pressure Tests and Snubber Functional Tests are administered under separate program documents. Although these programs are administered separately, the activities required by the Repair and Replacement Program, System Pressure Tests and Snubber Functional Tests are reported in the "Inservice Inspection Summary Report" following each refueling outage.

ISI Plan Overall

Description:

The ASME Section XI Inservice Inspection Program is comprised of six parts: Introduction, Source Documents, Requests for Relief, ISI Boundary Drawings, ISI Isometric Drawings, and a table containing the Inservice Inspection Examination Plan and Schedule. The ISI Boundary Drawings outline Quality Group Classifications, (A, B and C). The ISI Isometric Drawings delineate ASME Section Xl components or items that are included in the examination program.

The Inservice Inspection Examination Plan and Schedule lists the ASME Section X1 components by Isometric Drawing Number, System, Code Category, Code Item, Component Description and Required Examination. The Examination Plan and Schedule identify the ASME Section XI Item Number listed in Tables IWB-2500-1, IWC-2500-1, IWD-2500-1 and Subsection IWF, and item number for Risk Informed Tables as identified in EPRI TR-1 12657, thus identifying the examination method. The examination schedule lists the anticipated period and outage for the examination of a given component. The examination schedule is intended to be flexible to allow for deviations in outage length and outage work scope. Therefore, the schedule may be changed, as allowed by the Code, without further notification. Examination distribution was developed in accordance with IWA-2432, Inspection Program B.

1.2-3 Revision 1 1/17/2003

NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION MONTICELLO 4th INTERVAL EXAMINATION PLAN INTRODUCTION (cont'd)

The examination plan and'schedule also contains certain'non-code items to be examined, or examinations beyond Section XI Code requirements. These augmented items include licensee-initiated examinations on NC-7879-6/Tank and NC-ISI-37/W-1, W-2, W-3, W-4, W-12, W-12A shown in the plan and schedule. These items will be examined to the extent practical in accordance with the Section XI Code, 1995 Edition with 1996 Addenda, not the RI-ISI Program. Relief requests will not be submitted for these non-code exams if Section XI Code requirements cannot be met. Non-code exams are also subject to change without prior notification to the NRC.

The Monticello Plant was built prior to the implementation of Section XI Access Requirements. As a result, some components that require examination may not be completely accessible. Welds selected for examination under the Risk Informed Program were selected base on risk ranking, radiation area, and weld accessibility as allowed by EPRI TR-112,657.
