SUBJECT:

Letter of Correction to Monticello 4 th Interval ISI Plan, Revision 1, 1117/2003 Revision 1 of the Monticello 4th Interval ISI Plan was distributed on 1/17/2003. During a self-assessment, it was discovered that an editorial error was present on page 1.2-1. This assessment finding was entered into our Corrective Action Program as Condition Report 03004203.

The noted error, located in the first paragraph (Background), referenced a non-existent paragraph of 10CFR50.55a. In addition, the same sentence was also noted as being somewhat confusing in its intent.

The sentence In error reads as follows:

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.

This sentence has been corrected and restructured for clarification to the following:

The Containment Inspection Program, as allowed by 10CFR55a(g)(6)(ii)(B), and the Repair/Replacement Program are maintained separately from this program, and, although they are not submitted, they are available at the plant site for audit and review.

The change is noted on the attached, corrected page with double sidebars in the right hand margin.

Please remove page 1.2-1 from your copy of the Monticello Section Xi ISI Plan, Revision 1 and replace it with the attached, corrected page.

ANAEMEN NUCLAR COPAN 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 Xl, 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 Containment Inspection Program, as allowed by 10CFR55a(g)(6)(ii)(B), and the Repair/Replacement Program 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 Inservice Inspection Interval is slightly less than 120 months due to an extension of the 3rd Interval (Letters to the NRC in May 2002 and January 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 1 and 2 piping welds, components within the examination plan were selected and scheduled using criteria in the 1995 Edition of ASME Section XI with the1996 Addenda (Inspection Program B) and 10CFR50.55a(g)(6)(ii)(A), except where relief has been requested. Per 10CFR50.55a(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 XI 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 Xl 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 I 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)
