Inservice Inspection Program ASME Section XI Required Examinations Fourth 10- Year Interval Request for relief Regarding Request No. 35 R.ED Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Vissing:
The purpose of this letter is to seek approval for the use of Relief Request number 35 concerning the use of ASME Section XI Code, 1995 Edition, 1996 Addenda. This code will be used to develop our Fourth 10-Year Interval ISX Program on Class 1, 2, and 3 components, with the exception of Containment requirements of XWE and XWL.
This relief is requested pursuant to the provisions of 10 CFR 50.55a (a) (3) (i), the use of a later ASME Section XI Code. Justification is included in the enclosed relief request.
Also included as Attachment (I) is our evaluation, analysis, and classification of differences between the 1989 Code and the 1995 Code with 1996 Addenda. We have concluded from this evaluation that our proposed use of the 1995/1996 Code provides an acceptable level of quality and safety.
Since this relief request is being used as the basis for the development of our Fourth Interval ISI program, approval is needed by December 31, 1999.

E<nclosure 1 Rochester Gas and Electric Corporation Ginna Station Docket No. 50/244 Fourth 10- Year Interval Request for Relief No. 35 ASME Code Section XI Alternative for the Fourth Interval ISI Program System/Component(s) for which Relief is Requested:
This Relief Request is requested for Inservice Inspection of all ASME Class 1, Class 2, and Class 3 components in accordance with the rules provided in ASME Section XI Code, Division 1.
II. Code Requirement:
10 CFR 50.55a specifies that the ASME Section XI Code, 1989 Edition, should be utilize for the preparation and use of licensees Inservice Inspection Program as well as their Repair and Replacement Program. Later editions of ASME Section if XI Codes may be utilized only approved by the NRC.
III. Code Requirement from Which Relief is Requested:
R.E. Ginna Nuclear Power Plant is requesting relief from utilizing the ASME Section XI Code, 1989 Edition, and is requesting permission to use the ASME Section XI Code, 1995 Edition with the 1996 Addenda for Class 1, 2, and 3 components for our Fourth Interval ISI Program in its place.
This Relief Request does not address Containment (IWE/IWLand applicable IWA) requirements. The Containment requirements shall be performed to ASME Section XI Code, 1992 Edition with the 1992 Addenda. This year and edition of ASME Section XI Code is the basis for the EPRI/ Industry Guideline which will be used to develop and implement our Containment Inspection Program.
Request for Relief No. 35 Page 1 of 3
IV. Basis for Relief:
Relief is requested pursuant to the provisions of 10 CFR 50.55a(a)(3)(i), request for approval to use a later ASME Section XI Code. The proposed alternative will provide an acceptable level of quality and safety.
On December 3, 1997, the NRC issued a proposed change in the Federal Register to amend 10 CFR 50.55a for Inservice Inspection. The proposed rulemaking endorsed the use of ASME Section XI Code, 1995 Edition with the 1996 Addenda for the Inservice Inspection as well as Repair or Replacement of Class 1, 2, and 3 components. This later code provides clarification to those requirements specified within the currently approved Code (1989 Section XI). By utilizing the later Section XI Code for Inservice Inspection as well as Repair and Replacement of Class 1, 2, and 3 components, the number of needed relief requests that the NRC would be required to process would be minimized.
It is requested that ASME Section XI Code, 1995 Edition with the 1996 Addenda be utilized to develop R.E. Ginna Nuclear Power Plant Fourth Interval Program.
V. Alternate Examinations:
R.E. Ginna Nuclear Power Plant requests that our Fourth Interval Inservice Inspection (ISI) Program as well as our Repair and Replacement Program shall conform to ASME Section XI Code, 1995 Edition with the 1996 Addenda for Class 1, 2, and 3 components including supports.

~h VI. Justification for the Granting of Relief:
On December 3, 1997, the NRC issued a proposed change in the Federal Register to amend 10 CFR 50.55a for Inservice Inspection. The proposed Rulemaking endorsed the use of ASME Section XI Code, 1995 Edition with the 1996 Addenda for the Inservice Inspection as well as for Repair or Replacement of Class 1, 2, and 3 components.
The use of the Code (1995 with the 1996 Addenda) provides clarification to those requirements specified within the current approved Code (1989 Section XI Code).
NRC approval to utilize the later Section XI Code for Inservice Inspection, as well as Repair and Replacement of Class 1, 2, and 3 components, would minimize the number of needed relief requests that the NRC would be required to process.
VII. Implementation Schedule:
Examinations will be performed during the Fourth 10-year Interval, starting January 1, 2000.

ROCHESTER GAS 4 ELECTRIC CORPORATION R. K. GINNA NUCLEAR POWER PLANT ANALYSIS OF ASMK CODE, SECTION XI, 19S9 TO 1996 ADDENDA May 10, 1999 9909010024
RELIEF REQUEST ¹ 35 ATTACHMENT(1)
For purposes of Inservice Inspection, Rochester Gas and Electric Corporation. (RG&E) proposes to adopt the 1995 Edition with the 1996 Addenda of American Society of Mechanical Engineers (ASME)Section XI Code, except for Subsections IWE and IWL. For IWE and IWL, RG&E will use the 1992Edition with the 1992 Addenda of ASME Section XI. ASME Section IIICode, 1989 Edition shall be used for Repairs and Replacements, as applicable.
Rochester Gas & Electric Corporation has carefully reviewed all of the changes to the ASME Section XI Code from the 1989 Edition through the 1996 Addenda to determine the impact of each revision.
To properly understand these changes, it was necessary to review the Minutes of the ASME Boiler and Pressure Vessel Committee and review each modified paragraph in the context of the change.
When ASME modifies requirements, the specific modification often includes several related paragraphs. Also, it sometimes happens that two completely independent changes will modify the same paragraph. Therefore, it is not always possible to describe any change as merely a modification to a paragraph. Because of this, the evaluation of Section XI changes (Attachment 1, Table 1) is grouped by each action that was passed by the ASME Committee. The ASME descriptions of each action in the Minutes were helpful in determining which actions were editorial and which were clarification of the then current rules.
The attached evaluation lists the following five classifications of changes:
Errata: Basically this is correction of an ASME publication error. These changes do not affect requirements, because they are retroactive to the time the error was introduced.
Editorial: These changes have no technical impact and are so simple that the ASME Main Committee and Subcommittee agree that they do not even warrant discussion at the Committee meetings.
No Significant Change: These revisions consist of clarifications or editorial changes that are discussed and voted on at the Main Committee meeting.
Less Restrictive: These changes reduce the technical requirements of the Code.
Documentation or procedural changes are not listed, as they have no technical impact.
Justification is given for each of these changes.
More Restrictive: These changes increase technical requirements and therefore need no justification for acceptance.
RELIEF REQUEST 0 35 ATTACHMENT(1) assigned by the ASME Code Committee. Therefore, ~
Because these categorizations may seem to be subjective, it was decided to use the categories as change made to Section XI from 1989 to 1996 was reviewed and analyzed using the minutes from each of the ASME Main Committee meetings. (These minutes are available to the public.)
The evaluation describes why the reductions in requirements do not decrease safety. This evaluation is made by reviewing the change in requirements, using the Code Committee minutes, and considering all of the related Code requirements that must also be met.
Because Subsections IWE and IWL stand on their own merit and will not be updated to the 1996 Addenda, no evaluations have been made on the impact of changes. We have determined that other subsections are not afFected by the decision not to update these two subsections.
The evaluation shown in Table I was made to assess whether or not any of the changes made to Section XI, during the period from 1989 to 1996, reduced requirements in a way that would have a negative impact on safety.
On December 3, 1998, the Nuclear Regulatory Commission (NRC) issued a proposed rule incorporating the 1996 Addenda to Section XI into 10CFR50.55a. Five limitations to the use of the 1996 Addenda were proposed. The following addresses the acceptability of these five provisions for RG&E's next ISI interval.
- 1. Engineering Judgment The 1992 Addenda revision to the Foreword did not reduce or change any existing Code requirements. Rather, the change to the Foreword documented ASME's long-standing policy.
These provisions were previously endorsed by the NRC with their acceptance of the Introduction to Section XI from 1970 to 1974.
- 2. Quality Assurance The 1990 Addenda update to NQA-1-1989 made no substantial change in QA requirements.
Rochester Gas & Electric Corporation will apply its Appendix B QA Program to Section XI activities as required by the NRC.
- 3. Class 1 Piping The 1994 Addenda revision incorporating Cases N-198-1, N-322, and N-334 merely exempted from examination inaccessible welds that cannot be examined. Because these welds are inaccessible, the use of the revision reduces the number of relief requests being sent to the NRC.
It has no impact on the number of examinations being performed.
RELIEF REQUEST 8 35 ATTACHMENT(1)
- 4. Class 2 Piping This revision does not incorporate the provisions to which the proposed rulemaking purports to take exception. The provisions about which the proposed rulemaking expresses concern were added to IWC-1220, Table IWC-2500-1, Category C-F, and Figure IWC-2500-7, in the Winter 1983 Addenda (W83), which was adopted by the NRC on May 5, 1988, and has been used at almost every nuclear power plant in the U.S., without exception or limitation.
- 5. Reconciliation of Quality Requirements The NRC's concerns about the 1995 Addenda revision to IWA-4000 are based on the assumption that the revision permits an exception to 10 CFR Part 50, Appendix B, QA requirements. While RGB'elieves this conclusion to be inaccurate, RGB will implement all applicable requirements of Appendix B and will not use Section XI to take exception to Appendix B requirements.
The evaluation summarized in Table 1 shows that even though some changes to Section XI from 1989 to 1996 are classified as "less restrictive," the reductions in requirements have no impact on safety. This is the conclusion of the ASME Boiler and Pressure Vessel Committee, and our conclusion based on our extensive evaluation of every change made to Section XI from 1989 to the 1996 Edition.
