Section 50.55a(a)(3) states in part that alternatives to the requirements of paragraph (g) may be used, when authorized by the NRC, if the applicant demonstrates that: (i) the proposed alternatives would provide an acceptable level of quality and safety, or (ii) compliance with the specified requirements would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety.

Pursuant to 10 CFR 50.55a(g)(4), ASME Code Class 1, 2, and 3 components (including supports) will meet the requirements, except the design and access provisions and the preservice examination requirements, set forth in ASME Code,Section XI, to the extent practical within the limitations of design, geometry, and materials of construction of the components. The regulations require that inservice examination of components and system pressure tests conducted during the first 10-year interval and subsequent intervals comply with the requirements in the latest edition and addenda of Section XI of the ASME Code incorporated by reference in 10 CFR 50.55a(b) twelve months prior to the start of the 120-month interval, subject to the limitations and modifications listed therein. The ISI Code of Record for Catawba 2 for the second 10-year ISI interval is the ASME Code,Section XI, 1989 edition, no addenda.

Enclosure

Section 10 CFR 50.55a(g)(4)(iv), states that the inservice examination of components and system pressure tests may meet the requirements set forth in subsequent editions and addenda that are incorporated by reference in Section 50.55a(b), subject to the limitations and modifications listed therein and NRC approval. Portions of the editions or addendum may be used provided that all related requirements of the respective editions and addenda are met.

3.0 TECHNICAL EVALUATION

3.2. Applicable Code Requirements ASME Code of record for the second 10-year ISI interval is the 1989 edition with no addenda of Section XI.

3.3 Licensees Request Pursuant to 10 CFR 50.55a(g)(4)(iv), the licensee requests approval to use selected portions of the ASME Code,Section XI, 1998 edition with the 1999 and 2000 addenda, in lieu of the 1989 edition, for the remainder of the Catawba 2 second 10-year ISI interval (Class 1, 2, and 3 components and component supports), currently scheduled to end on August 19, 2006.

3.4 Proposed Subsequent Portions of the ASME Code and Related Requirements Catawba 2 proposes using the requirements of certain paragraphs and related portions of the 1998 edition with the 1999 and 2000 addenda of Section XI of the ASME Code.

ASME Code Section XI Portions of 1998 Edition with Related Requirements of subparagraphs for which use the 1999 and 2000 Addenda the 1998 Edition with the of a later Edition/Addenda is to be Used 1999 and 2000 Addenda to Requested be Met IWA-2210 IWA-2210 (Note 1) Section V: Article 9 Section XI: Table IWA-2210-1, IWA-5240 N/A (Note 2) IWA-2216 Section V: Article 9 IWA-2220 IWA-2220 (Note 3) Section V: Articles 6 and 7 Section XI: Appendix IV IWA-2230 IWA-2230 (Note 4) Section V: Articles 2 and 8 Section XI: Appendix I

ASME Code Section XI Portions of 1998 Edition with Related Requirements of subparagraphs for which use the 1999 and 2000 Addenda the 1998 Edition with the of a later Edition/Addenda is to be Used 1999 and 2000 Addenda to Requested be Met IWA-2300 IWA-2300 (Note 5) Section XI: IWA-1600 Appendix VI Appendix VII N/A IWC-1223 No related requirements Table IWC-2500-1 Table IWC-2500-1 See Note 6 Examination Category C-C, Examination Category C-C, Item C3.20 Item C3.20 Notes

1. Included in the scope of this request are IWA-2211, IWA-2212, IWA-2213, and IWA-2215.

2 IWA-2216 of the 1989 edition shall continue to be used, as well as IWA-2216 of the 1998 edition with the 1999 and 2000 addenda.

3. Included in the scope of this request all paragraphs of IWA-2220.
4. Included in the scope of this request are all paragraphs of IWA-2230, except for IWA-2234.
5. Included in the scope of this request are all paragraphs of IWA-2300.
6. The later Code edition and addenda require fewer welded attachments to be examined.

Because the number of completed examinations performed using the 1989 edition have exceeded the number required using the later edition and addenda, no more welded attachments are required to be examined. As such, there are no related requirements to be met.

4.0 EVALUATION The licensees ISI ASME Code of record is the 1989 edition with no addenda. The licensees proposed use of portions of subsequent edition and addenda to the ASME Code,Section XI that is incorporated by reference in 10 CFR 50.55a(b)(2) subject to any modifications and limitations is in accordance with 10 CFR 50.55a(g)(4)(iv). The NRC staffs review has focused on whether the related requirements of the respective code and addenda are being met and any modifications and limitations apply.

Subsubarticle IWA-2210 including paragraphs IWA-2211, IWA-2212, IWA-2213, and IWA-2215 of the 1998 edition with the 1999 addenda provide acceptable requirements for performing visual examinations. The licensee identified the related requirements of the 1998 edition with the 1999 and 2000 addenda that will be met. The NRC staff finds this acceptable.

The proposed later edition and addenda provide guidance for performing remote visual examinations in paragraph IWA-2216. Paragraph IWA-2216 in the 1989 edition addresses cleaning for visual examinations. Therefore, the licensee will use IWA-2216 of the 1989 edition in addition to IWA-2216 of the 1998 edition with the 1999 and 2000 addenda. The NRC staff finds this acceptable.

Subsubarticle IWA-2220 Surface Examination, including paragraphs IWA-2221, IWA-2222, and IWA-2223 of the 1998 Edition with the 1999 addenda provide acceptable requirements for performing surface examinations. The licensee identified the related requirements of the 1998 edition with the 1999 and 2000 addenda that will be met. The NRC staff finds this acceptable.

Subsubarticle IWA-2230, Volumetric Examination, including paragraphs IWA-2232 and IWA-2233 of the 1998 edition with the 1999 addenda provide acceptable requirements for performing volumetric examinations. The licensee identified the related requirements of the 1998 edition with the 1999 and 2000 addenda that will be met. The NRC staff finds this acceptable.

The licensee requests the use of all paragraphs in subarticle IWA-2300, Qualifications of Nondestructive Examination Personnel, of the 1998 edition with the 1999 and 2000 addenda of Section XI. Included in this subarticle are paragraphs IWA-2314(a) and (b). As required by the modifications and limitations in 10 CFR 50.55a(b)(2)(xviii), "Certification of NDE personnel,"

Level I and II nondestructive examination personnel shall be recertified on a 3-year interval in lieu of the 5-year interval specified in IWA-2314(a) and (b) of the 1998 edition with the 1999 and 2000 addenda. The modification and limitations in 10 CFR 50.55a(b)(2)(xviii) must be followed.

The use of the other paragraphs in Subarticle IWA-2300 are acceptable.

IWC-1223, "Inaccessible Welds," of the 1998 edition with the 1999 addenda defines inaccessible welds that are exempt from examination. The NRC staff finds the use of the definition in IWC-1223 acceptable.

Table IWC-2500-1, Examination Category, C-C, Item C3.20, Welded Attachments of Piping.

The 1989 edition of the ASME Code,Section XI required the examination of integrally welded attachments in piping of those components required to be examined under Examination Categories C-F and C-G. The 1998 edition with the 1999 addenda requires that selected samples of welded attachments be examined each inspection interval. The 1998 edition with the 1999 addenda requires fewer integrally welded attachments for piping to be inspected. The NRC staff has approved the use of this later addition with no modification or limitations. The NRC staff finds the use of the subject portion of the later edition and addenda acceptable.

5.0 CONCLUSION

Based on the NRC staffs review and comparison of the ASME Section XI Codes, the NRC staff finds that the identified portions of the 1998 edition with the 1999 and 2000 addenda will provide an acceptable level of quality and safety in lieu of the requirements in the 1989 edition, with one exception. The modification and limitation of 10 CFR 50.55a(b)(2)(xviii) must be followed in lieu of paragraphs IWA-2314(a) and (b). As required by the modifications and limitations in 10 CFR 50.55a(b)(2)(xviii), "Certification of NDE personnel," Level I and II nondestructive examination personnel shall be recertified on a 3-year interval in lieu of the 5-year interval specified in IWA-2314(a) and (b) of the 1998 edition with the 1999 and 2000 addenda. The NRC staff authorizes the alternative with this noted exception for the remainder of the second 10-year ISI interval at Catawba Unit 2.
