Pursuant to 1 OCFR50.55a(g)(4)(iv), Dominion requests approval to use a portion of later editions and addenda of ASME Section XI, specifically the 2001 Edition through the 2003 Addenda, Subsection IWE, Table IWE-2500-1, Category E-A, ltem number E l.12.
The use of ltem E l.12 is requested to clarify where the VT-3 examination method is intended to be performed (i.e., wetted surfaces of submerged areas) for the IWE containment surfaces requiring examination.
The 2001 Edition through the 2003 Addenda of ASME Section XI Code limits parts (surfaces) to be examined for ltem E l.12 to wetted surfaces of submerged areas. The 1992 Edition with the 1992 Addenda of ASME Section XI requires examination of accessible surface areas similar to ltem number El. 1 1 of the 1992 Edition with the 1992 Addenda ASME Section XI Code. The wetted surfaces of submerged areas was only part of the examination requirement in the 1992 Edition with the 1992 addenda of the ASME Code.
ASME Code Components Affected The North Anna and Surry containments are sub-atmospheric. The metallic liner of the concrete containment is examined under the rules of ASME Section XI, IWE (metallic liners of Class CC components). The components affected are the containment surface areas of the liner as addressed by Table IWE-2500-1, Category E-A, ltem number E l.12.
The 1992 Edition with 1992 Addenda ltem E l.12 - includes all accessible surface areas of the metallic liner including wetted surface areas of submerged areas.
The 2001 Edition through 2003 Addenda ltem E l.12 - includes only the metallic liner wetted surface areas of submerged areas.
Applicable Code Edition and Addenda
The first ten-year Containment lnservice lnspection Plan for IWE for the North Anna and Surry units is based upon the 1992 Edition with the 1992 Addenda of ASME Section XI.
The 1992 Edition with the 1992 Addenda of ASME Section XI, Subsection IWE, Table 2500-1, Category E-A, ltem number E l.12, requires a 100% visual, VT-3 examination of the accessible surface areas. The parts (surfaces) to be examined include the following Page 1 of 5

Serial No.06-856 Docket Nos. 50-2801281 and 50-3381339 of Table IWE-2500-1 using the VT-3 examination method must be conducted once each interval. The "owner-defined" visual examination provisions in IWE-2310(a) are not approved for use for VT-1 and VT-3 examinations.
- Dominion comment: For ltem E1.12 the limitation requires that the VT-3 examination method be used instead of a general visual examination.
Dominion will perform this examination using the visual VT-3 method using the examination provisions of IWA-2200.
(H) Limitation (bolting examinations per ltem E l. l l while disassembled) does not apply to ltem E l.12.
(I) Limitation (ultrasonic examination acceptance criteria of IWE-3511.3) does not apply to ltem E l.12.
The 2001 Edition through the 2003 Addenda Table IWE-2500-1, Category E-A, ltem E l.12 with applicable notes, is proposed for use with the required 10 CFR 50.55a(b)(2)(ix) limitations noted above.
Implementation of Related Requirements Table 2500-1, Category E-A, ltem number E l.12 as modified by 10 CFR 50.55a(b)(2)(ix)(F) and (G) are the related sections of the requested portion of the 2001 Edition through the 2003 Addenda of ASME Section XI.
The provisions of 10CFR50.55a(b)(2)(ix)(G) requires that a VT-3 examination be performed for ltem number E1.12, when using the 2001 Edition through the 2003 Addenda of ASME Section XI. Additionally, the provisions of IWA-2200 and IWA-2300 shall be used for the VT-3 examination method and examiner qualification as opposed to any "owner-defined program per 10CFR50.55a(b)(2)(ix)(F) and (G).
These limitations for implementation of the ASME Section XI Code would be complied with.
The following clarification of Dominion's VT-3 examination and qualification procedures are provided.
- 1)
The North Anna and Surry VT-3 examination procedure for Category E-A, ltem number E l.12 is based upon IWA-2200 and the acceptance criteria of IWE-3510 of the 1992 Edition with the 1992 Addenda of ASME Section XI.
The examination requirements are essentially the same. Some of the later Code edition requirements are already incorporated in the Dominion VT-3 procedure, if more conservative.
As such, the VT-3 examination procedure will not be modified due to this request. (Attachment 2 provides a comparison of the applicable code requirements found in IWA-2200 and IWE-3510 associated with the VT-3 examination, and provides an assessment of the Dominion procedure requirements.)
- 2)
The written practice for North Anna and Surry VT-3 examination personnel qualification was previously updated by approved request to the requirements of Page 4 of 5
Serial No.06-856 Docket Nos. 50-2801281 and 50-3381339 IWA-2300 in the 1998 Edition through the 2000 Addenda of ASME Section XI.
These requirements are essentially the same as the requested 2001 Edition through the 2003 Addenda of ASME Section XI. As such, the written practice for the VT-3 examination method will not be modified due to this request.
(Attachment 3 provides the differences in the applicable code requirements found in IWA-2300 associated with VT-3 examiner qualification/certification.)
All other provisions of the 1992 Edition with the 1992 Addenda of ASME Section XI as modified by approved relief request in the Containment IS1 Plan remain in affect for the first ten-year Containment IS1 Interval.
Duration of Proposed Request Approval is requested for the first Containment IS1 (IWE) ten-year interval for North Anna Units 1 and 2 and Surry Units 1 and 2.
