Alternative Requirements for Preservice Examination Volumetric Surface Configuration Requirements Plant Site-Vogtle Electric Generating Plant (VEGP) - Units 3 and 4 Unit:
Interval-Applies to construction and preservice inspection intervals.
Interval Dates:
Requested Date for Approval is requested by 1/21/19 to support performance of preservice inspection activities prior to the Class 1 hydrostatic test.
Approval:
ASME Code Components ASME Class 1 Piping and Components Affected:
Applicable Code Edition ASME B&PV Code,Section III, 1998 Edition through the 2000 Addenda (code of record).
and Addenda:
ASME Section III NB-4424.2 (a) requires that the surface finish shall be 6.3 Ra or better for a distance of at least 2t (where t equals nominal wall Applicable thickness) plus 4 in., or 6 in., whichever is greater (Fig. NB-4250-2 or Code Fig. NB-4250-3), from the edge of the weld crown on at least one side of Requirements: the weld where an ultrasonic examination is required.
As noted in Fig. NB-4250-2 and NB-4250-3, this distance is required to be free of interferences.

ND-18-1014 Proposed Alternative VEGP 3&4-PSI/ISI-ALT-10 in Accordance with 10 CFR 50.55a(z)(1) -
Alternative Requirements for Preservice Examination Volumetric Surface Configuration Requirements The requirements for surface finish, surface finish distance, and distance for which any hanger or attachment (or any other interference) can be made, is required to be 2t (where t equals nominal wall thickness) plus 4 inches, or 6 inches, whichever is greater as described in ASME Section III NB-4424.2(a) and shown in ASME Section III NB-4250-2 for ultrasonic examinations.
VEGP Units 3&4 contain interferences where these requirements cannot be met. Figure 1 is an ASME Fig. NB-4250-2 excerpt which illustrates the interference requirement.
Figure 1: ASME Section III Figure NB-4250-2 Excerpt Reason for Request:
The purpose of this distance requirement is to assure the examination area is adequate to perform a volumetric examination from the outside diameter (OD) for component-to-pipe and pipe-to-pipe welds.
Other examination configurations exist that would allow an adequate examination in accordance with ASME Section XI. One specific example is instrumentation bosses, near the AP1000 Steam Generator Hot Leg Safe End-to-Pipe welds, which are within the distance required in ASME Section III NB-4424.2 (Shown in Figure NB-4250-2). Figure 2 shows the example configuration and the method used to verify that the ASME coverage requirements are met with an interference in place.

ND-18-1014 Proposed Alternative VEGP 3&4-PSI/ISI-ALT-10 in Accordance with 10 CFR 50.55a(z)(1) -
Alternative Requirements for Preservice Examination Volumetric Surface Configuration Requirements Figure 2: Method Utilized to Conclude Essentially 100% of the ASME Section XI Volume is Examined for the Steam Generator Hot Leg Safe End-to-Pipe welds.
Proposed Alternative:
For cases in which there is less than the distance of 2t plus 4 in. or 6 in.,
whichever is greater, an inspectability evaluation will be conducted to ensure that adequate examinations can be performed. The inspectability report will document the percent coverage that can be obtained from the applicable examination area (i.e., ID, OD, or both) and conclude that essentially 100% of the ASME Section XI inspection volume is obtained. This will establish the Proposed method for future inservice inspections.
Alternative For configurations that do not meet those described in NB-4424.2(a) and and Basis shown in Figure NB-4250-2 and Figure NB-4250-3:
for Use:
(a) The requirements of Figure NB-4250-1 shall be met.
(b) The Owners Design Specification shall describe the configuration and surface finish required for preservice inspection in lieu of the configuration shown in Figure NB-4250-2 or Figure NB-4250-3 and surface finish described in NB-4424.2(a).
(c) The Certificate Holder (with agreement of the Owner or Owner Designee) shall verify and document that the required preservice inspection can be performed with the proposed configuration and surface finish.

ND-18-1014 Proposed Alternative VEGP 3&4-PSI/ISI-ALT-10 in Accordance with 10 CFR 50.55a(z)(1) -
Alternative Requirements for Preservice Examination Volumetric Surface Configuration Requirements (d) Use of this alternative shall be documented in the applicable VEGP Units 3 and 4 Design Specifications and N-5 Data Reports.
Basis for Use:
For volumetric examination surface configurations that do not meet NB-4424.2(a), which reference Fig. NB-4250-2 and NB-4250-3, an inspectability evaluation is performed and documented to ensure that essentially 100% of the ASME Section XI volumetric examination coverage is obtained. If essentially 100% volumetric examination coverage is not obtained, this alternative shall not apply.
The proposed alternative ensures that essentially 100% of the ASME Section XI preservice inspection volume is obtained and future inservice inspection coverage requirements will be met; therefore, this proposed alternative provides an acceptable level of quality and safety in accordance with 10 CFR 50.55a(z)(1).
