r I This document details the planned scope of preservice examinations associated with the Surry Unit 1 Steam Generator Replacement Project. These examinations I will be performed in accordance with the requirements of Section XI of the ASME Boiler and Pr...:ssure Vessel Code, 1974 Edition with Addenda thru the Summer 1975, to the extent practical with access provided and limitations of component geometry. The intent of these examinations is to pr:..ovide preservice baseline data for those new ASME Class 1 and 2 pressurp-retaining co~ponent (and their supports) welds associated with the steam ge~erator r~lacement. The NDT work that will be performed by construction personnel as:. required by the final design controlling procedures is not within the scope of this plan.

Qualification of NDT personnel, materials and equipment will be available prior to the start *of examinations. Examination procedures to be used wi_ll be those contained in the Vepco Nondestructive Test Manual and/or approved vendors' procedures to be determined prior to the actual testing.

The examinations outlined in the enclosed tabulations have been developed from the steam generator replacement design packages. Specific locations

• on isometrics drawings of some of the welds cannot be determined from the information therein; and thus will be field located by the NDT personnel during performance of the examinations and indicated on the appropriate drawings.

With respect to ASME Class 2 components, the welds specified in the plan may be substituted by other welds as long as the requirement of IWC-2411 are complied with.
