Subject:

NRC Independent Measurements The NRC will perform an independent verification inspection at Beaver Valley Nuclear Power Station, Unit 2 using the NRC Nondestructive Examination (NDE)

Van and contractor technicians under NRC direction. Construction activities and materials will be sampled through nondestructive examinations as a supple-ment to our existing inspection efforts. Similar nondestructive examinations by the NRC have been performed on a routine basis at yours and other construc-tion sites.

The selection will be made from structural supports, pipe hangers, and electrical tray supports. Selected welds in the Preservice Inspection (PSI) Program will be re-examined in conjunction with a review of your FSI data. Some concrete will be tested. We will update our NDE proce-dures to be consistent with your committed codes and standards. All documenta-tion supplied by your staff will be returned, upon request, at the conclusion of the inspection.
