ATTACHMENT 2 IDENTIFIED CODE RECONCILIATION FOR A2R20 SNUBBERS

Braidwood IR 4214087 is a follow up to IR 4201815 and documents that the receipt documentation for snubbers 2SD23098S, 2Sl18049S, 2SI05013S, and 2AB23034S cannot be retrieved through plant records. Currently, all attempts to locate the receipt inspection paperwork for these four snubbers remains unsuccessful. The snubbers in question have been stored and controlled in either the Braidwood or Byron warehouse and through the Passport inventory system. They were all successfully functionally tested prior to installation during A2R20.

Certificate of Conformance and code data reports were obtained for these snubbers and documented compliance with Class 1 requirements to ASME Code Section Ill, Subsection NF, Division 1 of the 1977 Edition Winter 1977 Addenda. The applicable Braidwood Code of Construction is ASME Code Section Ill, Subsection NF, Division 1 of the 1974 Edition Summer 1974 Addenda. Thpri:>fnr"'. ~ r.nrle reconr.iliation i!':. required to resolve any varii:mce that may exist with the two code years menti.oned here. This condition was entered in the Braidwood Corrective Action Program (CAP) for identification and resolution. Again, reference IR 4214087 and IR 4201815 for complete details.
