SUBJECT:

(a) Letter from Mr. J. A. Tiernan (BG&E), to NRC Document Control Desk, Request for Relief from Replacement Requirements in Section XI of the ASME Boiler and Pressure Vessel Code, Articles IWA-7210, IWC-7600, IWD-7600, and IWF-7600, dated May 11,1987 (b) Letter from Mr. J. A. Tiernan (BG&E), to NRC Document Control Desk, Request for Exemption from Inservice Inspection Requirements in 10 CFR 50.55a(g), dated May 11,1987.
Gentlemen:
We hereby withdraw cur request for relief (Reference a) and our request for exemption (Reference b). We regret any inconvenience our requests may have caused.
When we made our requests we estim..d there may have been up to several hundred fasteners (nuts, bolts, and threaded rods) installed at Units I and 2 without proper documentation.
If our estimates were correct, then we would have desired to conduct a sampling and testing program to ensure those fasteners were adequate and could remain in place.
This formed the basis for our requests.
Subsequent to our requests, we completed the review of over 30,000 Maintenance Requests and found only 61 cases of fasteners installed without proper documentation. The sampling and testing program outlined in our requests could not apply to such a small number of cases. Instead, we replaced each fastener with one that had proper documen-tation. Licensee Event Report 87-09, Revision 1 provides more detailed information.
