Subject:

Waterford 3 SES Docket No. 50-382 License No. NPF-38 Reporting of Licensee Event Report

Dear Sir:

Attached please find revised Licensee Event Report (LER) Number LER-86-011-01 for Waterford 3. This LER has been revised because it has been determined that deviations to Appendix R requirements for the fire barriers cor taining the 228 seals identified to have a sleeve type configuration as described in the LER are not required. The LER stated that Appendix R deviations would be pursued for these penetration seals. However, further evaluation by Louisiana Power & Light Cocpany (LP&L) has determined that it is not necessary to pursue Appendix R deviations. Enclosure 1 to Generic Letter 86-10 specifies that (1) when a barrier ; s not completely sealed to its l required rating, an evaluation must be performed by a fire protection engineer to assess the adequacy of the barrier, and (2) when the evaluation l demonstrates that the barrier is sufficient to withstand the attendant hazards, the matter may be handled internally.

A conference call between representatives of LP&L and the Office of Nuclear l Reactor Regulation was conducted on December 30, 1986, to discuss the necessity of pursuing the aforementioned deviations from the Appendix R requirement for 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> rated fire barriers. It was agreed during the call that Enclosure 1 to Gene.ric Letter 86-10 provides the mechanism to address the effectiveness of tne fire barriers internally, and therefore, Appendix R deviations would not be required.

Very truly yours, h
