to SWSOPX Violations, Deficiencies, and Unresolved Items Xnspection Report 50-244/91-201 R.E. Ginna Nuclear Power Plant Docket No. 50-244

Dear Mr. Johnson,

In Reference (a)

RG&E committed, by the end of the third quarter 1992, to provide an updated status of RG&E actions taken or planned irn response to the items identified in Appendix A of Reference (b).

Appendix A of Reference (b) identified a total of 15 items; 4 were identified as Deficiencies, 5 were identified as Unresolved items, and 6 were identified as Observations.

Three, of. these resulted in Violations as documented in Reference (c).

Since.the issuance of Reference (b) and the subsequent Notice of Violations, Reference (c),

RG&E has expended a significant effort toward resolution of the open issues identified during the SWSOPI Team Xnspection.

As acknowledged by the NRC in Reference (c), all identified items, weaknesses, and observations related to the SWSOPI're being tracked in our Commitment and Action Tracking System to.assure formal resolution of these matters.

Since the completion of the team inspection, RG&E has been tracking the progress of 62 COmrtlitmentS Oi aCticn itesssS reSulting direCt j frOm tahe SWSOPX Or related to it.

Currently, 35 of these have been closed by RG&E and 27 remain open in,various stages of completion.

In addition, during the week of August 17, 1992, NRC staff performed a follow-up inspection during which RG&E provided information and status of RG&E actions for the three violations (91-201'01, 91-201-11, and 91-201-14) and two of the unresolved items (91-201-04 and 91-201-15).

Since NRC documentation of the results of. thatinspection (designated 50-244/92-012) has not as

yet, been
received, this letter provides the status of all the 15 deficiencies, unresolved
items, and observations identified in Appendix A of Reference (a).

In a lett~~, Reference,(d),

RG&E indicated that the existing service water s'st: em flow balance to the emergency diesel generator coolers was satisfactory and that no change was warranted at this time,

however, the overall SWS flow balance continues;.to be planned for the 1993 outage.

In addition, by Reference (e)
