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

(91-201Ž01, 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).('Tt210210045

ATTACHMENT

A In response RG&E committed to 1)evaluate/test, the diesel generator cooler performance

and determine the optimum flow[R01958];2)enhance the analytical

modeling and capability

of the existing hydraulic model so that an analytical

basis and test specification

for the re-balance

of the SWS is available prior to the 1993 refueling outage[R01959];and 3)conduct testing as required during the 1993 outage to confirm the analytical

results of the enhanced model and to set optimal flows"for each SW cooler so that.the SWS flow balance will be optimized when the plant returns to power following" the 1993 outage.[R01960]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)RG&E committed to perform pilot thermal performance

testing of the diesel generator coolers during the summer of 1992 based upon the existing system instrumentation

[R02438], evaluate these results[R02440], and commence periodic thermal performance

testing during the summer of 1993 to coincide with the highest lake water temperatures

[R02439].The'pilot testing has been completed and the results are being reviewed by engineering

and plant staff.Page-7
