Status of Actions in
Response
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).

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.
