Subject:

Quad Cities Nuclear Power Station Unit 2 NRC Generic Letter 96-06 Status

Reference:

(a) John Hosmer Letter to USNRC, Response to Generic Letter 96-06 " Assurance of Equipment Operability and Containment Integrity During Design-Basis Accident Conditions,"

dated January 24,1997.

(b) NRC Memorandum to Division of Reactor Safety l Division Directors from G. M. Holahen, dated January 24,1997.

On May 2,1997, Comed provided a response to Generic Letter 96-06, " Assurance of Equipment Operability and Containment Integrity During Design Basis Accident I

! Conditions." The Generic Letter required licensees to evaluate equipment operability I 2

and containment integrity during design basis accident conditions. In accordance with 10CFR50 Appendix B, Criterion XVI, Quad Cities has developed a corrective action plan for s esolving the long-term issues raised by Generic Le - " 06. To support power operation, Quad Cities has completed operability asr. ~

an affected 7

h equipment in accordance with Generic Letter 91-18. These operability assessments address the concerns raised in Generic Letter 96-06 and conclude affected components will remain operable during design basis accide a conditions. Quad Cities Unit 2 is scheduled to return to service following refueling on May 27,1997. Consistent with the

, NRC's staff guidance associated with plant startup relative to Generic Letter 96-06,

[ Reference (b)], Quad Cities plans on restarting Unit 2 with an open operability assessment associated with Generic Letter 96-06. This operability assessment will be closed-out consistent with the implementation of the long-term corrective actions for resobring Generic Letter 96-06 issues.

} inside the drywell and is not used during operation. Operating procedures have been revised to require that this volume be drained prior

to startup from every refuel outage or any other outage if the piping was valved into service.

In Reference (a) Quad Cities described that eight (8) penetrations were determined to be L susceptible to thermally induced pressurization conditions. Currently, there remains only one penetration which has not been resolved. Delivery of a relief valve is expected to be beyond the projected outage completion date. The valve will be installed at the first outage of sufficient duration following receipt of the' valve. Resolution of each penetration is enclosed in Attachment A to this letter.
