Reference:

Dr. Murley:

Pursuant to.10 CFR 50.90, Commonwealth Edison proposes to amend Appendix A, Technical Specifications to Facility Operating Licenses.DPR-29.and DPR-30 for the Quad C1 ties-Nuclear Power Station; The proposed Technical l Specification. reflects a'HPCI area; fire protection sy"cem modification which replaces spot-type heat detectors with a< linear heat detector. -Commonwealth Edison initiated the development-of the. modification.due to the spurious actuation of the sprinkler system in the HPCILroom which rendered thetHPCI system inoperable for a period of time. The modification 1s-intended.to -

provide additional reliability of the fire protection system._ The proposed .

amendments are delineated in Attachment 1 and further discussed in~ Attachments 2 and 3.' -)

Since November 28, 1989, the HPCI fire detection system _for Units 1 and 2 has been removed from service ~to prevent any further spurious. operation ,

'by the fire protection system. Compensatory measures have been established <

since the removal of.t.he-system from service. The modification design work will be completed in-late July and therefore Commonwealth Edison requests your Staff's approval of the proposed amendment no later than October 12, 1990, h0[ bo  ;[
