RANCHO SEC0 NUCLEAR GENERATING STATION 7
UNIT N0. 1 TMI ACTION PLAN ITEM II.E.1 On November 17, 1980, the Sacramento Utility District submitted information on our upgraded auxiliary feedwater system. A revised system description, Document 15-1120589-01, and several engineering drawings were submitted on September 8,1981, to provide information on the safety grade initiation and flow indication, which are part of this system.
The information provided in the September 8, 1981, letter should be considered the final design of the upgraded auxiliary feedwater system.
Attached to this letter is a report, " Auxiliary Feedwater System Upgrade Reliability Analysis for the Rancho Seco Nuclear Generating Station Unit No.1."
This report provides the reliability assessment for the upgraded auxiliary feed-water system as requested by your staff. We feel this information provides the necessary input for your final review of our upgraded auxiliary feedwater system.
If we can provide any additional information, please advise.
