During an
ISI inspection of the component cooling system, it was discovered that several of the surge tank support
stiffener plates were missing due to a design change that was never fully implemented. This condition creates a question as to the adequacy of the tanks to withstand a seismic event. This deficiency affects both trains of component cooling on Units 1 and 2. The problem will be corrected on Unit 1 while it is in its refueling outage. Work on the Unit 2 "A" train is currently ongoing, making that train of the component cooling system inoperable, therefore, putting the plant in a
72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> LCO. When work on the "A" train is completed, they will exit the LCO, but re-enter it when work begins on the "B" train.
Licensee will notify the NRC Resident Inspector, the State and local agencies.

The subject EN #40359 was made on 11/28/03. Following additional review by the licensee, this event was determined to not meet the reportability requirements of 10 CFR 50.72. The event was determined to not result in a condition that could have prevented fulfillment of a safety function, as the tank supports were analyzed to withstand a seismic event. In addition, the event did not result in the plant being in an unanalyzed condition. The condition did not prevent the fulfillment of a safety function or system that is needed to remove residual heat or mitigate the consequences of an accident.
The licensee plans to notify the NRC Resident Inspector.
