INDICATION OF LEAKAGE
"Inspection of the pressurizer bottom nozzles in accordance with the Alloy 600 Program during Refuel 12 identified a wet stain on heater sleeve C1, and a nozzle with a white substance extruding from a portion of the penetration on heater sleeve C3. The substance could not be verified at the time, and further investigation is required to determine if the substance is boron on heater sleeve C3. This condition constitutes a degradation of the RCS Pressure Boundary and is reportable pursuant to 10 CFR 50.72(b)(3)(ii)(A)."
The NRC Resident Inspector will be notified of this event by the licensee.
