"This is a non-emergency notification from Waterford 3.
"10 CFR Part 21 Notification - Defect of Westinghouse 7300 Process Analog Control System circuit cards
"On August 14, 2018, Entergy Operations, Inc. (Entergy) completed an evaluation of a deviation at Waterford Steam Electric Station, Unit 3 (Waterford 3) which concluded the condition constitutes a defect pursuant to 10 CFR Part 21. The Waterford 3 Site Vice President was notified of the result of this evaluation on August 21, 2018. An interim report stating that an evaluation of this deviation was in progress was submitted to the NRC on July 5, 2018 (Entergy letter W3F1-2018-0040, ADAMS Accession Number ML18186A694).
"Three Westinghouse 7300 Process Analog Control System (PAC) circuit cards were identified to be failed due to failed hex inverter chips. Some of these cards were installed in applications which support the Ultimate Heat Sink (UHS) at Waterford 3. These PAC cards use Texas Instruments Part Number SN74LS04N, W113 hex inverter chips. The circuit card types of concern are Analog Comparator model number 2838A32G01, Control Board model number 2838A30G011, and Prom Logic model number 2838A33G01. Entergy concluded that this condition could have prevented the UHS from performing its safety function and thus could have created a substantial safety hazard.

"At 0745 EDT on August 24, 2018, the Active Seismic Monitoring System failed a planned surveillance test and was declared inoperable. Compensatory measures to provide alternative methods for event classification of a seismic event have been implemented in accordance with the Fermi 2 Emergency Plan procedures. The compensatory measures include the use of information provided by the United States Geological Survey (USGS) to confirm if an earthquake has occurred within a 100 mile radius.
"The loss of the Active Seismic Monitoring System is reportable to the NRC within 8 hours of discovery in accordance with 10CFR50.72(b)(3)(xiii).
"No seismic activity has been felt onsite and the USGS recorded no seismic activity in the area.
"The NRC Resident Inspector bas been notified."
* * * RETRACTION FROM JEFF GROFF TO VINCE KLCO ON SEPTEMBER 13, 2018 AT 1524 EDT * * *
"After further review the Active Seismic Monitoring system was removed from service for planned maintenance for a duration less than 72 hours with appropriate compensatory measures established. Therefore, no major loss of emergency assessment capability occurred. In addition, the surveillance tests were re-performed and the Active Seismic Monitoring System was declared Operable. Therefore, no reportable condition existed and EN 53562 reported on August 24, 20I8 is being retracted.
"The NRC Resident Inspector has been notified."
