TECHNICAL SPECIFICATION SHUT DOWN DUE TO CHEMISTRY LIMIT EXCEEDED
"At 0200 Central Daylight Time on 10/21/2018, Browns Ferry Nuclear Plant Unit 3 commenced a reactor shutdown as required by the Technical Requirements Manual Limiting Condition for Operation 3.4.1 Coolant Chemistry Condition D due to conductivity greater than 10 micro mho/cm at 25 degrees Celsius. The required action for this condition is to immediately initiate an orderly shutdown and be in Mode 4 as rapidly as cooldown rate permits. This event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(i).
"There was no impact on the health and safety of the public or plant personnel. The NRC Senior Resident Inspector has been notified."
* * * RETRACTION AT 1719 EST ON 12/13/2018 FROM NEEL SHUKLA TO MARK ABRAMOVITZ * * *
"ENS Event Number 53678, made on 10/21/18, is being retracted.
"NRC notification 53678 was made to ensure that the four-hour non-emergency reporting requirements of 10 CFR 50.72 were met when the licensee discovered a condition requiring shut down of a reactor.
"10 CFR 50.72 requires a report in accordance with 50.72(b)(2)(i) for any Technical Specifications (TS) required reactor
shutdown. NUREG-1022 only specifies TS applicability and makes no mention of a Technical Requirements Manual (TRM) required shutdown. Because the shutdown comes from the TRM and not the TS as discussed in 10 CFR 50.72 and
NUREG-1022, an EN was not required.
"TVA's evaluation of this event notification is documented in the corrective action program.
"The licensee notified the NRC Resident Inspector."
