----------- [ Current event for NC_Brunswick_1 ]

20190612 | NC_Brunswick_1 | HIGH PRESSURE COOLANT INJECTION (HPCI) INOPERABLE |
https://www.nrc.gov/reading-rm/doc-colle...ml#en54116

"At 2127 EDT on June 12, 2019,
during routine testing, the HPCI turbine experienced an overspeed trip
and then subsequently restarted and ramped to the required speed.

 As a result, the response time of the system exceeded the 60-second acceptance criteria,
thereby rendering the system inoperable.

This condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D).

The Reactor Core Isolation Cooling (RCIC) System and Automatic Depressurization System (ADS) are operable.

"The safety significance of this event is minimal.

Troubleshooting activities are in progress.

"There was no impact on the health and safety of the public or plant personnel.
The NRC Resident Inspector has been notified."

20190612 | TN_WattsBar_1 | LOSS OF CONTROL ROOM EMERGENCY AIR TEMPERATURE CONTROL SYSTEM |
https://www.nrc.gov/reading-rm/doc-colle...ml#en54112

"At 0849 (EDT), a significant air leak on an inline air filter was identified.
At 0908, the leak on the filter was isolated. 
[ duct taped? ]

A subsequent review of this situation determined that this air leak impacted operation
of the A Train of the Control Room Emergency Air Temperature Control System (CREATCS)
which is required to be operable in accordance with Technical Specification 3.7.10.

At the time of this event, the B Train of CREATCS was out of service for planned maintenance.

"With both trains of CREATCS out of service, both Watts Bar Units entered a condition that could have prevented fulfillment of a safety function.

This condition was terminated when the leaking air filter was isolated.

This event is being reported pursuant to 10 CFR 50.72(b)(3)(v)(D).

"NRC Resident Inspector has been notified."
