AUTOMATIC REACTOR TRIP
"At 0114 [CDT] on April 04, 2020 the plant was in Mode 1 at 100 percent power when a Digital Feedwater Trouble alarm was received unexpectedly. Operators identified a full feedwater demand signal and lowering level in the 'C' Steam Generator. At 0115 a Reactor Trip signal for Low Steam Generator Level was received. All systems responded as expected. A Feedwater Isolation signal was received due to the reactor trip with RCS average temperature less than 564 degrees Fahrenheit. Auxiliary Feedwater started on a valid actuation signal to restore and maintain Steam Generator levels. The Plant is being maintained stable in Mode 3 with no complications.
"The NRC Resident Inspector has been notified of the Reactor Trip."
All control rods fully inserted from the reactor trip signal, and decay heat is being removed via the Auxiliary Feedwater and Steam Dump Systems.

OFFSITE NOTIFICATION
At approximately 0930 EDT on April 4, 2020, the New Hanover County Deputy Fire Marshall was notified per state code requirements that the fire alarm system and accompanying fire pumps encompassing the fuel manufacturing operation (FMO) were placed on backup power due to a planned power outage. Additional compensatory measures were enacted. Power was restored at approximately 1800 EDT on April 4, 2020. Because the New Hanover County Deputy Fire Marshall was notified, a concurrent notification to the NRC Operations Center is being made per 10 CFR 70, Appendix A(c).
