EN Revision Text: AUTOMATIC REACTOR TRIP DUE TO LOW STEAM GENERATOR LEVEL
"At 0526 [CST] on 02/15/2021, Unit 1 automatically tripped due to low steam generator levels. The low steam generator levels were due to loss of Feedwater pumps 11 and 13 (cause unknown).
"Auxiliary Feedwater and Feedwater Isolation actuated as designed. All Control and Shutdown Rods fully inserted. No primary or secondary relief valves opened. There were no electrical problems. Normal operating temperature and pressure (NOT/NOP) is 567 degrees F and 2235 psig.
"There were no significant TS LCOs entered.
"This event was not significant to the health and safety of the public based on all safety systems performed as designed. Unit 2 was not affected. Decay heat removal is being controlled via Steam Dumps. [Auxiliary Feedwater is supplying water to the Steam Generators.] Offsite power is in the normal electrical lineup.
"The NRC Resident inspector has been notified."
Unit 2 was not affected and remains at 100% power.
