VALID ACTUATION OF EMERGENCY FEEDWATER "On 3/2/2016, [at] 1312 hours EST, while in the process of a plant cooldown, a valid actuation of the emergency feedwater system (EFW) occurred when B steam generator levels were reduced to 20 [percent]. The lowering level was a result of the unanticipated tripping of the start up feed pump on low condensate storage level while it was the feed source to the steam generators. The start up feed pump was restarted and feed flow had been restored when the actuation took place. The EFW flow was secured per procedure and the start up feed pump remains the feed source to the steam generators. "This is reportable under 50.72(b)(3)(iv)(A). "The licensee notified the NRC Resident Inspector."
