Manual attempts to restore level were not effective. Steam generator level decreased to the low level trip setpoint.</br>Auxiliary feedwater systems automatically started due to low post trip steam generator levels. This includes the Steam Driven Auxiliary Feedwater Pump. The steam discharge of this pump is considered to a gaseous release due to trace amounts of tritium in the secondary system. These trace amounts are well below limits. The pump was shutdown after 16 minutes of operation, terminating the discharge. The Rad Waste & Effluents Section will assess the impact during the event response review.</br>Plant is currently stable in Mode 3 with steam generator levels restored to post shutdown values. The steam dumps and main unit condenser are available for heat removal. All normal and emergency busses are energized from offsite power.</br>The NRC Resident Inspector was notified of the event by the licensee.tor was notified of the event by the licensee. +
