Valid Reactor Trip and Manual Initiation oValid Reactor Trip and Manual Initiation of Auxiliary Feedwater While in MODE 3</br>At 1042 on 12/12/2008, while in Mode 3, a valid reactor trip signal was generated during I&C maintenance activities on intermediate range nuclear instrument SENI0036. This resulted in a feedwater isolation signal. Reactor Operators manually started both motor driven auxiliary feedwater pumps to maintain steam generator levels. These pumps were started prior to receiving an Auxiliary Feedwater Actuation. Plant is stable in Mode 3. Normal feedwater supply has been restored. The cause of the reactor trip is understood.</br>All systems functioned normally in response to plant conditions.</br>The NRC Resident Inspector has been notified. The NRC Resident Inspector has been notified.  +
