Specify in Abstract below or in ANALYSIS OF SAFETY SIGNIFICANCE Upon the trip of the SGFP supplying the SGs, AFW automatically actuated. Subsequently, the 3A SBSGFP was started to maintain SG levels and AFW was restored to operable standby status. The manual RPS actuation was conservatively employed to prcvide additional shut down margin when AFW actuation lowered RCS temperature. The unit was not critical in Mode 3 when this event occurred. The systems discussed in this report operated as designed. Therefore, the safety significance of this event is very low.
CORRECTIVE ACTIONS
Corrective actions are documented in AR 1856476 and include the following:
Implement and assess the effectiveness of the improvement plan to reinforce operational standards.
