OATC reports to the SRO reactor power level and direction of movement.

The BOP reports no valid runback and monitors RCS pressure and inventory.

OATC takes ICS to MANUAL and both FDW controllers to HAND.

The OATC will adjust FDW and/or control rods as necessary to restore reactor power to the desired control band.

SRO may direct the OATC to perform the actions of the ARG for 1 SA-02/A-4 statalarm, but probably will move directly from PTR to AP/28.

ARG for 1SA-02/A-4 SRO/OATC 3.1. Ensure reactor power is reduced below the flux to flow minus imbalance trip ratio.

Crew Response:

SRO/OATC If the OATC notices that RCS pressure and PZR level are decreasing at a rate that is obviously in excess of make-up capability, he may choose to manually trip the reactor prior to the automatic trip. (OMP 1-18)
