Crew should perform Plant Transient Response (PTR) and determine that a runback condition exists but due to ICS being in manual it is not occurring.

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

The BOP reports expected AUTO Runback did not occur, and monitors RCS pressure and inventory and inserts Control Rods as needed.

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

SRO should enter AP/1/A/1700/001 (Unit Runback)

NOTE NIs should NOT be calibrated per guidelines contained in OP/1/A/1102/004 (Operation at Power) due to actual power re

-distribution within the core as a result of a dropped/misaligned rod.

3. Verify Rx is critical.

Crew Response:

When the Statalarms are received, the candidates should utilize the "Plant Transient Response" (PTR) process to stabilize the plant, which should include: o ICS to HAND (Feedwater Masters and Diamond) o Inserting Control Rods as needed to control RCS pressure (Performed by the BOP) o Decreasing or re

-ratioing feedwater to control Reactor power and delta Tcold (Performed by the OATC (CT-1) SRO may direct the OATC to perform the actions of the ARG for 1SA

-02/A-3 statalarm, but probably will move directly from PTR to AP/28.

ARG for 1SA

-02/A-3 3.1. Ensure reactor power is reduced below the flux to flow minus imbalance trip ratio.

3.2. Ensure

feedwater demand re

-ratios properly.

EXAMINER NOTE: This failure will cause FDW flow to re

-ratio. IF the crew immediately recognizes it is an instrument failure and not an actual loss of flow they may choose to adjust FDW and therefore prevent high delta Tc from being established causing high Quadrant Power Tilt values. The SRO should direct a band for delta Tc of 0

+2 degrees as he establishes bands for parameters being manually controlled.

RCS Boration from CBAST in Automatic Time Position Applicant's Actions or Behavior BOP

OATC OP/1/A/1103/004A, Encl 4.1 (RCS Boration From CBAST With CBAST Pump) During this activity, the BOP will be performing Peer Checks as required and responding to direction from the SRO when needed.

NOTE: OP/1/A/1103/004 (Soluble Poison Control) provides guidance for RCS boron change calculation or computer calculation for determining required volumes. (R.M.)

LDST temperature may increase from adding CBAST because of CBAST temperature.

50 gal flush must be performed to ensure calculated volume of CBAST is added. DW. {16} If RCS boration is for a Forced Outage, targeted boron should not exceed 200 ppm above the required SDM to prevent excessive RCS boration. The 200 ppm above required SDM will borate the Pressurizer to the required SDM since the Pressurizer usually lags the RCS by approximately 200 ppm.

Section 2: Procedure

2.1 Determine

required volume of CBAST needed for desired RCS boron changes. (R.M.)

50 gal of DW added due to flushing must be included in determination Volume required ____________gallons.

2.2 CBAST

required volume approved (SRO). (R.M.)

NOTE: Placing an idle Letdown Filter in service c60 gals of water to RCS at different boron (negligible for RCS boration). (R.M.) 2.3 IF two Letdown Filters are available, perform the following:

Ensure open 1HP

Ensure open 1HP-18 (1B LETDOWN FILTER INLET)

2.4 Ensure
