Crew Response:

OATC

• When the Statalarms are received, the candidates should utilize the Plant BOP Transient Response (PTR) process to stabilize the plant, which should include:

OATC 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 (CT-1) delta Tcold (Performed by the OATC (CT-1)

SRO/OATC 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.

SRO The SRO should direct a band for delta Tc of 0 +2 degrees as he establishes bands for parameters being manually controlled.

SRO directs performance of AP/1/A/1700/028, ICS Instrument Failures. (see next page)

Description:

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

• Main process piping between CBAST and LDST contains 25 gallons of 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 OATC 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 can change RCS boron by adding 60 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-17 (1A LETDOWN FILTER INLET)

• Ensure open 1HP-18 (1B LETDOWN FILTER INLET) 2.4 Ensure open 1CS-64 (CBAST OUTLET).

2.5 Open 1CS-72 (CBAST Header to Letdown Filter Inlet). (A-2 LDST Hatch area)

1. CT-1 Start Main Vacuum Pumps Start Main Vacuum Pumps prior to a Main Turbine or Main Feedwater Pump trip on low vacuum.

2. CT-2 (BWOG CT-1) Trip RCPs Trip RCPs within two minutes of RCS SCM reaching zero.

3. CT-3 (BWOG CT-27) Start the Outside Air Booster Fans Start the Outside Air Booster Fans within 30 minutes of the LOCA to control the Control Room radiation levels due to ingression of airborne fission products during a LOCA event.
