3.0 PERSONNEL INDOCTRINATION 3.1 Definitions

• Auxiliary Pressurizer Spray (APS) - A boron precipitation mitigation method that diverts a portion of LPI flow to the pressurizer spray nozzle.

Providing flow to the pressurizer builds a height of water in the core region. When an adequate height of water is developed, reverse flow through the core is initiated. This method is only effective if spray flow exceeds core boil-off and is started early enough to allow a liquid level to be established prior to reaching actual core solubility limits.

• Delta Boron - The difference between Expected RB Sump Concentration and actual measured RB sump boron concentration (boronometer, grab sample) after ECCS suction transfer.

• Dump To Sump (DTS)- A boron precipitation mitigation method that aligns the DH drop-line to the RB sump through an idle LPI train. This alignment redirects the ECCS injection being lost though a break in the RCS cold leg through the core region. This redirection occurs because the DH drop-line connects to the hot leg at an elevation lower than the RCS cold leg piping.

• Expected RB Sump Concentration (SumpExp) - A calculated value of RB sump boron concentration assuming even mixing of the RCS, CFTs, and BWST located in the RB sump.

3.2 Responsibilities The TSC Accident Assessment Team is responsible for monitoring plant conditions and determining when boron precipitation mitigation is required.

EM-2256 Rev. 10 Page 4 of 26

3.3 Limits And Precautions APS is the preferred method of boron precipitation mitigation, and should be used if acceptable plant conditions exist. This preference is due to the significant adverse impact on ECCS performance if DTS is improperly implemented, and the need to stop a train of ECCS to perform the DTS alignment.

If required for A Train APS effectiveness DHV-5 may be closed provided HPI has been established.

• Grab samples should be taken from the recirculating fluid to assure correct boronometer performance, if dose limitations allow.

• Sump sampling should continue to be used after initiation of an active method to assure the boron concentration control mechanism is working effectively.

• The following must be used for Tincore measurements:

- "Tincore Average Temp" on SPDS alpha page with input from at least (2) incore thermocouples.

- The average of at least 2 incore thermocouples displayed on a chesel recorder (If all inputs are operable the average point may be used).

• The "Delta Boron Limit" as shown on Enclosure 5, includes a 25% factor of safety, and shall be used when the core has been in a saturated condition for greater than five (5) hours.

• Boron precipitation can not occur if adequate SCM exists.

• Stopping an RB Spray Pump could cause RB pressure to increase.

EM-225B Rev. 10 Page 5 of 26

4.0 INSTRUCTIONS 4.1 Emergency Repair Team Maintenance 4.1.1 IF ES MCC 3AB can NOT be energized, THEN coordinate performance of Enclosure 7 in this procedure.

4.2 Boron Precipitation Mitigation Determination 4.2.1 IF adequate SCM exists, THEN Exit this procedure.

4.2.2 WHEN ECCS suction transfer has been completed, THEN calculate Expected RB Sump Concentration (SumpExp) using Enclosure 1 in this procedure.

4.2.3 Request the OSC Chemistry Coordinator to have RB sump boron concentration determined on a 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> interval.

4.2.4 IF at any time RB sump sample results are received, THEN calculate Delta Boron (SumpExp - Measured Sump Boron Concentration).

4.2.5 IF the RB sump can be sampled, THEN perform Enclosure 2 of this procedure.

4.2.6 IF RB sump can NOT be sampled, THEN perform Enclosure 3 of this procedure.

4.3 Boron Precipitation Mitigation Prerequisites 4.3.1 IF LPI crosstie is in progress, THEN prior to directing performance of EOP-14, Enclosure 20, establish HPI piggyback using EM-225E, Guidelines for Long Term Cooling.

4.3.2 IF an HPI pump will be started using EOP-14, Enclosure 20, THEN ensure HPI flow is controlled within the limits of EM-225E.

EM-225B Rev. 10 Page 6 of 26

4.4 Boron Precipitation Mitigation Initiation 4.4.1 IF APS will be directed, THEN consider the following regarding use and effectiveness:

• APS should cause Delta Boron to decrease in < 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after initiation.

• Indications of APS flow:

- Monitor APS line thermocouple indicated on AH-1 003-TIR (DH-61-TE) for early indications of flow. The APS line thermocouple should be DHHE outlet temperature in < 1 minute.

- Continued RB sump sampling, in the longer term, will provide positive verification of successful mitigation.

4.4.2 IF DTS will be directed, THEN consider the following regarding use and effectiveness:

• DTS should cause Delta Boron to decrease in < 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> after initiation.

• Indications of DH drop-line flow:

- Monitor DH drop-line thermocouple indicated on AH-1003-TIR (DH-60-TE) for early indications drop-line flow.

- Continued RB sump sampling, in the longer term, will provide positive verification of successful mitigation.

• Adequate flow in the drop line can be inferred if any of the following exist:

- IF the difference between initial Tincore and average RB temperature is < 40° F, THEN Tincore should be 90% of average RB temperature within 13 minutes.

- IF the difference between initial Tincore and average RB temperature is > 40° F, THEN Tincore should be 90% of average RB temperature within 26 minutes.

EM-225B Rev. 10 Page 7 of 26

4.4.3 WHEN boron precipitation mitigation is required, THEN direct the Control Room to perform the appropriate alignment using EOP-14, Enclosure 20 4.4.4 IF all the following exist:

APS has been directed as the boron precipitation mitigation method A Train LPI is providing APS flow APS was aligned using EOP-14, Enclosure 20

- Tincore plots on Enclosure 4 indicate DHV-5 must be closed for APS effectiveness THEN direct the Control Room to close DHV-5 5.0 FOLLOW-UP ACTIONS

• Continue RB sump monitoring and plotting of Delta Boron.

CONTINGENCY ACTIONS FOR ESTABLISHING AUXILIARY PRESSURIZER SPRAY 1.0 PURPOSE The purpose of this enclosure is to manually initiate APS. The instructions provide a method for manually opening DHV-91 and establishing temporary power for RCV-53 in the event of a power failure to ES MCC 3AB. The re-powering instructions are set up in two sections, dependent upon the condition and failure mode of ES MCC 3AB. The condition of ES MCC 3AB and the associated area dose rates must be considered before performing these instructions.

Section "A": Instructions provide temporary power to ES MCC 3AB-5B in the event of loss of power to ES MCC 3AB, however the control circuitry and indication for RCV-53 will still be utilized at ES MCC 3AB-5B.

Section "B": Instructions provide temporary power and control circuitry for RCV-53, utilizing ES MCC 3B1-8C (Ref. dwg. 206-056). Local control and indication will be at this MCC. ES MCC 3AB is assumed to be inoperable, and no longer intact.
