3.0 PERSONNEL INDOCTRINATION "3.1 Definitions 3.1.1 Off-shore winds - winds originating from NNE to SE sectors (011.20 to 146.30). The most common time for this to occur is midnight.
3.2 Responsibilities 3.2.1 Emergency Coordinator (EC) or designee
- Approves RB purge prior to initiation (Enclosure 6).
- Ensures coordination with off-site agencies prior to initiation of RB purges.
3.2.2 Accident Assessment Team
- Tracks RB conditions and predicts time for RB purge initiation.
- Monitors the effectiveness of purge methods in hydrogen removal.
- Informs the EC of RB conditions and the status of pre-planned releases
- Assign a Purge Release Authorization Form number (Enclosure 6).
3.2.3 Dose Assessment Team
- Monitors meteorological conditions and predicts when off-shore winds should exist.
- Projects off-site doses for proposed RB purges.
3.2.4 Procurement Representative
- Ensures required air compressors are delivered on-site within the required time.
- Ensures support materials (fuel, oil, etc,) are available to support portable compressor operations.
3.2.5 Emergency Repair Team
- Connects temporary air compressors when delivered.
- Installs LR-82-FE, LR-83-FE, LR-82-FI, and LR-83-FI in accordance with MP-815, Installation of Post Accident Hydrogen Purge Monitors.

EM-225A (MC) Rev. 7 Page 4 of 30
3.3 Limits and Precautions 3.3.1 All hydrogen concentration values referenced in this procedure are presented in % by volume as indicated on the hydrogen analyzers.
3.3.2 Maintain RB hydrogen concentration < 3.6% to provide adequate margin below the lower flammability limit of 4.1% for hydrogen in air.
3.3.3 Travel through radiation areas should be as shown in Enclosure 9 unless otherwise directed by the emergency RWP.
3.3.4 Purging should be performed under favorable meteorological conditions (off-shore winds) whenever possible.
3.3.5 RB pressure must be carefully controlled during purge evolutions to prevent ES actuations from high RB pressure.
3.3.6 The purging criteria established by this procedure is not valid during Severe Accidents.
3.3.7 Mission dose calculations credit 10 days of radioactive decay when determining the dose received for performance of local actions. Taking local actions prior to this time may result in excessive radiation exposure.
3.3.8 If a predictable pattern of off-shore winds is identified, consideration should be given to performing a series of intermittent releases during periods when off-shore winds are present.
3.3.9 The AAT is responsible for overall implementation of this procedure. TSC teams responsible for performing the specific actions listed in the enclosures of this procedure are denoted at the end of each step as applicable.

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-225B (MC) Rev. 9 Page 4 of 25
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.

"* Indications of APS flow:
- Monitor APS line thermocouple indicated on AH-1003-TIR (DH-61-TE) for early indications of flow. The APS line thermocouple should be DHHE outlet temperature in < 1 minute.

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 MCCO3AB-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 3B13-8C (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.
