cpl &2/,A2002/005 Page 2 of 7 Post Accident Caustic Injection into the Low Pressure Injection System NOTE:
- 1. This entire procedure supports an AP or EOP action. The procedure will require AP/EOP validation per NSD 705.
- 2. A control copy of this procedure shall be routed to the Emergency Preparedness Team within 3 working days after any approved changes.
- 1. Purpose 1.1 This procedure is to provide instruction for determining the amount and method of caustic addition into the LPI System during a LOCA.
1.2 Principle Caustic is injected into the LPI System during a LOCA to neutralize tfie borated water used in the Reactor Building Emergency Spray System to pH 7.0 - 8.0.
The neutralization will inhibit the generation of hydrogen gas and promote a higher partition factor for iodine.
- 2. Limits and Precautions 0l 2.1 The following safety equipment shall be worn when connecting/disconnecting caustic tote bins:
2.1.1 Chemical goggles 2.1.2 Face shield 2.1.3 Corrosive resistant suit, neoprene or chemrel 2.1.4 Corrosive resistant boots, neoprene or PVC 2.1.5 Corrosive resistant gloves, neoprene or PVC 0I 2.2 Chemical hazards shall be known prior to use. For additional information refer to the MSDS sheets.
0I 2.3 Under accident conditions, valve alignments shall NOT be made and injection shall NOT begin without prior authorization from the Operations Emergency Coordinator OR the Technical Support Center (TSC)/Operational Support Center (OSC)!
cP/1 &2/A/2002/005 Page 3 of 7 NOTE:
An initial caustic add of 15 inches will neutralize an RCS inventory of 80,000 gallons with a boron concentration of 1800 ppm. This is a conservative initial add to allow immediate response to a large break LOCA.
0I 2.4 An initial caustic add of 15 inches can be made without performing CSM 5.2, Enclosure 6.3 (Caustic Addition Calculations).
0] 2.5 In the event of a caustic spill, call 4911.
0i 2.6 ITS 5.4.1.a and SLC 16.13.7 require that pH be measured AND that the addition of caustic Sto Reactor Coolant commence within 30 minutes AFTER switchover to Recirculation Mode of Core Cooling to adjust the pH to a range of 7.0 to 8.0 WITHIN 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
During recirculation mode, long-term core cooling is provided by injection of water from the Reactor Building Emergency Sump to the core by the Low Pressure Injection (LPI) pumps (1 LP-19 & 20 or 2 LP-19 & 20 are open). Switchover to recirculation mode is accomplished with minimal level in the BWST.
0l 2.7 Safety and caustic addition equipment is stored in the brown storage container located in the Auxiliary Building, Unit 1 & 2 Chemical Addition Area.
0I 2.8 Keys to the brown storage container are stored with the caustic addition procedures in the OSC Chemistry Emergency Procedure Files and in the fireproof cabinet located in the Primary Chemistry lab office. All personnel in Primary Chemistry and Radwaste have also been issued individual keys.
0l 2.9 Power to the caustic addition pump is provided through 1XL located near the LPI hatch area.
For power supply diagram, see Enclosure 5.6.

(LOCA) 1.2 Principle Caustic is injected into the LPI System during a LOCA to neutralize ttie borated water used in the Reactor Building Emergency Spray System to pH 7.0 - 8.0.
The neutralization will inhibit the generation of hydrogen gas and promote a higher partition factor for iodine.
- 2. Limits and Precautions 0l 2.1 The following safety equipment shall be worn when connecting/disconnecting caustic tote bins:
2.1.1 Chemical goggles 2.1.2 Face shield 2.1.3 Corrosive resistant suit, neoprene or chemrel 2.1.4 Corrosive resistant boots, neoprene or PVC 2.1.5 Corrosive resistant gloves, neoprene or PVC 0l 2.2 Chemical hazards shall be known prior to use. For additional information, refer to the MSDS sheets.
El 2.3 Under accident conditions, valve alignments shall NOT be made and injection shall NOT begin without prior authorization from the Operations Emergency Coordinator OR the Technical Support Center (TSC) / Operational Support Center (OSC)!
cP/3/A/2002/005 Page 3 of 7 NOTE:
An initial caustic add of 15 inches will neutralize an RCS inventory of 80,000 gallons with a boron concentration of 1800 ppm. This is a conservative initial add to allow immediate response to a large break LOCA.
El 2.4 An initial caustic add of 15 inches can be made without performing CSM 5.2,.3 (Caustic Addition Calculations).
0l 2.5 In the event of caustic spill, call 4911.
o 2.6 ITS 5.4.l.a and SLC 16.13.7 require that pH be measured AND that the addition of caustic to Reactor Coolant commence within 30 minutes AFTER switchover to recirculation mode of core cooling to adjust pH to a range of 7.0 to 8.0 WITHIN 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
During recirculation mode, long-term core cooling is provided by injectioii of water from the Reactor Building Emergency Sump to the core by the Low Piessure Injection (LPI) pumps (3 LP-19 and 3 LP-20 are open). Switchover to recirculation mode is accomplished with minimal level in the BWST.
El 2.7 Safety and caustic addition equipment is stored in the brown storage container located in the Auxiliary Building, Unit 1 & 2 Chemical Addition Area. The following equipment should be retrieved for Caustic Addition:
Chemical Goggles Tape Measure Face Shield Marking Pen (to mark level on Tote Bin)
Corrosive resistant suit Bung Wrench Corrosive resistant gloves Leather Gloves El 2.8 Keys to the brown storage container are stored with the caustic addition procedure in the OSC Chemistry Emergency Procedure Files and in the fireproof cabinet located in the Primary Chemistry lab office. All personnel in Primary Chemistry and Radwaste have also been issued individual keys.
El 2.9 Power to the caustic addition pump is provided through 3XL located near the LPI Hatch Area. For power supply diagram, see Enclosure 5.4.
