TESTING REQUIREMENTS (continued)

TR 16.7-9-20 Verify proper installation of pressurizer insulation. 18 months
TR 16.7-9-21 Verify pressurizer heaters powered from the SSS have a 18 monthscapacity of > 65 kW.
BASES The SSS is designed to mitigate the consequences of certain postulatedfire, security, and station blackout incidents by providing capability tomaintain MODE 3 conditions and by controlling and monitoring vitalsystems from locations external to the main control room. This capabilityis consistent with the requirements of 10 CFR Part 50, Appendix R,NUREG-0800, Section 9.5-1, and Appendix A to Branch TechnicalPosition APSCB 9.5-1.
The TESTING REQUIREMENTS ensure that the SSS systems andcomponents are capable of performing their intended functions. Therequired level in the SSS diesel generator fuel storage tank ensuressufficient fuel for 72 hours uninterrupted operation. It is assumed that,within 72 hours, either offsite power can be restored or additional fuel canbe added to the storage tank.
Although the standby makeup pump is not nuclear safety related and wasnot designed according to ASME Code requirements, it is tested quarterlyto ensure its FUNCTIONALITY. The TESTING REQUIREMENTconcerning the standby makeup pump water supply ensures that anadequate water volume is available to supply the pump continuously for72 hours.
Total accumulative LEAKAGE is calculated in the NC System LeakageCalculation procedure as identified + unidentified + seal leakoff(References 2 and 3). The REMEDIAL ACTION limit of 20 gpm totalaccumulative LEAKAGE provides additional margin to allow forinstrument inaccuracy, and for the predicted increase in seal leakoff ratedue to heatup of the reactor coolant pump seal injection water supplytemperature following the SSS event (due to spent fuel pool heatup).Following the increase in seal injection temperature, the standby makeuppump flow of 26 gpm is sufficient to provide in excess of this totalaccumulative LEAKAGE, thereby assuring that reactor coolant systeminventory is maintained at MODE 3 conditions. The supporting evaluationis provided in CNC-1223.04-00-0072 (Ref. 4).
A visual inspection of the diesel starting 24-volt batteries, cell plates, andbattery racks provides an indication of physical damage or abnormaldeterioration that could potentially degrade battery performance. Since
Catawba Units 1 and 2 16.7-9-4 Revision 7
SSS16.7-9
BASES (continued)
the battery cell jars are not transparent, a direct visual inspection of thecell plates cannot be performed. Instead, the cell plates are inspected forphysical damage and abnormal deterioration by: 1) visually inspectingthe jar sides of each cell for excessive bowing and/or deformation, and 2)visually inspecting the electrolyte of each cell for abnormal appearance.
Verifying individual cell voltage while on float charge for the SSS dieselstarting 24-Volt batteries ensures that each cell is capable of supportingits intended function. Float charge is the condition in which the charger issupplying the continuous charge required to overcome the internal lossesof a battery (or battery cell) and maintain the battery (or battery cell) in afully charged state. The battery cell voltage limit of 1.36 volts isconsistent with the nominal design voltage of the battery and is based onthe manufacturer's recommended minimum float charge voltage for afully charged cell with adequate capacity. The battery is designed andsized with a capacity margin sufficient to allow up to one cell per batterybank to be fully degraded with a voltage < 1.36 volts assuming that nocells are jumpered out. The battery sizing calculations account for onedegraded cell per battery bank by assuming the degraded cells undergoa worst case polarity reversal during SSS diesel starting.
Verification of proper installation of pressurizer insulation ensures thatpressurizer heat losses during an SSS event do not exceed the capacityof the pressurizer heaters powered from the SSS.
Testing of the pressurizer heater capacity ensures the full capacity of theheaters is available to maintain a steam bubble in the pressurizer duringan SSS event.

TR 16.7-9-20 Verify proper installation of pressurizer insulation. 18 months
TR 16.7-9-21 Verify pressurizer heaters powered from the SSS have a 18 monthscapacity of > 65 kW.
BASES The SSS is designed to mitigate the consequences of certain postulatedfire, security, and station blackout incidents by providing capability tomaintain MODE 3 conditions and by controlling and monitoring vitalsystems from locations external to the main control room. This capabilityis consistent with the requirements of 10 CFR Part 50, Appendix R,NUREG-0800, Section 9.5-1, and Appendix A to Branch TechnicalPosition APSCB 9.5-1.
The TESTING REQUIREMENTS ensure that the SSS systems andcomponents are capable of performing their intended functions. Therequired level in the SSS diesel generator fuel storage tank ensuressufficient fuel for 72 hours uninterrupted operation. It is assumed that,within 72 hours, either offsite power can be restored or additional fuel canbe added to the storage tank.
Although the standby makeup pump is not nuclear safety related and wasnot designed according to ASME Code requirements, it is tested quarterlyto ensure its FUNCTIONALITY. The TESTING REQUIREMENTconcerning the standby makeup pump water supply ensures that anadequate water volume is available to supply the pump continuously for72 hours.
Total accumulative LEAKAGE is calculated in the NC System LeakageCalculation procedure as identified + unidentified + seal leakoff(References 2 and 3). The REMEDIAL ACTION limit of 20 gpm totalaccumulative LEAKAGE provides additional margin to allow forinstrument inaccuracy, and for the predicted increase in seal leakoff ratedue to heatup of the reactor coolant pump seal injection water supplytemperature following the SSS event (due to spent fuel pool heatup).Following the increase in seal injection temperature, the standby makeuppump flow of 26 gpm is sufficient to provide in excess of this totalaccumulative LEAKAGE, thereby assuring that reactor coolant systeminventory is maintained at MODE 3 conditions. The supporting evaluationis provided in CNC-1223.04-00-0072 (Ref. 4).
A visual inspection of the diesel starting 24-volt batteries, cell plates, andbattery racks provides an indication of physical damage or abnormaldeterioration that could potentially degrade battery performance. Since
Catawba Units 1 and 2 16.7-9-4 Revision 7
SSS16.7-9
BASES (continued)
the battery cell jars are not transparent, a direct visual inspection of thecell plates cannot be performed. Instead, the cell plates are inspected forphysical damage and abnormal deterioration by: 1) visually inspectingthe jar sides of each cell for excessive bowing and/or deformation, and 2)visually inspecting the electrolyte of each cell for abnormal appearance.
Verifying individual cell voltage while on float charge for the SSS dieselstarting 24-Volt batteries ensures that each cell is capable of supportingits intended function. Float charge is the condition in which the charger issupplying the continuous charge required to overcome the internal lossesof a battery (or battery cell) and maintain the battery (or battery cell) in afully charged state. The battery cell voltage limit of 1.36 volts isconsistent with the nominal design voltage of the battery and is based onthe manufacturer's recommended minimum float charge voltage for afully charged cell with adequate capacity. The battery is designed andsized with a capacity margin sufficient to allow up to one cell per batterybank to be fully degraded with a voltage < 1.36 volts assuming that nocells are jumpered out. The battery sizing calculations account for onedegraded cell per battery bank by assuming the degraded cells undergoa worst case polarity reversal during SSS diesel starting.
Verification of proper installation of pressurizer insulation ensures thatpressurizer heat losses during an SSS event do not exceed the capacityof the pressurizer heaters powered from the SSS.
Testing of the pressurizer heater capacity ensures the full capacity of theheaters is available to maintain a steam bubble in the pressurizer duringan SSS event.

Instead, the cell plates are inspected forphysical damage and abnormal deterioration by: 1) visually inspectingthe jar sides of each cell for excessive bowing and/or deformation, and 2)visually inspecting the electrolyte of each cell for abnormal appearance.
Verifying individual cell voltage while on float charge for the SSS dieselstarting 24-Volt batteries ensures that each cell is capable of supportingits intended function. Float charge is the condition in which the charger issupplying the continuous charge required to overcome the internal lossesof a battery (or battery cell) and maintain the battery (or battery cell) in afully charged state. The battery cell voltage limit of 1.36 volts isconsistent with the nominal design voltage of the battery and is based onthe manufacturer's recommended minimum float charge voltage for afully charged cell with adequate capacity. The battery is designed andsized with a capacity margin sufficient to allow up to one cell per batterybank to be fully degraded with a voltage < 1.36 volts assuming that nocells are jumpered out. The battery sizing calculations account for onedegraded cell per battery bank by assuming the degraded cells undergoa worst case polarity reversal during SSS diesel starting.
Verification of proper installation of pressurizer insulation ensures thatpressurizer heat losses during an SSS event do not exceed the capacityof the pressurizer heaters powered from the SSS.
Testing of the pressurizer heater capacity ensures the full capacity of theheaters is available to maintain a steam bubble in the pressurizer duringan SSS event.

TR 16.7-9-21 Verify pressurizer heaters powered from the SSS have a 18 monthscapacity of > 65 kW.
BASES The SSS is designed to mitigate the consequences of certain postulatedfire, security, and station blackout incidents by providing capability tomaintain MODE 3 conditions and by controlling and monitoring vitalsystems from locations external to the main control room. This capabilityis consistent with the requirements of 10 CFR Part 50, Appendix R,NUREG-0800, Section 9.5-1, and Appendix A to Branch TechnicalPosition APSCB 9.5-1.
The TESTING REQUIREMENTS ensure that the SSS systems andcomponents are capable of performing their intended functions. Therequired level in the SSS diesel generator fuel storage tank ensuressufficient fuel for 72 hours uninterrupted operation. It is assumed that,within 72 hours, either offsite power can be restored or additional fuel canbe added to the storage tank.
Although the standby makeup pump is not nuclear safety related and wasnot designed according to ASME Code requirements, it is tested quarterlyto ensure its FUNCTIONALITY. The TESTING REQUIREMENTconcerning the standby makeup pump water supply ensures that anadequate water volume is available to supply the pump continuously for72 hours.
Total accumulative LEAKAGE is calculated in the NC System LeakageCalculation procedure as identified + unidentified + seal leakoff(References 2 and 3). The REMEDIAL ACTION limit of 20 gpm totalaccumulative LEAKAGE provides additional margin to allow forinstrument inaccuracy, and for the predicted increase in seal leakoff ratedue to heatup of the reactor coolant pump seal injection water supplytemperature following the SSS event (due to spent fuel pool heatup).Following the increase in seal injection temperature, the standby makeuppump flow of 26 gpm is sufficient to provide in excess of this totalaccumulative LEAKAGE, thereby assuring that reactor coolant systeminventory is maintained at MODE 3 conditions. The supporting evaluationis provided in CNC-1223.04-00-0072 (Ref. 4).
A visual inspection of the diesel starting 24-volt batteries, cell plates, andbattery racks provides an indication of physical damage or abnormaldeterioration that could potentially degrade battery performance. Since

TR 16.7-9-20 Verify proper installation of pressurizer insulation. 18 months
TR 16.7-9-21 Verify pressurizer heaters powered from the SSS have a 18 monthscapacity of > 65 kW.
BASES The SSS is designed to mitigate the consequences of certain postulatedfire, security, and station blackout incidents by providing capability tomaintain MODE 3 conditions and by controlling and monitoring vitalsystems from locations external to the main control room. This capabilityis consistent with the requirements of 10 CFR Part 50, Appendix R,NUREG-0800, Section 9.5-1, and Appendix A to Branch TechnicalPosition APSCB 9.5-1.
The TESTING REQUIREMENTS ensure that the SSS systems andcomponents are capable of performing their intended functions. Therequired level in the SSS diesel generator fuel storage tank ensuressufficient fuel for 72 hours uninterrupted operation. It is assumed that,within 72 hours, either offsite power can be restored or additional fuel canbe added to the storage tank.
Although the standby makeup pump is not nuclear safety related and wasnot designed according to ASME Code requirements, it is tested quarterlyto ensure its FUNCTIONALITY. The TESTING REQUIREMENTconcerning the standby makeup pump water supply ensures that anadequate water volume is available to supply the pump continuously for72 hours.
Total accumulative LEAKAGE is calculated in the NC System LeakageCalculation procedure as identified + unidentified + seal leakoff(References 2 and 3). The REMEDIAL ACTION limit of 20 gpm totalaccumulative LEAKAGE provides additional margin to allow forinstrument inaccuracy, and for the predicted increase in seal leakoff ratedue to heatup of the reactor coolant pump seal injection water supplytemperature following the SSS event (due to spent fuel pool heatup).Following the increase in seal injection temperature, the standby makeuppump flow of 26 gpm is sufficient to provide in excess of this totalaccumulative LEAKAGE, thereby assuring that reactor coolant systeminventory is maintained at MODE 3 conditions. The supporting evaluationis provided in CNC-1223.04-00-0072 (Ref. 4).
A visual inspection of the diesel starting 24-volt batteries, cell plates, andbattery racks provides an indication of physical damage or abnormaldeterioration that could potentially degrade battery performance. Since
Catawba Units 1 and 2 16.7-9-4 Revision 7
SSS16.7-9
BASES (continued)
the battery cell jars are not transparent, a direct visual inspection of thecell plates cannot be performed. Instead, the cell plates are inspected forphysical damage and abnormal deterioration by: 1) visually inspectingthe jar sides of each cell for excessive bowing and/or deformation, and 2)visually inspecting the electrolyte of each cell for abnormal appearance.
Verifying individual cell voltage while on float charge for the SSS dieselstarting 24-Volt batteries ensures that each cell is capable of supportingits intended function. Float charge is the condition in which the charger issupplying the continuous charge required to overcome the internal lossesof a battery (or battery cell) and maintain the battery (or battery cell) in afully charged state. The battery cell voltage limit of 1.36 volts isconsistent with the nominal design voltage of the battery and is based onthe manufacturer's recommended minimum float charge voltage for afully charged cell with adequate capacity. The battery is designed andsized with a capacity margin sufficient to allow up to one cell per batterybank to be fully degraded with a voltage < 1.36 volts assuming that nocells are jumpered out. The battery sizing calculations account for onedegraded cell per battery bank by assuming the degraded cells undergoa worst case polarity reversal during SSS diesel starting.
Verification of proper installation of pressurizer insulation ensures thatpressurizer heat losses during an SSS event do not exceed the capacityof the pressurizer heaters powered from the SSS.
Testing of the pressurizer heater capacity ensures the full capacity of theheaters is available to maintain a steam bubble in the pressurizer duringan SSS event.

TESTING REQUIREMENTS (continued)
TEST FREQUENCY
TR 16.7-9-20 Verify proper installation of pressurizer insulation. 18 months
TR 16.7-9-21 Verify pressurizer heaters powered from the SSS have a 18 monthscapacity of > 65 kW.
BASES The SSS is designed to mitigate the consequences of certain postulatedfire, security, and station blackout incidents by providing capability tomaintain MODE 3 conditions and by controlling and monitoring vitalsystems from locations external to the main control room. This capabilityis consistent with the requirements of 10 CFR Part 50, Appendix R,NUREG-0800, Section 9.5-1, and Appendix A to Branch TechnicalPosition APSCB 9.5-1.
The TESTING REQUIREMENTS ensure that the SSS systems andcomponents are capable of performing their intended functions. Therequired level in the SSS diesel generator fuel storage tank ensuressufficient fuel for 72 hours uninterrupted operation. It is assumed that,within 72 hours, either offsite power can be restored or additional fuel canbe added to the storage tank.
Although the standby makeup pump is not nuclear safety related and wasnot designed according to ASME Code requirements, it is tested quarterlyto ensure its FUNCTIONALITY.. The TESTING REQUIREMENTconcerning the standby makeup pump water supply ensures that anadequate water volume is available to supply the pump continuously for72 hours.
Total accumulative LEAKAGE is calculated in the NC System LeakageCalculation procedure as identified + unidentified + seal leakoff(References 2 and 3). The REMEDIAL ACTION limit of 20 gpm totalaccumulative LEAKAGE provides additional margin to allow forinstrument inaccuracy, and for the predicted increase in seal leakoff ratedue to heatup of the reactor coolant pump seal injection water supplytemperature following the SSS event (due to spent fuel pool heatup).Following the increase in seal injection temperature, the standby makeuppump flow of 26 gpm is sufficient to provide in excess of this totalaccumulative LEAKAGE, thereby assuring that reactor coolant systeminventory is maintained at MODE 3 conditions. The supporting evaluationis provided in CNC-1223.04-00-0072 (Ref. 4).
A visual inspection of the diesel starting 24-volt batteries, cell plates, andbattery racks provides an indication of physical damage or abnormaldeterioration that could potentially degrade battery performance. Since
Catawba Units 1 and 2 16.7-9-4 Revision 7
SSS16.7-9
BASES (continued)
the battery cell jars are not transparent, a direct visual inspection of thecell plates cannot be performed. Instead, the cell plates are inspected forphysical damage and abnormal deterioration by: 1) visually inspectingthe jar sides of each cell for excessive bowing and/or deformation, and 2)visually inspecting the electrolyte of each cell for abnormal appearance.
Verifying individual cell voltage while on float charge for the SSS dieselstarting 24-Volt batteries ensures that each cell is capable of supportingits intended function. Float charge is the condition in which the charger issupplying the continuous charge required to overcome the internal lossesof a battery (or battery cell) and maintain the battery (or battery cell) in afully charged state. The battery cell voltage limit of 1.36 volts isconsistent with the nominal design voltage of the battery and is based onthe manufacturer's recommended minimum float charge voltage for afully charged cell with adequate capacity. The battery is designed andsized with a capacity margin sufficient to allow up to one cell per batterybank to be fully degraded with a voltage < 1.36 volts assuming that nocells are jumpered out. The battery sizing calculations account for onedegraded cell per battery bank by assuming the degraded cells undergoa worst case polarity reversal during SSS diesel starting.
Verification of proper installation of pressurizer insulation ensures thatpressurizer heat losses during an SSS event do not exceed the capacityof the pressurizer heaters powered from the SSS.
Testing of the pressurizer heater capacity ensures the full capacity of theheaters is available to maintain a steam bubble in the pressurizer duringan SSS event.

TR 16.7-9-20 Verify proper installation of pressurizer insulation. 18 months
TR 16.7-9-21 Verify pressurizer heaters powered from the SSS have a 18 monthscapacity of > 65 kW.
BASES The SSS is designed to mitigate the consequences of certain postulatedfire, security, and station blackout incidents by providing capability tomaintain MODE 3 conditions and by controlling and monitoring vitalsystems from locations external to the main control room. This capabilityis consistent with the requirements of 10 CFR Part 50, Appendix R,NUREG-0800, Section 9.5-1, and Appendix A to Branch TechnicalPosition APSCB 9.5-1.
The TESTING REQUIREMENTS ensure that the SSS systems andcomponents are capable of performing their intended functions. Therequired level in the SSS diesel generator fuel storage tank ensuressufficient fuel for 72 hours uninterrupted operation. It is assumed that,within 72 hours, either offsite power can be restored or additional fuel canbe added to the storage tank.
Although the standby makeup pump is not nuclear safety related and wasnot designed according to ASME Code requirements, it is tested quarterlyto ensure its FUNCTIONALITY. The TESTING REQUIREMENTconcerning the standby makeup pump water supply ensures that anadequate water volume is available to supply the pump continuously for72 hours.
Total accumulative LEAKAGE is calculated in the NC System LeakageCalculation procedure as identified + unidentified + seal leakoff(References 2 and 3). The REMEDIAL ACTION limit of 20 gpm totalaccumulative LEAKAGE provides additional margin to allow forinstrument inaccuracy, and for the predicted increase in seal leakoff ratedue to heatup of the reactor coolant pump seal injection water supplytemperature following the SSS event (due to spent fuel pool heatup).Following the increase in seal injection temperature, the standby makeuppump flow of 26 gpm is sufficient to provide in excess of this totalaccumulative LEAKAGE, thereby assuring that reactor coolant systeminventory is maintained at MODE 3 conditions. The supporting evaluationis provided in CNC-1223.04-00-0072 (Ref. 4).
A visual inspection of the diesel starting 24-volt batteries, cell plates, andbattery racks provides an indication of physical damage or abnormaldeterioration that could potentially degrade battery performance. Since
Catawba Units 1 and 2 16.7-9-4 Revision 7

BASES (continued)
the battery cell jars are not transparent, a direct visual inspection of thecell plates cannot be performed. Instead, the cell plates are inspected forphysical damage and abnormal deterioration by: 1) visually inspectingthe jar sides of each cell for excessive bowing and/or deformation, and 2)visually inspecting the electrolyte of each cell for abnormal appearance.
Verifying individual cell voltage while on float charge for the SSS dieselstarting 24-Volt batteries ensures that each cell is capable of supportingits intended function. Float charge is the condition in which the, charger issupplying the continuous charge required to overcome the internal lossesof a battery (or battery cell) and maintain the battery (or battery cell) in afully charged state. The battery cell voltage limit of 1.36 volts isconsistent with the nominal design voltage of the battery and is based onthe manufacturer's recommended minimum float charge voltage for afully charged cell with adequate capacity. The battery is designed andsized with a capacity margin sufficient to allow up to one cell per batterybank to be fully degraded with a voltage < 1.36 volts assuming that nocells are jumpered out. The battery sizing calculations account for onedegraded cell per battery bank by assuming the degraded cells undergoa worst case polarity reversal during SSS diesel starting.
Verification of proper installation of pressurizer insulation ensures thatpressurizer heat losses during an SSS event do not exceed the capacityof the pressurizer heaters powered from the SSS.
Testing of the pressurizer heater capacity ensures the full capacity of theheaters is available to maintain a steam bubble in the pressurizer duringan SSS event.

TESTING REQUIREMENTS (continued)
TEST FREQUENCY
TR 16.7-9-20 Verify proper installation of pressurizer insulation. 18 months
TR 16.7-9-21 Verify pressurizer heaters powered from the SSS have a 18 monthscapacity of > 65 kW.
BASES The SSS is designed to mitigate the consequences of certain postulatedfire, security, and station blackout incidents by providing capability tomaintain MODE 3 conditions and by controlling and monitoring vitalsystems from locations external to the main control room. This capabilityis consistent with the requirements of 10 CFR Part 50, Appendix R,NUREG-0800, Section 9.5-1, and Appendix A to Branch TechnicalPosition APSCB 9.5-1.
The TESTING REQUIREMENTS ensure that the SSS systems andcomponents are capable of performing their intended functions. Therequired level in the SSS diesel generator fuel storage tank ensuressufficient fuel for 72 hours uninterrupted operation. It is assumed that,within 72 hours, either offsite power can be restored or additional fuel canbe added to the storage tank.
Although the standby makeup pump is not nuclear safety related and wasnot designed according to ASME Code requirements, it is tested quarterlyto ensure its FUNCTIONALITY. The TESTING REQUIREMENTconcerning the standby makeup pump water supply ensures that anadequate water volume is available to supply the pump continuously for72 hours.
Total accumulative LEAKAGE is calculated in the NC System LeakageCalculation procedure as identified + unidentified + seal leakoff(References 2 and 3). The REMEDIAL ACTION limit of 20 gpm totalaccumulative LEAKAGE provides additional margin to allow forinstrument inaccuracy, and for the predicted increase in seal leakoff ratedue to heatup of the reactor coolant pump seal injection water supplytemperature following the SSS event (due to spent fuel pool heatup).Following the increase in seal injection temperature, the standby makeuppump flow of 26 gpm is sufficient to provide in excess of this totalaccumulative LEAKAGE, thereby assuring that reactor coolant systeminventory is maintained at MODE 3 conditions. The supporting evaluationis provided in CNC-1223.04-00-0072 (Ref. 4).
A visual inspection of the diesel starting 24-volt batteries, cell plates, andbattery racks provides an indication of physical damage or abnormaldeterioration that could potentially degrade battery performance. Since

BASES (continued)
the battery cell jars are not transparent, a direct visual inspection of thecell plates cannot be performed. Instead, the cell plates are inspected forphysical damage and abnormal deterioration by: 1) visually inspectingthe jar sides of each cell for excessive bowing and/or deformation, and 2)visually inspecting the electrolyte of each cell for abnormal appearance.
Verifying individual cell voltage while on float charge for the SSS dieselstarting 24-Volt batteries ensures that each cell is capable of supportingits intended function. Float charge is the condition in which the charger issupplying the continuous charge required to overcome the internal lossesof a battery (or battery cell) and maintain the battery (or battery cell) in afully charged state. The battery cell voltage limit of 1.36 volts isconsistent with the nominal design voltage of the battery and is based onthe manufacturer's recommended minimum float charge voltage for afully charged cell with adequate capacity. The battery is designed andsized with a capacity margin sufficient to allow up to one cell per batterybank to be fully degraded with a voltage < 1.36 volts assuming that nocells are jumpered out. The battery sizing calculations account for onedegraded cell per battery bank by assuming the degraded cells undergoa worst case polarity reversal during SSS diesel starting.
Verification of proper installation of pressurizer insulation ensures thatpressurizer heat losses during an SSS event do not exceed the capacityof the pressurizer heaters powered from the SSS.
Testing of the pressurizer heater capacity ensures the full capacity of theheaters is available to maintain a steam bubble in the pressurizer duringan SSS event.
