Catawba Units 1 and 2 16.9-1-3 Revision 7 Fire Suppression Water System 16.9-1 TESTING REQUIREMENTS (continued)

TEST FREQUENCY TR 16.9-1-7 Cycle each valve in the flow path which is not testable 18 months during plant operation through at least one complete cycle of full travel.TR 16.9-1-8 Perform a system flow test in accordance with Chapter 8, 3 years Section 16 of the National Fire Protection Association Fire Protection Handbook, 15th Edition.BASES The FUNCTIONALITY of the Fire Suppression Systems ensures that adequate fire suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety related equipment is located. The Fire Suppression System consists of the water supply/distribution system, sprinkler systems, fire hose stations, fire hydrants, and CO 2 systems. The collective capability of the Fire Suppression Systems is adequate to minimize potential damage to safety related equipment and is a major element in the facility Fire Protection Program.The intent of COMMITMENT

b. is to ensure a FUNCTIONAL flow path from the water source (in this case Lake Wylie), through FUNCTIONAL pumps as required in COMMITMENT a., and through the main header distribution piping -up to and including the branch lines for each sprinkler system, hose standpipe, or fire hydrant required to be FUNCTIONAL per SLCs 16.9-2, 16.9-4, and 16.9-23. When a sectionalizing valve or an isolation valve becomes non-functional, then the fire suppression features (sprinkler system, hose standpipe, or fire hydrant) affected must be evaluated and the applicable SLCs entered (16.9-2, 16.9-4, and 16.9-23).Condition C of this SLC would only apply if a non-functional sectionalizing valve(s) or isolation valve(s) rendered the entire main distribution piping non-functional.

The intent of TR 16.9-1-4 and TR 16.9-1-7 is to ensure the sectionalizing valve (main header valve used to isolate sections of the header) or isolation valve (branch line valve used to isolate specific fire suppression features (sprinkler system, hose standpipe, or fire hydrant))

is operating properly and can be used to achieve isolation when called upon. If a sectionalizing or isolation valve cannot be cycled but is in the correct position ensuring a FUNCTIONAL flow path (fully open) as required by COMMITMENT b., then the associated feature (sprinkler system, hose standpipe, or fire hydrant) can be considered FUNCTIONAL.

If a sectionalizing or isolation valve cannot be cycled and is in the incorrect Catawba Units 1 and 2 16.9-1-4 Revision 7 Fire Suppression Water System 16.9-1 BASES (continued) position, or its position cannot be determined, thereby not ensuring a FUNCTIONAL flow path (not fully open) as required by COMMITMENT b., then the affected fire suppression feature (sprinkler system, hose standpipe, or fire hydrant) must be evaluated and the applicable SLCs entered (16.9-2, 16.9-4, and 16.9-23).

If a sectionalizing valve in a loop header (i.e., flow path from two directions) cannot be cycled and it cannot be verified as fully open, then administrative controls may need to be implemented to ensure the available flow path is not isolated.The ability to demonstrate that the valves in the RF/RY flow path can be cycled is critical to maintaining the system properly.

The containment isolation valves (RF389B and RF447B) and the annulus sprinkler system isolation valve (RF457B) are required to be cycled or stroked in accordance with the Catawba Inservice Testing Program. Therefore, credit can be taken for cycling these valves under the IWV program, and they do not need to be cycled annually to meet the SLC criteria.The proper positioning of RF/RY valves is critical to delivering fire suppression water at the fire source as quickly as possible.

The option of increasing or decreasing the frequency of valve position verification allows the ability to optimize plant operational resources.

Should an adverse trend develop with RF/RY valve positions, the frequency of verification shall be increased.

Similarly, if the RF/RY valve position trends are positive, the frequency of verification could be decreased.

Through programmed trending of RF/RY as found valve positions, the RF/RY System will be maintained at predetermined reliability standards.

The Fire Protection Engineer is responsible for trending and determining verification frequencies based on the following:

Initially the frequency shall be monthly.Annually review the results of the completed valve position verification procedures." If the results demonstrate that the valves are found in the correct position at least 99% of the time, the frequency of conducting the valve position verification may be decreased from monthly to quarterly or quarterly to semiannually or semiannually to annually as applicable.

The frequency shall not be extended beyond annually (plus grace period)." If the results demonstrate that the valves are not found in the correct position at least 99% of the time, the frequency of conducting the valve position verification shall be increased from annually to semiannually or semiannually to quarterly or quarterly to monthly as applicable.

The valve position verification need not be conducted more often than monthly.Catawba Units 1 and 2 16.9-1-5 Revision 7 Fire Suppression Water System 16.9-1 BASES (continued)

In the event that portions of the Fire Suppression Systems are non-functional, alternate backup fire fighting equipment is required to be made available in the affected areas until the non-functional equipment is restored to service. When the non-functional fire fighting equipment is intended for use as a backup means of fire suppression, a longer period of time is allowed to provide an alternate means of fire fighting than if the non-functional equipment is the primary means of fire suppression.

In the event the Fire Suppression Water System becomes non-functional, immediate corrective measures must be taken since this system provides the major fire suppression capability of the plant.Since the requirement for fire suppression pump automatic starting functions is intended to provide a high level of system standby readiness, loss of a primary pressure switch renders its associated main fire pump non-functional.

If the primary pressure switch for one of the two required pumps is non-functional, its associated pump is non-functional if not placed in continuous operation and Condition A applies. If both primary pressure switches for the required pumps are non-functional, it is acceptable to place at least one of the two required pumps in continuous operation and restore FUNCTIONALITY within 7 days, which is essentially meeting the requirements of Condition A (one of the two required pumps non-functional).

If a sectionalizing or isolation valve cannot be cycled and is in the incorrect position, or its position cannot be determined, thereby not ensuring a FUNCTIONAL flow path (not fully open) as required by COMMITMENT 16.9-1 b., then the affected fire suppression feature (sprinkler system, hose standpipe, or fire hydrant) must be evaluated and the applicable SLCs entered (16.9-2, 16.9-4, and 16.9-23).

When a required Sprinkler System is non-functional, the REMEDIAL ACTION is to establish an appropriate fire watch, and verify or establish backup fire suppression in the affected area. The REMEDIAL ACTION allows for the use of either a nearby fire hose station or a fire extinguisher as an acceptable means of backup fire suppression.

Typically, the preferred choice is to credit a nearby fire hose station as the backup means of suppression.

In most cases, nearby fire hose stations exist in the areas affected by a non-functional Sprinkler System. However, in some instances there are areas that do not contain any fire hose stations, such as the Annulus. In the case of the Annulus Sprinkler System, credit is taken for the portable fire extinguishers near the upper and lower Annulus access doors as the backup means of suppression.

The Fire Suppression System consists of the water supply/distribution system, sprinkler systems, fire hose stations, fire hydrants, and CO 2 systems. The collective capability of the Fire Suppression Systems is adequate to minimize potential damage to safety related equipment and is a major element in the facility Fire Protection Program.The intent of TR 16.9-23-4 is to ensure the sectionalizing valve (main header valve used to isolate sections of the header) or isolation valve (branch line valve used to isolate specific fire suppression features (sprinkler system, hose standpipe, or fire hydrant))

is operating properly and can be used to achieve isolation when called upon. If a sectionalizing or isolation valve cannot be cycled but is in the correct position ensuring a FUNCTIONAL flow path (fully open) as required by COMMITMENT 16.9-1 b., then the associated feature (sprinkler system, hose standpipe, or fire hydrant) can be considered FUNCTIONAL.

If a sectionalizing or isolation valve cannot be cycled and is in the incorrect position, or its position cannot be determined, thereby not ensuring a FUNCTIONAL flow path (not fully open) as required by COMMITMENT 16.9-1 b., then the affected fire suppression feature (sprinkler system, Catawba Units 1 and 2 16.9-23-2 Revision 4 BASES (continued) hose standpipe, or fire hydrant) must be evaluated and the applicable SLCs entered (16.9-2, 16.9-4, and 16.9-23).
