BASES: (cont'd) t An acceptable method to satisfy the Functional Test requirement for smoke detectors is by pre-testing (actuates at the required setpoint within the required accuracy) the detection instruments, replacing all detection instruments on a o

'~

signaling circuit, and then actuating one detection instrument on the signaling circuit to verify operability of alarm.

The following detectors are not included in the Table 16.9-3 EFA Zones as

" MINIMUM INSTRUMENTS OPERABLE" because they are located in High Rad Areas with minimal combustible loading, or because they are located in non-safety-related areas, As a result, they are also exempt from the TESTING REQUIREMENTS given in this SLC (16.9-6):

Concentrate Batching Tank 1 Room, PP-OO/59 65 A10 404C 577. Evap. Concentrate Holdup Tank Room, 1 NN-PP/59 REASON CODES: 1. High Rad Area 2. Non-Safety-Related Area NOTE 1: For the individual detector designation, see the EFA System Detector Test Procedure (s) (IP/0/A/3350 series).

Excluding the detectors in the above listed rooms from the " MINIMUM INSTRUMENTS OPERABLE" is acceptable for the following reasons:

• All of the above listed detectors are located in rooms that consist of very little to no combustible loading. These rooms contain primarily piping and mechanical equipment such as tanks, demineralizers, or heat exchangers. This type equipment is not significantly prone to fire damage or fire propagation.

. All of the above listed rooms are adjacent to areas that also contain smoke detectors that alarm to the Control Room. Thus, in the unlikely event that a significant fire should occur in one of these rooms, the smoke detectors in the adjacent areas would provide an alarm to the Control Room.

. These rooms are either located in non-safety-related areas, or are located in safety-related areas, but contain components that do ngt perform a safe shutdown function,

)

j

. The areas adjacent to these rooms rely on the same assured train of Post Fire Safe Shutdown. Therefore, a fire in any of these rooms or in an adjacent area would have no adverse impact on Post Fire Safe Shutdown, even in the unlikely event of fire extension to the adjacent areas.

This Selected Licensee Commitment is part of the Catawba Fire Protection Program  ;

and therefore subject to the provisions of Section 2.C. of the Catawba Facility Operating Licenses.
