t Open. Item - 19.1.6.4-3 Resolution:
Access and egress is predetermined as indicated in SSAR-Section 9.S.1.0.11 (Amendment 23). The personnel access and egress routes for fire suppression activities are provided consistent with the design of fire barriers, HVAC and smoke control systems. The-access and egress routes and fire doors should be - clearly marked and identified. Once the fire is detected, only the designated access routes and doors should be used.
The magnitude of the differential' pressure which must be maintained across a fire barrier to provide adequate Smoke Control (SSAR Section 9.5.1.0.6) varies with the intensity of the fire and the-room height. For, this reason, it is a COL license information-requirement (Subsection 9.5.13.10)-that the required differential pressure value for each barrier be calculated during the detailed design phase and the HVAC systems be designed to provide the required pressure.
Therefore if the Utility follows the plan as proposed above, smoke removal is not a problem. The Utility should conduct the training and drills for the fire protection tearn on a regular basis.
