- 9. 5 OTHER AUXILIARY SYSTEMS 9.5.1 FIRE PROTECTION SYSTEM 9.5.1.1 Design Bases The Fire Protection System is designed to achieve the following objectives:
1.
Provide fire protection in areas of the plant by means of portable extin-guishers and manual hose stations.
2.
Provide appropriate fire control strategy in areas of the plant containing equipment required to bring the unit to a safe shutdown condition.
3.
Provide automatic detection with local alarm and alarm and annunciation in the control room for areas of the plant containing combustibles.
4.
Provide automatic fixed fire protection systems over oil hazard areas.
5.
Provide automatic CO extinguishing systems in selected areas of the plant 2
with appropriate alarms and warning devices to alert personnel to pending discharges.
6.
Provide automatic Halon 1301 fire protection systems for document storage areas in the Service Building.
7.
Provide retaining walls, curbs, or drains in areas protected with sprin-klers to prevent spread of fires.
8.
Provide maximum protection against an unsafe condition or damage to safety class equipment due to failure of any portion of the Fire Protection System.
Manual fire fighting equipment (i.e., fire hoses and portable fire extinguish-ers) or activation of fixed water or gas extinguishing systems provide capabil-ity for control and extinguishment in the incipient stages of a fire, thereby minimizing potential consequences of fire in these areas.
{
Passive fire protection (i.e., fire barriers) including walls, ceiling / floors, l
fire rated doors and penetration seals reduce the possibility of fire crossing fire boundaries separating fire areas.
Confining a potential fire within a single fire area mitigates the scope of damage.
)
Inadvertent operation of or a crack in a fire suppression system would not preclude safe shutdown of the plant since redundant trains of equipment re-1 i
quired for safe shutdown are located in separate rooms, have adequate spatial separation or have appropriate water spray shielding.
In addition smoke control is provided by the installed ventilation and exhaust systems.
In the Auxiliary Building an exhaust system for numerous compartments j
containing equipment maintains a slight negative pressure within the building 1
