5B.7 FIRE PKOTECTlON BASES
5B.7.1 Requirement for Fire Protection BASES
The safetv analvsis places aeat importance on a combustible material control program to
ensure that large fires do not occur in waste container storaee areas. Postulated accident
scenarios that specifv the Fire Protection promam include facilitv fire, facility
explosions. and criticalities.

Determination of acceptable combustible material * loading in various areas and
maintaining - the facility in corneliance with the determination are kev elements of
the control of combustibles in the facilitv. Specific controls in the combustible
control DroEtram are identified in AC 5 3
An ignition source control program accommodates changes occurring in the facilitv
(maintenance. decommissioning. equiDment removal. etc.) These changes may
reauire ignition sources (spark:heat/flame producing work) as art of the work
package. In order to ensure that imition sources are controlled in the facilitv. given
the transient nature of many ignition sources. work involving spark/heat&.m e
producing work will be controlled. This control can take the form of a hot work
permit Drocess.
LCO 3.1 rsauires implementation of fire watches during conditions when the
Automatic Surinkler Svstem and Flowkhioke Detection Alarm Transmittal System
is not operable. In order to ensure that fire watches are controlled in the facilitv, the
fire watch will be established in accordance with Site requirements.
The Fire Department serves a credited protection function in mitigating fires in the
facilitv. The Fire Deoartment also serves to mitigate facility flooding and water
damaqe due to actuation of the Automatic Sprinkler Svstem. The loss of this
knction tends to increase the likelihood of large fires in the fire analysis.
33.7.3 Snecific Controls or Restrictions
The fire ex3inmishers mevent a small fire from pr-oDagating. into a large fire in the
waste container storage areas. The fire extinguishers are credited in Facility Fire
Scenarios 1 through 4. The temporaw loss of a fire extinguisher (i.e.. from the time
the Fire DeDartment is notified until the fire extinguisher is redaced) within the
waste storage areas is not expected to siniijcantlv increase the likelihood of a sniall
fire prooagating into a large fire Therefore. no other rewired actions are specified
when a fire extinwisher is found to be out of compliance with reauireinents
