LCO 3.1
The Automatic Sprinkler System provides a credited safety function to suppress
postulated fires occurring in the BUILDING 991 COMPLEX Office Areas and
reduce the likelihood that Office Area fires will impact waste container storage
areas The Automatic Sprinkler System is expected to actuate automatically and
mitigate the Office Area fire to prevent fire propagation into contiguous waste
container storage areas. The Automatic Sprinkler System also provides a credited
safety function to mitigate the effects of any fires that may occur in waste
container storage areas. An additional safety function is provided by the Flow
Alarm Transmittal System which notifies the Fire Department of Automatic
Sprinkler Svstern actuation, initiating Fire Department response to extinguish the
fire and mitigate any fire related impacts. The Smoke Detection Alarm
Transmittal Smem arovides a svstern to detect and reoort fircs non-sr>rinklered
waste stowe anas of the BUILDING 991 COMPLEX to facilitate response of the
Fire Demrtnient. Receipt of the dann from the Smoke Detection Svsteni will
initiate Fire Department response to extinwish the fix and mitigate anv fire
related imDacts. ReceiDt of the alm from the Smoke Dctechon Svstem will also
facilitale initiation of an LS/DU' announcement to notifk personnel inside
Building 991 of the fire.
The BUILDING 991 COMPLEX Automatic Sprinkler System and Flow:'Smoke
Detection Alarm T&mittal Systems shall be OPERABLE.
For the Automatic Sprinkler System to be OPERABLE, the system must be
capable of automatidy supplying water to waste container storage areas and the
Office Area of the BUILDING 991 COMPLEX sufficient to suppress fire growth
in those areas following the initiation of fires with significant growth potential
For the Flow Alarm Transmittal System to be OPERABLE, the system must be
capable of detecting Automatic Sprinkler System use and providing a signal to the
Fire Dispatch Center andor the Central Alarm Station. For the Smoke Detection
Alarm Transn~ttai System UJ be OPEWLE. the system must be wable of
deteminrr a fire and Drovidina a simal to the Fir6 Disuatch Center an&'or Central
Alann Station.
