LCO 3.1 will not bi: met if die Smoke Detection Alm TraismifXal Sv-stern is no!
OPERABLE.. The absence of the fire detection acid alami fhnction in thc
RUiLDlhG 99 1 COMI'LEX waste cogginer storage area (i ,e,, Buildin~~~~9~!~d.
Corridor R) reduces the likelihood that the Fire Department wilt be notified that ;1
fire has occurred in this area. Tile Fire Department serves a credited prokction
fitnction in niitipating fires in the facility. Without the fire detection and aiai-rn
- function. tlheJikelihood of Fire llepartment response is decreased. The 2'jn>m&:;
Detection L41arm Transniitd System is only credited for those smoke detecrors in
Corridor B and in Building 596.
If the Smoke Detection Alarm Transmittal System is not OPERABLE. th2 fncil~t\

AFFECTED AREAS within eight-hours. If a fire watch is established. thc lirc
watch uartlv replaces the tirc detcidoii and ahmi fi~nctions of the Siiwog
Detection Aim Transmittal System with a fir? watch individual capable ot
providing the functions during watch tours. The fire watch individual is expr.c_tcd
to notifir the Fire Departrnerit in the event of a fire. either via fire phones or .UI
alternative method if the fire phones are unavailable.
'Rie cstabbiisliing of a fire watch in the AFFECTED AREAS does not urokidc
full-time tire detection and alarm capability. ,4 tire could initiate and prop3g;rtg
between tours of the fire watch Because the fire watch does not monitor all .ms
continuously and, therefore, does not completelv redace the fire detection nnd
almi c'wabiiitv ofthe Smoke Detection Alarm Transmittal Svstem, a rcductiori III
fire initiating event or propagation fieauencv is wamited. REQU 1 K 1: 1)
ACTION E.2 is identified to reduce the likelihood of fire initiation in thc
AFFECTED AREAS
While the fire watch does not provide the hll-time fire detection and darrg
