The U.S.
dh m==rt the defense-in-depth principle as applied to fire afety in Enclamr Feuer Plants. The U.S. explained that in order to aamare an acceptable level i
i of fire amfety, an adequate balance in the following principlas must

i be achieved :
l Preventing fires fra starting through the une of administrative ocotrols :
- Detmeting fires quickly thecush the application of early mrning fire / mneks detmetion arstmas, asppressing fires Wdch comar quickly thrcush the aplication of fixed fire extinguishang gatans and/or annual fire fishting manna, and limiting damase thecush the applicaticm of passive fire protmetion festaares ; and Designing Plant Safstr & stems ao that a fire Wiich starts in spite of the Fire Prevention Prtsram and burns for a armmMarable time in eita of fire asppression activities will not prevent assential Plant Safety Wstame fra being parfanned.

'!he U.S. discussed the fire pretmetion design critaria and guidelines imposed m U.S.
Naclent Power Plants to asaare safe shitdom capability is adequately protmeted. The U.S.
indiented that firs protmetien features are provided for stauctures, arstems, and l
coupments important to safe ahatdom, j
the U.S. diamaw how fire protmetim of safe shrtdom capability is I
achieved at U.S. facilities.1he U.S. emplained the following design l
1 approaches which are used to enaire that ene train of shttdom arMans are amintained free fztzn fire damage :
Separation of cables, equisment stad associated cira11ts of redundant trains ty a fire barrier having a 3-hour fire resistance rating ;

In additim, fire detmetion and autauntic fire messessica is required to be ~ Anstallad within the plant atom of armanra or

appressim is required to be Anstalled within the plant area of i
crmnarn.

' the U.S. also dia:nassed that if the above design apprendes oculd not be adequately implemented in a fire aren (i.e. amin Control'Bom),
i U.S.
facilities are required to install-an altamative shLitdom system independent of the fire area of annoorn. The U.S.
iM. icated i
tkat the perfcrannoe scals established for the altamative ah'.
functicms were as follows :
t
- Achieving and amintaining aaberition1 zenotivity canditions';
- Maintaining reacter coolant inventory 3 and 4
- Achieving and maintaining hot standty conditicms.
t
'ne U.S.S.R. presented an overview of their approach towards achieving and saintaining stable sNtdown'cxmdit.icns within the reactar in the I
1 event of a serious fire in the amin Control Bocus. The accpo of the diammaien primarily focused cm the plants empability of achieving the l
aktdom perfcamanna samla of reactivity ocatrol, reacter coolant ashes and short / 2cng term doony heat rummal.1he U.S.S.R. further stated that the=====+ul achievenant of the required functicas has bem incorporatal into the tasio design characteristics of the facility. This includes the provisica of three redundant- (safe sNtdcun) secnarity channels (trains) that aar be ocntrolled frtsa I
altarrate ocntrol panels located in a reente Icontien of the plant.

1he U.S. and U.S.S.R. techiaml specialists agreed that the suwisim of theas re&mdant trains of required systems enhanons tt.t ability to I
achieve the desired post-fire comrating cxxxiitims. It ias idao noted during the discucalens, however, that this design pidlant Wy alone does not eliminata the need for additicral analysis of the pchttially adverse effect.s of fire and that mach an evaluatica should address i,
