Total CDF 1. -UH (a)Severity Factors. S. ,f,r.e,seyeqityfactor is a fractional value (between 0 and 1)that is used to adjust fire frequency estimates to reflect some specific mitigating pattern of.Y behaviorof the fire event. ..The severity factor is applied to reflect a split in large versus small fires.

d~pi chargersAnite li'a,# building t ofg ; v-o.a.sth t~~~~yi __an~l~si_ pa a , i Probability of automatic suppression system being unavailable, P1 - As discussed in Section 3(b), the probability of pre-action sprinkler system in fire zone 98-J being unavailable is assumed to be 0.05 for the normal operating state based on the EPRI database (EPRI FIVE report, page 10.3-7). This unavailability value include the consideration for failure of the system to operate on demand and the system being out of service at the time of a fire (due to shut control valve, etc.). Infire zone 99-M, no automatic fire suppression system is provided. Therefore, the P1 value was assumed to be 1.0.
(c)Manual Suppression by Fire Brigade, P2 - Recent fire drills performed on fire zone 100-N,which is adjacent to fire zone 99-M, indicated that the response times of the entire fire brigade arriving at the fire zone averaged less than 10 minutes. wlhere are two access ala ypoints-to.the fire zones -which are easily-accessible by-the fire-brigade respons.ej.geams" Based on these considerations, it was assumed that any fire scenario requiring greater
- than 20 minutes to sustain cable damage may be suppressed by the fire brigade.
Hawever,..the SPLB fire modeling analyses indicate that severe, fires with. HRR greaterp than 400 kW in fire.zones.90-Jand.9 M could cause.damage to the overhead cables in;I
-approximately 19 minutes and 10 minutes, respectively. -Thvrefore, the failure prob&bilit of manual suppression by the fire brigade associated with severe fires was estimated to be b.5in this risk analysis.
(d)Conditional Core Damage Probability, P3 - For the fire scenarios in fire zone 98-J involving ignition of the electrical cabinets, battery chargers, ventilation systems, and fire protection panels, it is assumed that one equipment train would be available to perform mitigating functions because a one-hour rated barrier surrounds the Red train AC instrumentation power supply cables. Although other Red train power cables in fire zone 98-J are unprotected, the estimated time of 19 minutes to cable damage allows the arrival of the fire brigade in 10 minutes to control the fire. It is not likely that a fire from these sources would damage both equipment trains at the same time. Therefore, the CCDP

- ANO recommends that symptom-based procedures be used to guide manual actions in any future rulemak-ing by NRC
- ANO firmly believes that their use of manual actions for IIIG2 redundant safe shutdown areas is consistent with NRC regulations and guidance
- ANO believes that the b/f panel finding was flaved because we did not adequately consider the licensing basis for their facility
- they attempted to lay out their understandingfjtheir licensing basis at this information exchange meeting
- they asserted that their survey ofother re-74jan Idicated they wre.not outliers; there are at leas thefacilities who have similar manual action methodology without prior NRC approval
- the meeting was adjourned - NRC will consider the licensee's perspective as we determine how to process the finding in the ROP John Hannon October 3, 2002
