6850 Alternative Treatments Treatment ANO-1 ANO-2 PLP WF3 Transient combustible HRR. Use a lower HRR for a postulated transient fire. Instead of using the HRR for transients as shown in NUREG/CR-6850, Table E-1, Case 8, the HRR for Case 7 is used. The basis for this is X X X X described in the ERIN Fire Factors report submitted to the EPRI/NEI Review Group.

Transient Combustible Ignition Frequency - Use of a weighting factor applied to transient fires to reflect the reduced probability of a fire impacting critical targets based on procedural controls and the reduced likelihood X X X X of transient type fire conditions existing in close proximity to targets of concern (submitted to methodology review committee).

Treatment of Ventilated Panels for Non-Suppression Probability. X X Credit for reduction of zone of influence for panels with limited ventilation, used to support Multi-Compartment X X Analysis.

Hot Short Probability Reduction for Outside of a Panel Configuration (ANO-2 only) X 7
