6850 Alternative Treatments 6850 Alternative TreatmentsTreatmentANO-1ANO-2PLPWF3Transient 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 described in the ERIN Fire Factors report submitted to the EPRI/NEI Review Group.

XXXXTransient 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 of transient type fire conditions existing in close proximity to targets of concern (submitted to methodology review committee).

XXXXTreatment of Ventilated Panels for Non-Suppression Probability.

XXCredit for reduction of zone of influence for panels with limited ventilation, used to support Multi-Compartment Analysis.XXHot Short Probability Reduction for Outside of a Panel Configuration (ANO-2 only)
