ATTA CHM LN T j THl-2 CHARCOAL FILTRATION SYSTEMS The Unit 2 Aux Building and Fuel Handling Building Exhaust Filtration Systems have experienced a wide range in air f l ow rates since the incident on 3/28/79 Doeration for each of these systems has varied from having two exhaust fans operational with one or two supply fans operational to having one or two exhaust fans operational with zero suopiv fans. This type of varied coeration has resulted in this wide range in flow rates. In evaluating the attached data on charcoal fi l t ra t i on sys tems, two design features must be acknowledged: 1. The bypass damoers in the Aux Building have been removed; therefore, all flow has gone through the charcoal #ilters. 2. The Unit I and 2 Fuel Handling Buildings are seperated by a shield wall that does not extend all the way to the building ceiling. Therefore, Unit I and 2 Fuel Handling Building interconnect which results in some cross venti-lation between the two otherwise seperate systems. I 6 O
