Finding

Title

Relay Room Carbon Dioxide Fire Suppression System and Control Room Envelope Potentially Affected by HELB

Description

During the inspectors review of the relay room carbon dioxide (CO2) fire suppression system actuation failure, the inspectors identified that control cabinets for both the CO2 fire suppression actuation system and the relay room ventilation damper ACC-22, are mounted on the outside of the SR east wall of the relay room and exposed to the turbine building. The control cabinets could be exposed to steam from a nearby 30-inch steam header if a crack were to develop. The inspectors were concerned that the potential existed to actuate the relay room CO2 fire suppression system and/or cause one of the relay room ventilation dampers to open, complicating the control room response to the small steam break. At the conclusion of this inspection period, the licensee was evaluating the issue; the inspectors needed additional information to determine if a performance deficiency existed. As a result, this item was considered unresolved (URI 05000305/2012005-05, Relay Room Carbon Dioxide Fire Suppression System and Control Room Envelope Potentially Affected by HELB).
