The Radwaste/Reactor Building Vent Gaseous Effluent Radiation Monitor is necessary for accident assessment and is credited for Emergency Action Level (EAL) classification. The inability to classify an EAL due to the out-of-service Radwaste/Reactor Building Vent Gaseous Effluent Monitor is considered a loss of emergency assessment capability and is reportable per 10 CFR 50.72(b)(3)(xiii). | The Radwaste/Reactor Building Vent Gaseous Effluent Radiation Monitor is necessary for accident assessment and is credited for Emergency Action Level (EAL) classification.
