The Test Reactor Area (TRA)-770 Stack Radiation Monitoring System measures the air exhausted from the Advanced Test Reactor (ATR) for radioactivity and activates a ventilation shutdown if limits are approached or exceeded. Replacement parts are unavailable and age-related calibration difficulties have caused an increase in maintenance activities and system shutdown. This equipment is obsolete and needs to be replaced.
