A stand-alone system was developed for monitoring process support services and tritium levels in gloveboxes, room air, room exhaust ducts, and stack exhaust. Sixty tritium monitors were built and interfaced to a Health Physics control room where all tritium levels are displayed and abnormal conditions appear as alarms on large display boards. The control room was designed for full remote control of all monitors, with the exception of those for gloveboxes, as well as for control and alarm display of many other functions, including the purge rate for glovebox atmosphere and the selection of room air discharge to stack or to a tritium cleanup system. The monitoring system is interfaced to a data gathering computer and an automatic dialing alarm system.
