Ontario Hydro Research Division tritium handling system.

Abstract

A 1500 curie tritium laboratory is being constructed at Ontario Hydro Research Division. A special feature of this laboratory is the tritium storage and delivery system (TSDS). This system can dispense up to 125 curies of pure tritium gas per hatch to experimenter's facilities within the laboratory. The system consists of two uranium storage beds, a circulation pump, an assay volume, a vacc11m system and an analysis station. All components which routinely see high levels of activity are metallic. This paper describes the TSDS, outlines typical operating scenarios and discusses anticipated abnormal events and the recovery procedures.
