Air Contamination of KUR

Abstract

The air contamination of caused dy the operation of Kyoto University Reserch Reactor has been investigated. At the power of the reactor of 5000KW, the radioactive gas production observed are about 160μCi/sec activated by the opened beam tubes and also about 200μCi/sec by the primary coolant contamination, respectively. And the producions of radioactive dust is about 0.0003μCi/sec. It is clear that these amounts of concentrations may be changed by the conditions of reactor room ventilation, conditions of primary coolant and reactor power.
