Tritium Recovery at Fusion Facility 5.Development and Experience of Tritium Control in Heavy Water Reactor “ FUGEN ”

Abstract

Tritium is generated mainly from the activation of the heavy water moderator at Fugen. Its control is a key issue for heavy water handling technologies there. This paper describes the equipment considerations, methods of tritium monitoring, radiation work control, gaseous/liquid emission control, and personnel dose management for tritium that were developed and improved through the more than two decades of operation of the Fugen Nuclear Power Station.
