DS must be designed to make sure of detritiation when an extraordinary event such as fire happens. DS comprises catalytic reactors to oxidize tritium and a system for removal of tritiated vapor. One of chemical components of tritium to be oxidized by the catalytic reactors is tritiated methane. Tritiated methane is oxidized by a high temperature reactor at 773K generally. Assuming that an accidental release of tritium and production of hydrocarbons by combustion of cables in case of fire occurs simultaneously, tritiated methane should be oxidized at lower temperature from the viewpoint of mitigation for temperature runaway of a catalytic reactor by heat of reaction of hydrocarbons combustion and tritium permeation through a catalytic reactor of DS. In addition, there is concern generation of tritiated methane by the reaction between tritium and methane in a catalytic reactor at low temperature. In the present study, we investigated experimentally a method of processing tritiated methane by a catalytic reactor at low temperature. Our experimental investigation indicated follows: 1) a generation of tritiated methane was sufficiently small; 2) tritiated methane could be oxidized below 773K by optimization of catalyst.
