| 内容記述 | Air detritiation system of a fusion facility consists of catalyst reactors for tritium oxidation and a system to remove tritiated vapor from air. In an event of fire in the facility, the impact of gaseous impurities produced by polymeric materials on catalytic oxidation of tritium is one of the points to be evaluated. A point is the impact of reaction heat since gaseous impurities such as hydrocarbons are probable to combust in the catalyst reactors and heat of reactions is large. The distributions of temperature and concentration in a catalytic reactor is numerically evaluated using the thermophysical and chemical properties. The numerical analysis showed that the temperature in a catalytic reactor rose to 1173K by combustion of ethylene and hydrogen when air containing 1% hydrogen and 1% ethylene was fed in a reactor heated initially at 473K. Since the increase in temperature is large, additional technical consideration will be surfaced for design such as selection of material for a reactor, increase in tritium permeation and impact of excessively heated air on equipment located in the downstream. The heat removal mechanism needs to be designed for catalytic reactors. | |||||
