| 内容記述 | The potential halogen effects on Detritiation System (DS) was investigated. DS is required to remove tritium from the atmosphere of a nuclear containment even in an event of fire. Basically several precautions should be taken to avoid the formation of halogenated gases by fire since there is concern that halogen can cause loss of both catalyst and water absorber activities. However, halogens will be present in many facility components of a fusion facility such as cables and electrical cubicles which are in direct contact with room atmosphere. Combustion products from halogenated hydrocarbons by fire will be a mixture of many compounds such as CO, CO2, NOx, HTO, HCl. We have already presented the effect of HTO, H2O, hydrocarbons, CO, CO2 on DS. In this study we assessed the impact of halogen on DS and proposed a mitigation measure. HCl and Cl2 caused decrease in activity of a platinum catalyst. We make clear a mitigation measure by poisoning with halogenated gases is the application of a noble catalyst alloyed with platinum and palladium. The outstanding proof of the alloyed catalyst was measured with molecular iodine which is known as the worst halogen to poison catalyst. Chlorine gas caused decrease in water absorbing capacity of molecular sieve absorbent. The data in this paper affords the perspective on the limited use of halogenated materials in a fusion facility. | |||||
