Systematic chemical decontamination using IF gas

Hata, Haruhi   ; Yokoyama, Kaoru; Sugitsue, Noritake

IF treatment technique belongs to the system decontamination technology. It has the high performance decontamination technique for the plant that deposits the uranium intermediate fluoride, for example, UF, UF, UF, and UF, which exist in the uranium enrichment plant by the Gas Centrifuge. The characteristics of IF treatment, the secondary waste is just an IF and little adsorbent. In addition, this IF is possible to reuse as a materials for makings new IF gas. According to that IF treatment is the simple method using chemical reaction, we hardly need to care about secondary reaction with the exception of the reaction with IF gas and the uranium intermediate fluoride. This is very important feature when applying to a large-scale plant.
