Description

An experimental apparatus for enrichment of 85Kr, which consists of 8 metallic separation columns with hot wire, was designed and constructed for the development of enrichment technique of 85Kr by thermal diffusion method. Total effective length of the column is 18.4 m and maximum amount of 85Kr treated is 200 Ci. The method for measuring temperature of the hot wire and the optimal material used for the hot wire were investigated prior to design this apparatus. It was possible to measure the temperature of the hot wire with fairly good precision by specific resistance method. Of 8 kinds of metallic wires, tungsten wire was chosen as an optimal hot wire, by taking into consideration of 7 terms for the selection of the hot wire. (author)
