H2O-HTO isotope separation by distillation of water — a dynamics of HETP of SUS Dixon ring in a small packed column

AbstractA batch distillation of tritiated water ( ∼ 10 nCi/cm3) has been performed in a packed column of 1.6 cm inner diameter × 100 cm high. Packings were Dixon rings made of SUS. The concentration of tritium was measured at both ends of the column, and then the numbers of theoretical stages and the values of HETP were obtained as a function of the vapor rate within the column. The HETP value for the Dixon rings increased with the increasing vapor rate.

トリチウム水（約10 nCi/cm³）の回分蒸留を、内径1.6 cm、高さ100 cmの充填塔で実施した。充填物にはSUS製ディクソンリングを使用した。塔の両端でトリチウム濃度を測定し、塔内の蒸気速度の関数として理論段数およびHETP値を求めた。ディクソンリングのHETP値は、蒸気速度の増加に伴って増大した。
