Developing a computer code which solves concentration profiles simultaneously for vapor and liquid phases, we analyzed an effect of inner radius of wetted-wallcolumn on separative performances of water distillation for H<SUB>2</SUB>O-HTO isotope separation. Results through the code were compared with experiments for H<SUB>2</SUB>O-HTO wetted-wall water distillation under the total reflux condition with columns of 3 and 8mm of inner radius R. Total separation factors of R=3mm were larger than those of R=8mm, and the fact was well predicted by a numerical analysis. The total separation factors for theoretically maximum vaporization rate constant k<SUB>v</SUB>.<SUB>A</SUB>=1.57×10<SUP>4</SUP>cm/s gave a virtual its upper limit in the range of relatively large Reynolds number.
