Tritium present in H2 or D2 1.7×10-2 Ci/mol,
was enriched using a hot-wire type vertical glass thermal-diffusion column with a gas reservoir on top.
Four columns with different diameters (mmΦ), 8, 20, 30 and 41, were tested, while the temperature of
a DC heated nichrome wire along the axis of each column was changed over a range from 200 to 450℃.
The maximum equilibrium separation factors in hydrogen and in deuterium were 17 and 4.5 respectively.
The optimum diameters were calculated by a modification of Waldmann's equation which can be used
for the separation using parallel plates.
