Abstract
A tritium experimental system for 100 Ci/run was established at
the Hydrogen Isotope Research Center, Toyama University. The system has
two distinct experimental chambers: a tritium circulation system and an
exhaust-gas detritiation device. The former consists of tritium storage,
purification and gas chromatographic hydrogen isotope separation units.
The performance of the isotope separation unit was examined for 20 Pa⋅l,
a sample gas mixture containing protium, deuterium and tritium under the
conditions of operation temperature at 77 K and carrier-gas (Ne) flow of
50 cc/min. Six isotope compounds of hydrogen were reproducibly separated
within an adequate period of time (within 5000 seconds). In addition, the
relative sensitivities of the thermal conductivity detector could be determined
in-situ with the aid of an ionization chamber for detecting tritiated hydrogen
isotope molecules.
