Near-infrared spectroscopy has potential as a new suitable tool to detect tritiated water (HTO, T2O). We previously carried out the initial study with a single-walled cell system and got some spectra of tritiated water vapor. Because of the radioactive nature of tritium, tritiated water was decomposed into tritium gas and oxygen by radiochemical reactions, and there was a need for a reoxidizing system and other updates to improve tritium recycling and safety issues. Therefore, we developed a new double-walled cell system and tested its basic performance. The performance of the cell was found to be appropriate for the prolonged measurement of the spectra of tritiated water vapor.
