“…In first-generation fusion reactors, deuterium and tritium are used as fuel for a nuclear fusion reaction that produces 4 He, neutrons, and a large amount of energy, which can be used to generate electricity. However, tritium is a radioactive hydrogen isotope that decays to 3 He by emitting a beta particle with a maximum energy of 18.6 keV, and the half-life of tritium is 12.32 years. Therefore, this radioactive material must be handled in a multi-confinement system.…”

“…1,2) This conventional tritium removal system is used at tritium facilities worldwide. [3][4][5][6] To reuse the adsorbent, it must be periodically regenerated to remove the collected water. The conventional regeneration method is temperature swing regeneration, in which the adsorbent is exposed to dry air heated to more than 500 K. The adsorbent is then cooled with a cold gas stream.…”

A synthetic honeycomb type A zeolite adsorbent was regenerated through microwave irradiation in a single-mode cavity microwave at 2.46 GHz. The regeneration mechanism was investigated by comparing the heating properties, thermogravimetric properties, and dielectric properties of the synthetic zeolite samples. The hydrated zeolite sample was easily heated to over 200 °C, although a difference in the impedance matching frequency of only 0.01 GHz sharply reduced the maximum heating and increased the regeneration time. The adsorbed water in the hydrated zeolite initially acted as a heating agent by absorbing microwave energy, because the dielectric loss factor of water is higher than that of synthetic zeolite around 2.45 GHz. From 50 to 250 °C, the zeolite itself also absorbed microwave energy.
