Tritium permeability was measured with T2 partial pressure ranging from 5.8 × 10−2 Pa to 6.8 × 10−2 Pa over the temperature range from 573 to 873 K. The obtained tritium permeability in polycrystalline tungsten was PT [mol m−1s−1 Pa−0.5] = (2.13 × 10−9)exp(−93.32 [kJ mol−1]/RT). This is one of the first tritium permeability data from any polycrystalline tungsten via a gas-driven permeation technique. The tritium permeability in polycrystalline tungsten was compared with the reported hydrogen isotope permeability in other polycrystalline tungsten.},
