Structure determination of compounds for the immobilisation of Iodine-129 and Technetium-99

, , &
99Tc (half life 2.13 x 105 years) and 129I (half life 15.7 x 106 years) are abundant and long lived products of nuclear fission, with yields of 6% and 0.7% respectively for thermal fission of 235U. These radionuclides are of particular concern in closed nuclear fuel cycles, since the long half life and high production rate, combined with solubility and bioaccumulation. Future advanced nuclear fuel recycle strategies demand disposition of 99Tc and 129I in a...
