The Effects of Radiation Damage on Synroc
The basic objective of the SYNROC method of immobilizing high level nuclear reactor wastes (HLW) is to incorporate the fission products and actinides as dilute solid solutions in the crystal lattices of synthetic minerals. These minerals are closely related to natural minerals known to have been stable in a wide range of geological and geochemical environments for periods of more than 109 years. The minerals employed in SYNROC formulations designed to immobilize HLW from reprocessed fuel rods of power reactors are hollandite (BaAl2Ti6O16), zirconolite (CaZrTi2O7), and perovskite (CaTiO3). It has been demonstrated that these minerals have the capacity to accept nearly all HLW fission products and actinides into solid solutions in their crystal lattices (1).
