The physical and chemical form in which radioactive waste is immobilised for handling, storage or disposal. Its durability is distinct from that of its container and surrounding engineered barriers.
A waste form designed using durable mineral structures as hosts. A natural analogue motivates a design but does not substitute for tests of the actual radioactive composition.
A titanate host represented by . strontium can replace calcium; other ions require suitable charge balance.
A tunnel-structured titanate host, represented by , used to incorporate large cations such as caesium with appropriate charge compensation in a crystal.
A family of mineral-analogue ceramic waste forms. Different titanate phases accept different waste ions by solid solution; phase assemblage is tailored to the waste inventory.
A multiphase Synroc formulation with zirconolite, hollandite, perovskite and titanium-oxide phases. The mineral hosts distribute different radionuclides rather than requiring one lattice to accept the entire inventory.
