Interaction of Actinide Matrices with Brine

Аннотация

It is suggested to dispose of radioactive wastes of nuclear energetics with long-lived actinides in the form of titanates and zirconates in boreholes up to 5 km deep. The low leaching rate of the waste imitator (Nd) from samples is shown during their interaction with chloride brine at 200°C. The elements in the liquid phase mostly occur in soluble form, and the role of their colloidal form is insignificant. Our results allow substantiation of a choice of promising materials for actinide immobilization.
