Solidification of Spent Ion-Exchange Resin Pulps with Aid of Polymer Binders

Abstract

The results of studies of the physical and chemical properties of samples obtained during solidification of simulators of spent ion-exchange resin pulps with the use of polymer binders are presented. Investigations were conducted for pulps simulating heterogeneous radioactive wastes from the Kursk NPP. It is shown that the physical and chemical properties of the final compounds and the technological processes used to obtain them correspond to the requirements of solidified radioactive waste sent to storage or disposal. The surface of the samples is uniform and the components are distributed uniformly. Water resistance and radiation resistance tests showed that the mechanical strength of the tested samples is almost identical to the initial strength. It is shown that the mechanical load at which plastic deformation of the polymer compound occurs is a factor of two larger than and the leach rate does not exceed the established value.
