Abstract
A process of safe disposal, handling or storage of radwaste associated with nuclear power production is described. A feature of the invention is to incorporate the radwaste in a hardenable, matrix-forming mass employing a cement-type binding agent to which alkali or alkaline-earth silicate is added, among other things, to increase liquid absorption.
Claims9
In a method of processing radioactive wastes wherein a slurry of radioactive wastes and a cementing material is formed in a mixer and the slurry then transferred from the mixer to a storage and shipping container and allowed to harden therein, the improvement of increasing shipping efficiency by including in the slurry before hardening an alkali or alkaline earth metal silicate, and for each 100 parts by weight of the waste included in the slurry adding 25-70 parts by weight of the cementing material and 5-25 parts by weight of the silicate.
