Waste management for spent resin from Reactor Experimental Chileno number-sign 1 (RECH-1)

A strategy is reported to find a waste form for temporary storage of spent resin arising from Reactor Experimental Chileno No. 1, RECH-1, according to radioactive waste management principles. As a first step, activity levels and contributions from long-lived fission products is obtained. The method that is developed is used to quantify the radioisotopes present in the resin to be allowed to follow them in the radioactive waste studies. As the activity is low, it is possible to find a way to dispose of large quantities of resin per drum. Two different processes were investigated: a mixtures technique and the double container immobilization method. Both were tested at laboratory and pilot plant scales. Results indicate that the double container method achieves great savings in economy of the management of spent resins
