<![CDATA[Uranium waste generated
from the utilization of nuclear technology on radioisotope production, nuclear fuel production, calibration of
fuel post-irradiation, and the purification of uranium from yellow cake. Uranium is a long-lived radionuclides
and hazardous if it was entered in human body, thus requiring appropriate treatment with high safety. The
processing conducted by separated the uranium which was contained on waste with ions exchange
process. Uranium has been separated, later then immobilized with the polymer. The study of simulation
uranium waste processing using an Alumina Silica Phosphate (ASP) has been conducted. Simulation
uranium waste with the concentration of 0,05 g/l was contacted to ASP with contact timer and pH as a
parameters. The Alumina Silica Phosphate which saturated with uranium, later then immobilized with epoxy
resin polymer by total of waste contents as a parameter. The immobilization was conducted by mixing ASP
which saturated with uranium and epoxy resin. The study showed that the best composition of ASP was
obtained at the ratio of 1:1, contact time of 15 minute, and pH of 7 with absorption of uranium about 93,5%.
The characteristic of polymer and the immobilization waste showed that optimum of waste content is 20%
of weight with the density of 1,0538 g/cm3; compressive strength of 19,96 kN/cm2 and there was not
detected the leaching of uranium which out from the polymer-waste. Therefore, ASP can be used on
processing of uranium waste and could be suggested to be applied on Radioactive Waste Management
