A reverse osmosis process has been found to be effective for the separation of radiocontaminants from ammonium diuranate effluents in a uranium metal plant. Pilot-plant-scale experiments were conducted using cellulosic membranes in a plate module system and actual plant effluents containing more than about 40,000 ppm of ammonium and nitrate species and having radiocontaminants corresponding to specific activities of about 10[sup [minus]3] Ci/m[sup 3] beta/gamma emitters. The results indicated that more than 95% by volume of the treated effluents were within disposal limits, while the remaining contained the concentrate, which can be treated for possible containment. 6 refs., 2 figs., 5 tabs.
