Precipitation of uranium and Plutonium from alkaline Salt solutions

摘要

Addition of sodiumhydroxide to radioactive waste solutions produced a heterogeneous mixture of solids that exhibit different settling characteristics. Plutonium effectively coprecipitated with iron and uranium, and uranium with iron. Aluminum proved ineffective as a coprecipitating agent for either plutonium or uranium. Coprecipitation of uranium and plutonium occurs when The mole ratio of coprecipitating agent to actinide ex- Ceeds 1500.
