Cs$sup 137$ LOADING AND LEACHING OF SYNTHETIC ZEOLITE AND CLINOPTILOLITE COLUMNS

Technical Report ·
OSTI ID:4775852
A Decalso colunrn was loaded with synthetic 103-A tank supernatant solution spiked with 5% actual 103-A tank waste and diluted with an equal volume of distilled water. The column was washed with four volumes of tap watcr to simulate plant washing of the loaded zeolite and leached with several volumes of synthetic Missouri River water. This river water leaching resulted in elution of 0.63% of the Cs/sup 137/ from the Decalso in 20 column volumes. Eventual elution of inost of the Cs/sup 137/ must be assunred in an evaluation of possible hazards under the simulated conditions. Samples of Decalso saturated with synthetic 103- A waste were fired to 1500 and 2500 deg F at atmospheric pressure without the formation of crystalline compounds. Leaching with several volumes of synthetic river water indicated that clinoptilolite is somewhat more resistant to elution of Cs/sup 137/ than is Decalso. Clinoptilolite has potential for use as a Cs/sup 137/ transportation medium. (auth)
