Tritium waste control, January - March 1978
Abstract
The combined electrolysis-catalytic-exchange pilot system was modified to improve the reliability of the unit for continuous operation. An experimental run for 60 consecutive hours using a single catalytic exchange column was made to estimate values of height of a transfer unit and height equivalent to a theoretical plate for the pilot system. The calculated values were in agreement with existing data from a bench-scale system. Further experiments were performed with the cryogenic hydrogen isotope distillation system, this time using H2-HT mixtures. Two experiments were successful in separating gaseous hydrogen containing tritium from tritiated water. Triplicate samples of cement, cement-plaster (1:1 ratio by weight), and cement-plaster (1:1 ratio by volume) were injected with 386 Ci of tritium, cured for five days, and then impregnated with catalyzed styrene monomer. After polymerization, the samples were put into a test program to measure the tritium release. No differences were noted from the data on these groups until the polyethylene bottle was removed.
