Tritium storage development. Progress report No. 9, July--September 1976. [Tritiated concrete-polymer]
Lysimeter testing of the polymer impregnated tritiated concrete (PITC) specimens at the Savannah River Plant has continued. After thirty-one weeks, a constant average tritium fraction release rate of 1.16 x 10/sup -6/ day/sup -1/ was reached in the percolate water with no measurable release into the air. Data from this experiment projected to long-term tritium releases estimate that a complete tritium release from the PITC will require 2,370 years and that the maximum fraction of the initially contained tritium present in the environment will be 2.76 x 10/sup -3/ after 17.7 years. A duplicate PITC specimen is in static leaching in distilled water. After 295 days, a constant tritium fraction release rate of 1.89 x 10/sup -5/ day/sup -1/ was determined for this specimen. Development of the injector technique for PITC production has proceeded with the fabrication of a large-scale 27 gallon PITC casting. This casting was sectioned longitudinally and examined for its physical appearance, integrity, and polymer distribution. A representative of Monsanto Mound Laboratory spent one week at Brookhaven National Laboratory for PITC production technology transfer.
