Pelletized waste form demonstration program, October 1979-March 1980
The main objective of this task is to evaluate several transuranic waste immobilization methods. During the first half of FY-1980, ash/cement and sludge/cement pellets were performance tested. In short-term radiolysis experiments with sludge/cement pellets, a very low hydrogen generation rate of 0.01 molecule/100 eV was obtained. Leachability testing of ash/cement and sludge/cement pellets containing plutonium-238 oxide in both brine and deionized water yielded a very low leach rate of < 10/sup -5/ (fraction leached) (g) (cm)/sup -2/ (day)/sup -1/. Pressed waste/cement pellets, therefore, appear to be an excellent final waste form based on leachability and radiolysis results. Design criteria were developed for the production waste pelletization line (PWPL) and documented. Equipment procurement for the PWPL was started, and installation will be continuing for several months.
