Metal waste form corrosion release data from immersion tests.

Testing to evaluate the suitability of waste forms developed for electrometallurgically treated spent sodium-bonded nuclear fuel for disposal in the Yucca Mountain reporsitory.

“…An empirical model has since been developed for MWF degradation based on the results of electrochemical and dissolution tests with several MWF materials (Bauer et al, 2001;Bauer et al, 2002;Fink et al, 2000;Snyder et al, 2004). That model incorporates the dependencies on temperature, pH and Cl -that were measured in test environments ranging from pH 2 to pH 12, 25°C to 90°C, and about 0 to 10,000 ppm Cl -.…”

“…Expressions were determined by assuming simple linear or quadratic dependence on these variables, using a least-squares fit of the experimental data, and minimizing the number of free parameter combinations. The dependencies, which were determined by fitting results in Johnson et al (2001) and Snyder et al (2004), are given in Eqs. V-7a and V-7b (see Bauer et al, 2001;Bauer et al, 2002): (V-7b) The fitted dependencies in Eq.…”
