Electrochemical methods were used to study the initial dissolution and leaching behavior of spent-fuel fragments. The initial dissolution rate and the nature of the surface film of the spent fuel was shown to be compatible with those of single-crystal UO/sub 2/ surfaces. Thus, studying the behavior of UO/sub 2/ may provide an understanding of spent-fuel leaching mechanisms. Also, the study showed that spent-fuel leach data and dissolution kinetics may be obtained from the electrochemical methods described.
