【 摘 要 】

The overall goal of this project was to study key scientific issues related to the long-term stability and performance of crystalline waste forms under consideration for containment and disposal of nuclear waste. Our research efforts were focused on the effects of transmutation of 137Cs to 137Ba in crystalline pollucite (CsAlSi2O6). This transmutation issue is important to all crystalline nuclear waste forms, including spent fuel. In the research completed, we studied both surrogate samples and actual, 137Cs pollucite radioactive samples ({approx} 20 years old). Analytical techniques that pushed the envelope of existing capabilities were used, leading to limited, but significant, progress. This research was done at Argonne National Laboratory in collaboration with Pacific Northwest National Laboratory.
