Summary

This project seeks to understand the microscopic effects of radiation damage in nuclear waste forms. Our approach to this challenge encompasses studies of crystals and glass containing short-lived alpha- and beta-emitting actinides with electron microscopy, laser spectroscopy, and computational modeling and simulation. Much of our effort is to probe alpha-decay induced microscopic damage in 17-year old samples of crystalline yttrium and lutetium orthophosphates that initially contained ≈1% of the alpha-emitting isotope Cm-244 (18.1 y half life). Studies also are conducted on borosilicate glasses that contain Cm-244, Am-241, or Bk-249, respectively. Our goal is to gain clear insight into accumulated radiation damage and the influence of aging on such damage, which are critical factors in the long-term performance of high-level nuclear waste forms.
