Abstract

Present and future nuclear fuel cycles will rely upon controlling the complex chemistry of trace fission products and transuranium actinides. Knowledge of the chemical states of radionuclides in spent fuel and related materials provides a first line of understanding that may benefit waste disposal, fuel reprocessing, transmutation/recovery, and remediation of sites from weapons-related activities. Few techniques have proven more effective than X-ray Absorption Spectroscopy (XAS) for determining oxidation states and structural environments of elements in solids. We describe in this paper measurements of commercial spent nuclear fuel (CSNF) using XAS to better determine trace element chemistry in this material. The XAS results for Pu, Np, and Mo in CSNF are presented, along with a description of a novel bent-Laue analyzer concept, which, coupled with the high-brightness of the Advanced Photon Source synchrotron, made such measurements possible.
