New coolants, new fuels: A new generation of university reactors
Here’s an easy way to make aging U.S. power reactors look relatively youthful: Compare them (average age: 43) with the nation’s university research reactors. The 25 operating today have been licensed for an average of about 58 years.

Extended x-ray absorption fine structure(EXAFS) spectroscopy can be used to probe thelocal atomic environment around actinide atoms in avariety of systems. Uranium LIII-edge spectra wereobtained on an in-lab rotating anode EXAFS facility.Spectra of crystalline UO2F2 and aqueous solutionscontaining hexavalent uranium ions show structureassociated with two separate shells of surroundingatoms. With the use of fluorescence detection techniques and more research directed toward deter¬mining backscattering amplitude and phase shiftparameters, it is anticipated that EXAFS will becomea powerful quantitative technique for structure stud¬ies in heavy atom systems.
