Spent pressurized-water reactor (PWR) and boiling-water reactor (BWR) fuel rods from three reactors were examined by hot cell periscope, energy dispersive x-ray analysis, and scanning electron micrography. In the case of fuel from the Quad Cities reactor it was possible to develop a complete particle size distribution. It was found to be log-normal, with a median geometric diameter of 3 μm and a standard deviation of 1.87 μm.
