Data Summary for Nominal 350 ?m DUO2 Kernels
- ORNL
This document is a compilation of characterization data obtained on the nominal 350 {micro}m depleted uranium oxide kernels (DUO{sub 2}) produced by ORNL for the Advanced Gas Reactor Fuel Development and Qualification Program under task 3.1.2. Samples were riffled for analysis from a 100 g batch (designated as DUN350-1), which was riffled from the 3.4 kg composite lot of DUO{sub 2} kernels (designated as DUN350). Table 2-1 contains a summary of property measurements in comparison to the current acceptance criteria for depleted 350 {micro}m UO{sub 2} kernels. All the criteria were met with the exception of the 95% confidence criteria on the impurity levels, which was only measured on a single small sample. In addition, microstructure was analyzed by scanning electron microscopy (SEM). The grain size was less than 10 {micro}m across in the plane of the cross section and typically about 5 {micro}m. SEM micrographs also provided evidence of closed pores that were less than 0.25 {micro}m in diameter.
