Data summary for nominal 500 (micro)m DUO2 Kernels

This document is a compilation of characterization data obtained on the nominal 500 (micro)m DUO2 kernels produced by ORNL for the Advanced Gas Reactor Fuel Development and Qualification Program to satisfy the FY03 WBS 3.1.2 task milestone No.2.2 kg of kernels were produced and combined in two composite lots. DUN-500 was a 1630 g composite sieved between 500 ± 2 (micro)m and 534 ± 2 (micro)m ASTM E161 electroformed sieves. DUN-482 was a 385.6 g composite sieved between 482 ± 2 (micro)m and 518 ± 2 (micro)m ASTM E161 electroformed sieves. Size, shape, density, and microstructural analysis were performed on a 100 g sublot (DUN-500-S-1) riffled from the DUN-500 composite. Size and shape were also measured on a 100 g sublot (DUN-482-S-1) riffled from the DUN-482 composite. For comparison, analysis was also performed on kernels extracted from the German reference fuel EUO 2358-2365 (AGR-06).
