Study on the development of ADS-doped UO{sub 2} pellet technology for high burnup nuclear fuel

Technical Report:

Abstract

The ADS-doped UO{sub 2} pellet process has been reviewed and preliminarily developed to confirm the properties of ADS-doped UO{sub 2} pellets including average grain size and open porosity. The masterblending concept was employed to mix ADS powder with UO{sub 2} to make good homogeneity in the mixed powder. The pellet samples were then prepared with the developed process to characterize the ADS-doped UO{sub 2} pellet. Average grain size was increased by 2-3 {mu}m and open porosity decreased compared to the undoped UO{sub 2} pellet. In the study of ADS properties, ADS was decomposed at fairly low temperature and crystallized to {gamma}- and {delta}-A1203. In the ADS-doped UO{sub 2} sintering, bimodal curve was observed in sintering rate curve and no new phase formation was observed but the UO{sub 2} peaks were shifted slightly to the high angle in the X-rays diffractogram.
