Fabrication and microstructural analysis of UN-U sub(3)Si sub(2) composites for accident tolerant fuel applications
In this study, U sub(3)Si sub(2) was synthesized via the use of arc-melting and mixed with UN powders, which together were sintered using the SPS method. The study revealed a number of interesting conclusions regarding the stability of the system - namely the formation of a probable but as yet unide...

| description | In this study, U sub(3)Si sub(2) was synthesized via the use of arc-melting and mixed with UN powders, which together were sintered using the SPS method. The study revealed a number of interesting conclusions regarding the stability of the system - namely the formation of a probable but as yet unidentified ternary phase coupled with the reduction of the stoichiometry in the nitride phase - as well as some insights into the mechanics of the sintering process itself. By milling the silicide powders and reducing its particle size ratio compared to UN, it was possible to form a high density UN-U sub(3)Si sub(2) composite, with desirable microstructural characteristics for accident tolerant fuel applications. |
