6. High Performance Fuels for Water-Cooled Reactor Systems
Abstract : Investigation of nitride fuels and their properties has, for decades, been propelled on the basis of their desirable high metal densities and high thermal conductivities, both of which oer intrinsic advantages to performance, economy, and safety in fast and light water reactor systems. In this time several key obstacles have been identied as impeding the implementation of these fuels for commercial applications; namely chemical interactions with air and steam, the noted diculty in sintering of the material, and the high costs associated with the enrichment of 15N.

7. Fabrication and Testing of Doped Uranium Nitride as an Accident Tolerant Fuel Alternative
Abstract : Nuclear energy is a carbon-free energy source often considered less harmful to the environment than fossil fuels. However, accidents have shown that there are some safety concerns regarding nuclear energy that need to be continuously assessed and further improved. READ MORE

9. Open porosity fission gas release model applied to nuclear fuels
Abstract : Nitride fuels have gained a new interest in the last few years as both a candidate for GEN IV reactors and as accident tolerant fuels for current light water reactors. They however are decades behind oxide fuels when it comes to qualication and development of tools to assess their performances. In this thesis, such a tool is developed. READ MORE

10. Engineered microstructure composites as means of improving the oxidation resistance of uranium nitride
Abstract : Owing to its high uranium density and good thermophysical properties,uranium nitride (UN) fuel has been considered as a potential Accident TolerantFuel (ATF) candidate for use in Light Water Reactors (LWRs). However,the main disadvantage of UN is its low oxidation resistance in water/steamcontaining atmospheres at the operating temperatures of LWRs. READ MORE
