Modeling of Thermal Transport Properties in Metallic and Oxide Fuels
… performance property not only for current UO2 oxide fuel based light water reactors but also important for next-generation fast reactors that use U-Zr based metallic fuels. In this work, the thermal transport properties of both UO2 based oxide fuels and U-Zr based metallic fuels have been …

Molecular Dynamics Studies of Grain Boundary Mobilities in Metallic and Oxide Fuels
… reactors, the most common fuel is uranium dioxide (UO2), an oxide ceramic. There is also ongoing research examining uranium-based based metallic fuels, such as uranium-molybdenum (U-Mo) fuels with low uranium (U) enrichment for research reactors as part of a broader effort to combat nuclear …

Economics of nuclear fuel cycles : option valuation and neutronics simulation of mixed oxide fuels
… scenarios economically comparable. For Uranium Oxide (UOX) and Mixed Oxide (MOX) fuels, a traditional way to achieve this is to evaluate both fuels on the deterministic premise that the fuel will be sent to geologic disposal once spent. This methodology often leads to higher costs for cycles …

Modelling of thermo-mechanical and irradiation behavior of metallic and oxide fuels for sodium fast reactors
… to model the irradiation behavior of metal and oxide fuels in sodium cooled fast reactors is developed. Modeling capability was enhanced by adopting a non-empirical mechanistic approach to the extent possible, so that to increase the ability to extrapolate the existing database with a reasonable …

Formation and growth of irradiation-induced defect structures in ceria
… growth of radiation-induced defect structures in oxide fuels. Due to the natural complexity of oxide fuels, which consist of both a metal sublattice and an oxygen sublattice, radiation effects are much more complex in oxides than in metals. As a result, there are many radiation effects that are …

Optimization of hydride fueled pressurized water reactor cores
This thesis contributes to the Hydride Fuels Project, a collaborative effort between UC Berkeley and MIT aimed at investigating the potential benefits of hydride fuel use in light water reactors (LWRs). This pursuit involves implementing an appropriate methodology for design and optimization of …

Assessment of innovative fuel designs for high performance light water reactors
… since this may better resemble transmutation fuels of the future. It is found that the use of plutonium-bearing mixed-oxide fuels further exacerbates the high fuel temperatures. The silicon carbide cladding is predicted to have more favorable performance when used for internally- and …

Wire wrapped fuel pin hexagonal arrays for PWR service
This work contributes to the Hydride Fuels Project, a collaborative effort between UC Berkeley and MIT aimed at investigating the potential benefits of hydride fuel use in light water reactors (LWRs). Core design is accomplished for both hydride and oxide-fueled cores over a range of geometries via …

Feasibility of breeding in hard spectrum boiling water reactors with oxide and nitride fuels
… aspects of using nitride fuel in place of oxides in Pu-based high conversion light water reactor designs. Using the higher density nitride fuel hardens the neutron energy spectrum and results in higher breeding ratios. The state-of-the-art high conversion light water reactor, the …
