General analysis of breed-and-burn reactors and limited-separations fuel cycles
… using different fuels, structural materials, and coolants. This new approach allows important reactor and fuelcycle parameters to be approximated quickly, without the need for a full core design, including minimum burnup/irradiation damage and reactor fleet doubling time. Two general …

Rayleigh Flow of Two-Phase Nitrous Oxide as a Hybrid Rocket Nozzle Coolant
… hybrid rocket’s converging-diverging nozzle as a coolant. While this coolant system has proven effective empirically in previous tests, the physics behind the flow of the two-phase mixture is largely unexplained. This thesis provides a method for predicting some of its behavior by modeling it …

Modelling of Graphite Elements and Low Enriched Fuel Assemblies for a High Temperature Gas-Cooled Reactor
… blocks create the channels that guide the helium coolant flow and contain the fuel compacts in the HC-HTGR. Given the low tensile strength of graphite, FEA analysis is required for predicting stresses within these components. The stresses are evaluated using the ASME code for graphite …

Surface degradation and creep of Inconel 617 and Haynes 230 at high temperatures
… Generation Nuclear Plant (NGNP) project. The helium coolant in the primary circuit has been found to contain low levels of impurities (e.g. CO, CO2, H2O, CH4, and H2) after steady-state operation. This can lead to an environmental degradation of high temperature alloys used for internals and …

An Effective Methodology for Thermal-Hydraulics Analysis of a VHTR Core and Fuel Elements
… by 2030-2050. It is graphite moderated, helium cooled reactor that operates at an exit temperature of up to 1273 K, making it ideal for generating electricity at a plant thermal efficiency upwards of 48% and the co-generation of process heat for hydrogen production and other industrial …
