Surrogate Model Optimisation for PWR Fuel Management
Pressurised Water Reactor (PWR) fuel management is an operational problem for nuclear operators, requiring solutions on a regular basis throughout the life of the plant. A variety of conflicting factors and changing goals mean that fuel loading pattern design problems are multiobjective and, by …

A one-dimensional fuel burnup model of a PWR
… burnup model of a Pressurized Water Reactor (PWR) was developed based on one-group diffusion theory and used simple thermal cross sections. A computer program which simulates the depletion of the core of a PWR was written based on this model. The basic idea was to develop a fuel depletion …

Reactor physics assessment of thick silicon carbide clad PWR fuels
… 4-loop Westinghouse pressurized water reactor (PWR). A new program, CSpy, has been written to use CASMO/SIMULATE to conduct optimization searches of burnable poison layouts and core reload patterns. All fuel/clad combinations have been modeled using 84 assembly reloads, and Thick SiC clad …

Experimental and Computational Study of Roughened Surface For PWR Rod Bundles
<p>PWRs fuel assemblies utilize spacer grids with flow mixing vanes to augment the coolant turbulence and improve heat transfer from the fuel rods. However, in the regions where the turbulence due to mixing vanes is the lowest, the heat transfer is the worst, resulting in higher temperatures and …

Modeling the performance of high burnup thoria and urania PWR fuel
Fuel performance models have been developed to assess the performance of ThO₂-UO₂ fuels that can be operated to a high burnup up to 80-100MWd/kgHM in current and future Light Water Reactors (LWRs). Among the various issues raised in high burnup fuel applications, the pellet rim effect, fission gas …
