Consistent multi-scale uncertainty quantification methodology for multi-physics modelling of prismatic HTGRs
(North-West University (South Africa), 2020)As one of the Generation-IV advanced reactor types, High Temperature Gas-Cooled Reactors (HTGRs) can provide high-quality heat to industrial processes, in addition to saleable and inherently safe power operation. In the ... -
Further development of methodology to model TRISO fuel and BISO absorber particles and related uncertainty quantification using SCALE 6
(Taylor & Francis, 2019)In the 350 MW Modular High Temperature Gas-Cooled Reactor (MHTGR-350), not only is the fuel double heterogeneous but so are the lumped burnable poisons (LBPs). The LBPs are composed of Bi-Structural Isotropic (BISO) particles ... -
The influence of thorium on the temperature reactivity coefficient in a 400 MWth pebble bed high temperature plutonium incinerator reactor
(2012)Social and environmental justice for a growing and developing global population requires significant increases in energy use. A possible means of contributing to this energy increase is to incinerate plutonium from spent ... -
Neutron poison distribution in the central reflector to reduce the DLOFC temperature of a Th-LEU fueled OTTO PBMR DPP-400 core
(Taylor & Francis, 2018)In a previous study using a mixture of thorium and 20 a/o% LEU at 16 gram per fuel sphere heavy metal loading and adjusting the effective fuel enrichment to produce the same amount of cumulative energy per fuel sphere as ... -
Uncertainty and sensitivity analysis of aspects of the neutronics of a prismatic block-type HTGR
(2019)The International Atomic Energy Agency (IAEA) Coordinated Research Project (CRP) on High Temperature Gas-cooled Reactors (HTGR) Uncertainty Analysis in Modelling (UAM) has been established aiming to study uncertainty ... -
Using thorium to decrease maximum DLOFC temperatures and increase total power output in Pebble-Bed High Temperature Reactors
(North-West University, 2018)This is a study on the topic of modifying the fuel cycles of Pebble-Bed Reactors in order to reduce their maximum fuel temperatures during Depressurised Loss of Forced Coolant (DLOFC) accidents, in order to prevent ... -
Using thorium to reduce the maximum fuel temperatures during depressurized loss of coolant accidents in a once-through-then-out (OTTO) PBMR DPP-400 core
(Taylor & Francis, 2017)This article presents the results for the PBMR-DPP-400, but for a once-through-then-out (OTTO) refueling scheme. An optimization attempt of the axial and radial power profiles is reported. The main aim was to reduce the ... -
Utilization of heat from a nuclear high temperature cooled modulator reactor in a crude oil refinery : techno-economic feasibility analysis
(2014)This research project will investigate the potential business case and technical feasibility of using nuclear generated heat in a crude oil refinery located some distance away. The key design element is an energy ...
