Analysis of specific design aspects of a thorium-uranium fuelled European Pressurised Reactor
(North-West University (South Africa) , Potchefstroom Campus, 2017)The global nuclear industry is an established industry, however, should governments decide to move forward with more nuclear power. Enough resources are required to succeed in this endeavour of generating the electric power ... -
Different techniques for reducing DLOFC fuel temperatures in a PBMR-DPP-400 core
(Elsevier, 2018)This article addresses 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 ... -
The feasibility of extraction of thorium and rare earths from monazite through a thermal plasma and a chemical treatment process
(North-West University (South Africa) , Potchefstroom Campus, 2017)Monazite is a chemically inert, rare earth phosphate mineral, which is difficult to process using conventional chemical digestive techniques. Monazite contains important commercial sources of thorium and lanthanides. The ... -
Feasibility of thorium extraction from a solid monazite matrix utilizing supercritical CO2 with TBP and HFA as chelates
(2014)With current energy demands globally and locally, nuclear energy remains one of the top competitors for cleaner and sustainable energy. The nuclear industry requires more inherent safety and proliferation resistance in ... -
A heterogeneous Thorium-based fuel design for a PWR aimed at increasing fuel cycle length
(2015)A new heterogeneous Thorium based fuel design has been proposed for Pressurised Water Reactors in order to increase fuel cycle lengths. This design incorporates ThO2 pellets which have been included between UO2 fuel pellets ... -
The influence of thorium, uranium and plutonium fuel mixture composition on the reactivity coefficients of pressurised water reactors
(North-West University (South Africa), 2019)Temperature reactivity coefficients of a PWR (Pressurized Water Reactor) containing three fuel mixture compositions of uranium, thorium and plutonium in the form of UO2 with Low Enriched Uranium,Th-UO2 with Low Enriched ... -
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 ... -
Optimisation criteria of a Rankine steam cycle powered by thorium HTR
(2014)HOLCIM has various cement production plants across India. These plants struggle to produce the projected amount of cement due to electricity shortages. Although coal is abundant in India, the production thereof is in ... -
Thorium–based fuel cycles : saving uranium in a 200 MWth pebble bed high temperature reactor
(North-West University, 2010)The predominant nuclear fuel used globally at present is uranium which is a finite resource. Thorium has been identified as an alternative nuclear fuel source that can be utilized in almost all existing uranium–based ... -
Transfer Rates of 238U and 232Th for E. globulus, A. mearnsii, H. filipendula and Hazardous Effects of the Usage of Medicinal Plants From Around Gold Mine Dump Environs
(MDPI, 2015)Medicinal plant consumption can be a source of human exposure to radioactive elements such as 238U and 232Th, which can lead to internal radiation doses. The uptake of 238U and 232Th from soils to the leaf samples of three ...
