A comparison of catalyst application techniques for membrane electrode assemblies in SO2 depolarized electrolysers
(North-West University, 2011)Hydrogen production via the electrolysis of water has gained a lot of attention in the last couple of years. Research related to electrolysers is mostly aimed towards decreasing the noble–metal catalyst content. In this ... -
The feasibility and application of multi–layer vacuum insulation for cryogenic hydrogen storage
(North-West University, 2011)A need was identified to test multi–layer vacuum super insulation (MLVSI) used in cryogenic applications for hydrogen storage. The study focuses on the application of commercially available MLVSI to a locally patented ... -
The feasibility of the manufacturing of a printed circuit type heat exchanger produced from graphite
(North-West University, 2009)The development of high temperature heat exchangers will play a vital part in the success of High Temperature Nuclear Reactors (HTRs). Manufacturing such heat exchangers from metals is becoming increasingly difficult as ... -
Integration of cast simulated mechanical properties into FEA for improved tensile strength evaluation of ductile iron gate valve bodies
(North-West University (South Africa) , Potchefstroom Campus, 2017)Valve production is one of the most cost competitive industries worldwide, and South African valve manufacturers face strong competition, predominantly from China. Simulation software can be used to engineering lighter, ... -
An investigation of the manufacturability of tungsten-copper for use in a compact recuperator
(North-West University, 2008)A substantial raise in recuperator effectiveness has been established in the past by improving the fabricating and joining configurations regarding the manufacturing of compact recuperators. Further advancement of ... -
The machining process of Zircaloy-4 nuclear fuel rod end-caps
(North-West University (South Africa), 2021)Zirconium alloy 4 (Zry-4) is one of the most used materials inside a water-cooled reactor’s fuel assembly (Schemel, 1977). The reasons for the extensive use of this material inside the fuel assembly, are its high corrosion ... -
Methanol quality and its effects on the fuel-cell reformer off-gas composition
(North-West University (South Africa), 2019)Previous research articles that deal with methanol-steam reforming with Cu/ZnO/Al?O? catalyst do not take into account the quality of methanol used and the effect that it would have on catalyst performance and the off-gas ... -
Modelling the resin infusion under flexible tooling process : a physical and genetic approach
(North-West University, 2006)Resin Infusion under Flexible Tooling (RIFT) is a process by which resin is infused through the fibres through the application of a vacuum. Only a one-sided mould is used and the other side is covered with a flexible bag. ... -
Operational optimization of the Necsa SAFARI-1 neutron diffraction strain scanner
(North-West University (South Africa) , Potchefstroom Campus, 2017)This thesis reports on research performed by D. Marais during the period February 2012 to November 2016 at the South African Nuclear Energy Corporation (Necsa) SOC Limited. During this period, the Radiation Science division ... -
Relationship between the natural frequencies and fatigue life of NGB–18 graphite
(North-West University, 2010)NBG–18 graphite is developed by SGL Carbon for the Pebble Bed Modular Reactor Company (PBMR), and is used as the preferred material for the internal graphite core structures of a high–temperature gas–cooled nuclear reactor ... -
Simulation of the deformation of a stope support design
(2014)Supported stope mining is one of the most common types of mining in the modern day gold mining industry. The excavated regions, where ore is extracted, are supported with a combination of roof-bolting, timber packs, ... -
The solution processing and stoichiometry of ZrC
(North-West University (South Africa), 2020)In the aftermath of the incident at Fukushima Daiichi, evaluation of alternative Accident-Tolerant Fuel (ATF) was initiated. The purpose of ATF systems is to achieve greater safety margins by delaying the initiation of ... -
The synthesis and use of nitrogen derived titanates for the adsorption of uranium from aqueous waste streams
(North-West University (South Africa), 2020)The synthesis and use of layered hydrazinium and ammonium titanate as an adsorbent for uranium in a nitric acid solution was investigated. Several different titanate synthesis methods were identified from literature. Three ... -
Upscaling of a sulphur dioxide depolarized electrolyzer
(North-West University, 2012)In the last couple of years there has been a great need for finding alternative, cleaner burning fuel sources. This search has led to the development of various hydrogen technologies. The reason for this is that when burnt, ...
