CFD and systems thermal-hydraulic analysis in the design and safety assessment of high-temperature reactors
(Woodhead Publishing, 2019)An overview is provided of the role of the various levels of CFD in the different stages of the design, analysis and evaluation of very-high-temperature reactor (VHTR) systems and molten salt reactor (MSR) systems. The ... -
CFD simulation of nuclear graphite oxidation
(North-West University, 2010)This study investigates the development of a strategy to simulate nuclear graphite oxidation with Computational Fluid Dynamics (CFD) to determine an estimate of graphite lost. The task was achieved by comparing the results ... -
An integrated thermal-hydraulic system CFD model of a prismatic block HTR core using Flownex
(North-West University (South Africa), Potchefstroom Campus, 2019)The active core of a prismatic high temperature reactor (HTR) consists of standard fuel, reserve shutdown and control blocks which must be maintained within a safe operating envelope. The fuel blocks are coupled to the ... -
A neutronic model of the PMR200 prismatic modular reactor using MCNP5
(North-West University (South Africa) , Potchefstroom Campus, 2016)The PMR200 reactor is a prismatic modular High Temperature Reactor. The High Temperature Reactor is a near term Generation IV reactor with the capability of producing electricity, and its high outlet temperature ... -
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 ...
