Comparison of heat transfer models at the pebble, gas and reflector interface in the PBMR
(North-West University, 2010)It is a great challenge in the design of the PBMR to accurately predict gas flow and heat transfer in the reactor. Understanding the heat transfer at the core-reflector interface in particular is a very important aspect ... -
Steam generator thermal-fluid simulation using a coupled Flownex and RELAP5/mod4.0 approach
(North-West University (South Africa) , Potchefstroom Campus, 2015)The steam generator (SG) is one of the biggest structural components in a nuclear power plant (NPP), and can in many respects be seen as the heart of the system. It functions as a heat exchanger between the primary and ... -
Thermal fluid network model for a prismatic block in a gas-cooled reactor using FLOWNEX
(2015)Very High Temperature Reactors are complex reactors and various system codes have been developed to design different aspects such as neutronics, thermal hydraulics etc. Flownex is one of the system codes and it has been ... -
Thermal–fluid simulation of nuclear steam generator performance using Flownex and RELAP5/mod3.4
(North-West University, 2012)The steam generator plays a primary role in the safety and performance of a pressurized water reactor nuclear power plant. The cost to utilities is in the order of millions of Rands a year as a direct result of damage to ... -
Uncertainty and sensitivity analysis of a materials test reactor
(2013)This study was based on the uncertainty and sensitivity analysis of a generic 10 MW Materials Test Reactor (MTR). In this study an uncertainty and sensitivity analysis methodology called code scaling applicability and ...
