Effect of reactor vessel cooling insulation and reflector heat pipes on the temperatures of a pebble-bed reactor using a system CFD approach

Du Toit, C.G.; Van Antwerpen, H.J. (Elsevier, 2020)

This study investigates firstly, the effects of varying insulation thickness and flow path width between the core barrel and RCCS-concrete pressure vessel of an upward-flow helium-cooled pebble bed HTGR. The effects on ...
Investigation of 1D system CFD and 3D CFD numerical methodology applied to an experimental facility

Niemand, P.F.; Du Toit, C.G. (SAAM, 2018)

The fourth generation gas-cooled nuclear reactor designs provide a promising prospect for energy and process heat generation. The designs` cycles have high thermal efficiencies, require relatively little fuel and are safe ...
Modelling of convection heat transfer in the SNU Riser Heat transfer Experimental Facility (RHEF)

Du Toit, C.G.; Shin, D.H.; Park, G.C. (SAAM, 2018)

The Reactor Cavity Cooling System (RCCS) of a High Temperature Gas-cooled Reactor (HGTR) plays an important role in ensuring the integrity of the HTGR during normal operating and accident conditions. The performance of ...
