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 ... -
A control approach investigation of the Xe-100 plant to perform load following within the operational range of 100 - 25 - 100%
(Elsevier, 2018)This paper describes the Xe-100 plant load following analyses done in Flownex® thermal-fluid system simulation software for normal operation from 100 – 25 – 100% electrical power. The plant model encompasses all major ... -
Developing a steady state neutronic model for the PBR-250 HTR using Serpent 2.1.31
(North-West University (South Africa)., 2023-10)The PBR-250 reactor is a Generation-IV pebble bed high-temperature reactor with a rating of 250MWth and has the ability to produce electricity and process heat of up to 1000 °C. The most desirable feature of this reactor ... -
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 ... -
Using thorium to reduce the maximum fuel temperatures during depressurized loss of coolant accidents in a once-through-then-out (OTTO) PBMR DPP-400 core
(Taylor & Francis, 2017)This article presents the results for the PBMR-DPP-400, but for a once-through-then-out (OTTO) refueling scheme. An optimization attempt of the axial and radial power profiles is reported. The main aim was to reduce the ...
