The core conversion studies of the Ghana Research Reactor Core started in 2006 and with the objective of designing an LEU core with similar operational capabilities as the original HEU core and with acceptable safety margins under both normal and accident conditions. Steadystate studies for converting the Ghana MNSR facility from HEU to LEU core have been performed using the PLTEMP/ANL V4.1 cod...

The controlled self-assembly of polymer-stabilized quantum dots (QDs) into mesoscale aqueous spherical assemblies termed quantum dot compound micelles (QDCMs) using a two-phase gas-segmented microfluidic reactor is described. Self-assembly is initiated by the fast mixing of water (approximately 1 s) with a blend solution of polystyrene-coated QDs and amphiphilic polystyrene-block-poly(acrylic a...

This study presents an optimal design of the coolant system a non-refueling full-life small reactor by analyzing space-integrated geometrical and electromagnetic variables extra vessel pump (EVEMP) for circulation lead–bismuth eutectic (LBE) coolant. The EVEMP is ideal alternative to thermal-hydraulic micro reactors as it possesses no internal structures, such impellors or sealing transportatio...

The FM01-LC is a laboratory-scale, electrochemical filter-press cell with a projected electrode area of 64 cm and a rectangular electrolyte flow channel which was originally based on the larger FM21-SP electrolyser of 2100 cm projected electrode area designed for the chlor-alkali industry then diversified to other applications. Many laboratories and industries have utilised this type of control...

This study investigates use of solar thermochemical processing of clean fuels using biomass products (in particular CH4, H2O). To address technological feasibility of a microchannel-based solar receiver/reactor, a combined numerical and experimental study of methane-steam reforming is carried out on a single microchannel with Palladium-deposited channel walls and heat input to facilitate endoth...

Simulation of turbulence boiling, generation of vapour and predication of its behaviour are still subject to debate in the two-phase flow area and they receive a high level of worldwide attention. In this study, a new arrangement of the three dimensional governing equations for turbulence two-phase flow with heat and mass transfer are derived by using ensemble averaging two-fluid model and ...

Abstract This work presents an overview of issues for the modeling laminar flows in monolith catalysts. Both 0-D and 3-D models are evaluated a parallel channel structured honeycomb catalyst (PC-HC), gyroid printed (G-3D). At homogeneous reactor level, analysis is focused on effect bulk porosity, as well model choice to represent Nusselt number effects. Results show better suitability long tube...
