3D Reactor Physics Modelling Of Reduced-Moderation Water Reactor (RMWR) Fuel
The Reduced-Moderation Water Reactor (RMWR) is an innovative water-cooled reactor with some of the characteristics of a fast neutron reactor, which can achieve a high conversion ratio of more than 1.0 and a negative void reactivity coefficient. The conception of RMWR is built on established Boiling …

Core design and reactor physics of a breed and burn gas-cooled fast reactor
… has focused on the design of a Gas-cooled Fast Reactor (GFR) operating in a Breed and Burnm (B&B) fuel cycle mode. B&B refers to a once-through fuel cycle where low enriched uranium (less than 5 w/o 235U in U) subcritical assemblies are loaded into the core in equilibrium, yet in-situ plutonium …

Development of a microchannel reactor model
… an on-board fuel processing system. Microchannel reactors have reduced mass and heat transfer limitations and are able to exploit fast intrinsic kinetics. Also, their high surface area to volume ratio reduces their size for a constant throughput, increasing their potential for miniaturised …

Meta-analysis of Tokamak reactor designs
… fusion using tokamaks has yielded many published reactor designs. This study performs the first meta-analysis of tokamak reactor designs in an attempt to unveil new understanding not available in the traditional bottom-up method of looking at each design individually. Forty tokamak designs …

Critical assessment of thorium reactor technology
Thorium-based fuels for nuclear reactors are being considered for use with current and future designs in both large and small-scale energy production. Thorium-232 is as abundant on Earth as lead, far more common than all isotopes of uranium, leading to its greatly reduced cost. Thorium itself …

The design of a reduced diameter Pebble Bed Modular Reactor for reactor pressure vessel transport by railcar
Many desirable locations for Pebble Bed Modular Reactors are currently out of consideration as construction sites for current designs due to limitations on the mode of transportation for large RPVs. In particular, the PBMR-400 design developed by PBMR Pty of South Africa uses an RPV with an outer …
