Small Modular Reactor based on NuScale with Thorium base

Brazilian Journal of Radiation Sciences
This study proposes a novel approach to enhance the NuScale Small Modular Reactor (SMR) by incorporating mixed uranium-thorium (U-Th) oxide fuel, thereby increasing U-233 production, improving fuel use, and reducing radioactive waste.

Strategic analysis on sizing of flooding valve for successful accident management of small modular reactor

Nuclear Engineering and Technology
In contrast to all-time flooded small modular reactor (SMR) systems, an in-kind flooding safety system (FSS) has been proposed as a passive safety system applicable to small modular reactors (SMRs) that adopt a metal containment vessel (MCV).

Analysis of small modular reactors

Thermal Science
Nuclear energy is currently the only technology that has potential to expand at a large scale and efficiently replace fossil-burning power plants. However, for this to happen particularly in the countries with undeveloped nuclear infrastructure, several important issues need to be addressed: financial, technological, and regulatory risks; nuclear ...
