Superheated Water-Cooled Small Modular Underwater Reactor Concept

Nuclear Engineering and Technology, 2016
A novel fully passive small modular superheated water reactor (SWR) for underwater deployment is designed to produce 160 MWe with steam at 500ºC to increase the thermodynamic efficiency compared with standard light water reactors. The SWR design is based

Nuclear waste from small modular reactors

Proceedings of the National Academy of Sciences, 2022
Small modular reactors (SMRs; i.e., nuclear reactors that produce <300 MW elec each) have garnered attention because of claims of inherent safety features and reduced cost. However, remarkably few studies have analyzed the management and disposal of their nuclear waste streams.
