ALMRs

ALMRs, or Advanced Light Water Reactors, represent a generation of nuclear reactor designs that aim to improve upon the safety, efficiency, and economic viability of traditional Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs). These designs are based on the well-established light water coolant technology but incorporate significant innovations. Key features often include passive safety systems that rely on natural forces like gravity and convection rather than active components or external power sources to manage reactor cooling and shutdown. This enhances safety by reducing the potential for human error or equipment malfunction to lead to accidents. Many ALMR designs also focus on improved fuel utilization and waste reduction. Some concepts incorporate advanced fuel cycles or in-reactor technologies to burn long-lived actinides, potentially reducing the volume and radiotoxicity of spent nuclear fuel. The goal is to offer a more sustainable and secure nuclear power option. ALMRs are still largely in the development and design phases, with several countries and private companies pursuing different technological approaches. Regulatory approval and commercial deployment remain ongoing processes.
