Micro Modular Reactor
The Micro Modular Reactor® (MMR®) is a specific type of Small Modular Reactor (SMR) technology designed by Ultra Safe Nuclear Corporation.
The MMR includes a nuclear plant, which contains an MMR High Temperature Gas-Cooled Reactor that provides process heat to an adjacent plant via a molten salt heat exchange system. The MMR produces up to 45 MW (thermal) of process heat to generate electrical power and/or heat over an operating lifespan of up to 40 years.
The MMR is based on USNC’s proprietary Fully Ceramic Micro-encapsulated (FCM®) fuel technology which brings an unprecedented level of safety, as well as improved economics and reduced environmental impact for remote power applications.
USNC has been progressing the design of the MMR over the last several years. This includes completing the Phase 1 Vendor Design review with the Canadian Nuclear Safety Commission.
Advantages of MMR
Constructed and tested prior to arriving on site; assembled at site
Modules can be combined for different energy needs
Current project footprint is less than the size of two Olympic running tracks
One MMR unit could replace 1.2 billion litres of diesel
Key Features of the USNC-designed MMR
- Generates high quality heat for electricity and other applications
- Constructed and tested prior to arriving on site; assembled on site
- Minimal operations and maintenance requirements compared to traditional nuclear technology
- Scalable and modular – modules can be combined for different sites and energy needs
- The design is based on technology in use since the 1960s; similar designs in service in China and Japan; successful demonstrations in the United States and Germany
- Design-life of 40 years
