The Micro Modular Reactor (MMR™) system is a 4th Generation small modular nuclear energy system that delivers safe, clean, and cost-effective electricity and heat to remote mines, industry, and communities.
The MMR™ reactor saves up to 50% of heat and electricity costs and eliminates 100% of carbon emissions.
The MMR™ reactor requires no refueling for its lifetime of 20 years. This ensures security at the site as the reactor is sealed, and simplifies operations, while reducing the costs associated with the diesel fuel supply typically used to power remote sites.
The MMR™ plant provides clean power and eliminates environmental risk. When the plant life is over, the nuclear fuel module will be removed and stored in a commissioned nuclear waste facility. A new module can be provided, or the site can be returned to greenfield.
The MMR™ plant has order of magnitude lower development costs compared to other SMRs and 4th generation reactor concepts.
MMR™ plant's small size and radical simplicity allow for factory manufacturing of all but the concrete foundations. Modules will be exported to licenced sites around the globe.
The cost of electricity and process heat are fixed for the lifetime of the plant. MMR™ plant costs and adjacent plant costs determine the price of the electricity and heat. The predictability of energy costs allows for more accurate mine feasibility analysis and reduces the risk profile for investors.
The MMR™ reactor uses safe FCM™ fuel, in a safety-focused design.
The MMR™ plant provides highly-flexible power that is 100% compliant to load demands at all times.
The MMR™ reactor is a high-temperature, gas-cooled nuclear reactor. This modern reactor uses proven technology, enhanced with proprietary, innovative safety features to deliver simple, scalable, and secure energy solutions.
The MMR™ system uses FCM™ fuel. Tiny grains of uranium are clad in layers of silicon carbide and encased in structural, fully-dense silicon carbide to provide the strongest possible barrier to the release of fission products. The fuel remains safe and undamaged under all operating and accident conditions.
The MMR™ nuclear reactor is only fueled once in its lifetime. There is no refueling required. No spent or spare fuel is stored at the reactor site.
The MMR™ reactor is a walk-away safe reactor. In the case of an accident, the MMR™ reactor cannot melt down, as all heat dissipates passively into the environment, no matter the scenario.
The MMR™ reactor is secure. The FCM™ fuel can be used only for power generation. The core is sealed, and the fuel cannot be re-purposed or re-processed for other uses.
The MMR™ plant is simple to operate, and its output is flexible. The use of molten-salt thermal storage can supply both electricity and/or process heat.
The MMR™ plant is completely modular and fully scalable. Each nuclear power unit is self-contained, and additional units can simply be added to the power plant as needed.
