Microreactors

A 5 MWt/2 MWe heat pipe reactor for "plug-and-go" power applications in remote installations and communities. The design is capable of rapid installation and shutdown and largely autonomous operation for 5 years without refueling. MegaPower is fueled by high-assay low enriched uranium oxide.

The X-battery is a gas-cooled pebble bed reactor fueled by high assay LEU fuel particles, capable of autonomous operation. The 10 MWt reactor is road-transportable and can be configured to provide combined heat and power.

SEALER is an 8 MWt/3 MWe lead-cooled fast reactor design for remote applications. SEALER is fueled by high-assay low enriched uranium oxide fuel, and operates for 10-30 years without on-site refueling. LeadCold developed a corrosion-resistant aluminum alloyed steel for use in the reactor.

Scalable, heat pipe-cooled reactor design producing combined heat and power of 0.2-25 MWe for decentralized and/or remote generation markets. The factory-built and assembled eVinci has inherent load following capabilities, rapid on-site installation potential, and infrequent refueling needs.

High-temperature, gas-cooled reactors with an closed-loop turbojet combustion system integrated into the core unit, eliminating balance of plant (BoP) components. Dry cooling supports the combined Brayton-organic Rankine power conversion cycle, and Holos Generators are capable of high-resolution, automatic load following. The core is formed through the neutronic coupling of independently subcritical, integral power modules, actively positioned on-site by an Automatic Module Positioning System (AMPS). Entire Holos Quad generators, capable of producing up to 13 MWe without fit inside a single ISO container; the larger Holos Titan generators, housed in 12 ISO containers would be capable of producing up to 81 MWe. A smaller Holos generator for rapid deployment applications (like emergency response) would be configured for air transport and for use as stand-alone electric islands without need for substation switchyard equipment.

A advanced, ultra-compact gas-cooled reactor with an energy conversion system and turbomachinery integrated into the core. Initial development efforts for the 3-50 MWe design are focused on remote locations, including space, and critical national security sites.

This simplified molten salt reactor is designed to reduce design and operational complexity: passive heat pipes eliminate the need for heat exchanger tubes and a naturally-circulating primary flow eliminates the need for pumps. Reactor system to be coupled with a small commercial gas turbine for electricity production of ~5 MWe.

Oklo's reactor is a liquid metal-cooled, fast spectrum reactor utilizing a metallic fuel. It is designed to be small, portable, and suitable for remote deployment.

LEADIR-PS100 is a 100 MWt/36MWe lead-cooled, TRISO-fueled, graphite-moderated pebble bed reactor.

These two light water-cooled and moderated reactors are smaller design variants of NuScale's larger SMR, in the 1-10 MWe size range. Both designs can operate for 10+ years without refueling. The single-unit NPM relies on commercially available uranium, while the reduced size NPM would rely on high-assay low enriched uranium. Both designs utilize highly automated control rooms, rely on natural circulation for cooling, and are capable of flexible electricity/heat generation for DOD facilities, towns, and industry.
