Reactors

GTHTR300 is a helium-cooled, graphite-moderated thermal spectrum, prismatic high-temperature gas-cooled reactor with 14% enriched uranium-based TRISO fuel with flexible industrial/electricity generation applications. It provides a maximum of 600 MWt power and 100-300 MWe, depending on its application.

ASTRID is a sodium-cooled, pool-type fast spectrum reactor fueled by mixed oxide (MOX) fuel with a capacity of 1500 MWt/600 MWe. As an industrial demonstration reactor, ASTRID will be used to optimize the design of future commercial reactors under the umbrella of the Generation IV forum (GIF).

As part of the Heavy Liquid Metal Coolant (HLMC) research initiative, Argonne National Laboratory (ANL) has developed multiple multiple advanced reactor technologies, including the Secure Transportable Autonomous Reactor with Liquid Metal (STAR-LM) and the Small Secure Transportable Autonomous Reactor (SSTAR). SUPERSTAR, a lead-cooled, pool-type fast spectrum reactor is the most recent HLMC research initiative design. It has a capacity of 300 MWt/120 MWe is designed for electricity generation on the export market.

Fueled by plutonium and thorium, this pressure tube-type SCWR operates in the thermal neutron spectrum at a high pressure of 25 MPa. It is moderated by heavy water and cooled by supercritical light water, utilizes a direct steam cycle power conversion system, and has a capacity of 2540 MWt/1200 MWe. AECL is also developing a small, modular version of its SCWR called the Supersafe Reactor (SSR).

Building an optimized in-space transportation network powered by small modular reactors, beginning with nuclear-powered space tugs for precision orbital insertion of spacecraft and cargo hauling.

The SSR is a zirconium and sodium fluoride salts-cooled, graphite-moderated thermal spectrum molten salt reactor. 8 37.5 MWe modules form a standard 750 MWt/300MWe unit. The static form of the liquid fuel salt eliminates many of the technical hurdles associated with mobile, liquid fuels typical to molten salt reactors; fuel assemblies are designed for compatibility with existing IAEA Safeguard procedures

The MCFR is a chloride salt-cooled, liquid-fueled fast spectrum molten salt reactor operating on a U-Pu fuel cycle. This breed-and-burn concept utilizes depleted or unenriched (natural) uranium as makeup fuel.

The IMSR is a fluoride salt-cooled, graphite-moderated, liquid-fueled thermal spectrum reactor based heavily on Oak Ridge National Labs' Denatured Molten Salt Reactor. The 400 MWt/190MWe reactor is designed to operate for 7 years with online refueling, utilizing 5% (or lower) enriched uranium as both startup and makeup fuel. The integral reactor vessel, which contains all primary systems, doubles as intermediate-term containment and is designed to remained sealed during operation.

CFS plans to engineer Rare-Earth Barium Copper Oxide (REBCO), a new superconductor technology, into high-field magnets, which enables much smaller tokamak fusion systems.

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.
