Reactors

First Light Fusion's approach involves the assymmetric implosion of deuterium-tritium fuel, resulting in a unique plasma geometry.

The Westinghouse LFR is a lead-cooled, fast spectrum reactor with an output in the 500 MWe range.

Helion is developing a 50 MWe-scale field-reversed configuration fusion system in which deuterium-helium 3 plasmas are injected into opposite sides of a linear reaction chamber and accelerated into a "burn chamber" at over 100 million mph, where strong magnetic fields compress the merged plasmas to fusion conditions. Unlike its leading private fusion vendor competitors, Helion is pursuing direct energy conversion for its first-of-a-kind "Fusion Engines".

This spheromak-type system employs proprietary imposed-dynamo current drive (IDCD) to sustain compact, steady-state plasmas.

The HyperJet Fusion reactor is spherically-shaped magneto-inertial confinement device with a shot rate of approximately 1 Hz. Fusion conditions are achieved within the magnetized tritium-deuterium plasma fuel through the implosion of a high-Z plasma liner.

A form of alternative magneto-inertial fusion utilizing deuterium-tritium fuel. Described by the company as "beam-target" fusion, the proposed technology involves a solid Lithium BoroTritide target and magnetic focusing lenses for the deuterium and helium-3 ion beam.

HTR-PM is a helium-cooled, graphite-moderated thermal spectrum reactor with a pebble bed core. With 8.5% enriched uranium-based TRISO fuel, this reactor has a capacity of 250 MWt/105 MWe. A two-unit demonstration plant is in the final stages of construction, and is expected to come online this year.

SmAHTR is a fluoride salt-cooled, graphite moderated molten salt reactor that utilizes solid, static, LEU-based TRISO fuel with a capacity of 125 MWt/50MWe. All primary components are integrated into a single vessel. A design variant for hydrogen production applications, the SmAHTR-CTC (carbonate thermochemical cycle), is also under development.

The FHR is a fluoride-based salts-cooled, high-temperature thermal spectrum reactor with solid, pebble-type TRISO uranium fuel. Its "Nuclear Air Combined Cycle" system enables highly responsive electricity generation through co-firing with natural gas or hydrogen.
