Will a natrium reactor be non-nuclear?
The Natrium reactor uses high-assay, low-enriched uranium (HALEU) metallic fuel. HALEU is a new class of nuclear fuel where the uranium-235 isotope content is above 5% but less than 20%. Many advanced reactors, including the Natrium technology, use HALEU because it improves reactor performance.

As mentioned in the introduction, the Natrium reactor can use not just U-235 as its fuel. This is a property of the neutrons used in the reactor. As a refresher, the water used in current commercial fission reactors acts as a moderator on the neutrons that are produced during a nuclear fission chain reaction, effectively slowing them down. This mak...
Before anyone is allowed to build or operate a nuclear plant in the US it has to go through the Nuclear Regulatory Commission (NRC). A panel of experts will analyze, comment on, and require changes to offered designs until they are confident that that all regulations are adhered to and all relevant questions answered. I covered this processin detai...
Perhaps most telling is that TerraPower isn’t the sole company seeking to commercialize a fast neutron reactor. In Russia, Rosatom along with nuclear fuel manufacturer TVEL have announced the start of construction of the BREST-OD-300lead-cooled reactor. Like the Natrium design, this is a Generation IV fast neutron reactor, but it uses lead as coola...
Where TerraPower’s Natrium reactor is different from the competition is that it focuses not so much on the traditional role of thermal plants which involves getting as much steam or equivalent to a turbine to generate electricity. Instead, the heat from the reactor’s core is led away using the sodium coolant and stored in multiple large, insulated ...
The world today grapples with the realization that the sooner we rid ourselves of fossil fuels, the better off we’ll be. Yet right now the overwhelming majority of our daily energy use for transport (even with electric vehicles) and such still comes from fossil sources. In US states like California, natural gas makes up the overwhelming majority of...
Jun 11, 2024 · The 345 MWe sodium-cooled fast reactor with a molten salt-based energy storage system - which can boost the system's output to 500 MW of power when needed, allowing it to integrate seamlessly with renewable resources - is being built near a retiring coal-fired plant.
Apr 2, 2024 · Natrium technology features a 345 MWe sodium-cooled fast reactor using high-assay low-enriched uranium fuel, with a molten salt-based energy storage system that can boost the system’s output to 500 MWe for more than five and a half hours when needed.
Jun 12, 2024 · Natrium is a TerraPower and GE-Hitachi technology and is one of two competitively-selected Advanced Reactor Demonstration Program (ARDP) projects supported by the US Department of Energy (DOE). The construction project is expected to cost up to $4bn, half funded by the ARDP.
