China is the leading manufacture of conventional and advanced reactors. They also produce more TRISO fuel than the rest of the world combined. We have to do better. We're doing our part to re-industrialize 🇺🇸 starting with our TRISO nuclear fuel factory.

@BowTiedAstrnaut Yep. They’ve been producing TRISO at industrial scale for years now. Some major differences: 1) we use prismatic cores not pebble beds; 2) we use Silicon carbide as filler material between the triso particles.

@NelsonDaleSmith At market price, the mg of uranium would be about $12.

@NelsonDaleSmith A TRISO particle contains 1 mg of enriched Uranium… In a typical reactor, you could extract about 1 kW for 150 days (150kW day). In practice, it will be run at 50-300 W for longer periods of time

@NelsonDaleSmith Diameter and thickness of the ceramic layers is part of the design and can vary from 600 microns to 900 microns

We can make it all. Visit

We sort millions, and soon billions, of these sesame sized nuclear TRISO particles.

Megawatt-class fission power systems can provide the energy for key architecture building blocks, such as propellant production, growing food, and in-space manufacturing that are not easily provided by solar on the megawatt level.

We want to travel further and faster, grow and expand, live longer and better. Energy is the ultimate constraint on our human ambitions. We are loosening that constraint with advanced nuclear reactors and fuels providing zero-carbon power and heat.

Bouncing UO2 particles around inside a hot furnace. This is how we coat 10s of micron thick layers of ceramics on our TRISO particles.

Fission power holds great promise for providing the 24/7 Megawatt-class power needed for humanity to live, work in orbit, and the lunar surface.

@clumma Air cooling on mars is not easy

@Phrankensteyn Here’s the paper. You should come to the NETS conference next year.

@jetpen Fuel utilization is a secondary problem to cost and just getting reactors built.

@Laythe_li_suwi @ChefWeeeee The yield is quite high, but the few particles that are removed can be processed to recover the fresh fuel sphere at the center of the particle

@Laythe_li_suwi @ChefWeeeee Wrong diameter, not spherical enough

@z15design lol we’d probably get more DOE gov funding if we did that
