Enriched uranium

But you want about, for a light water reactor, you need about 5%.

That's LEU, low enriched uranium is LEU.

Enrichment level is up to 5%.

and but you can enrich it further if you enrich it between five and ten percent is known as leu plus and there is also this new um fuel requirement for advanced reactors and that is halo high assay low and rich uranium that is all the way to 20 or they tend to stay just below this this credit that that mass and this is so 19.75 is considered a halo fuel for advanced reactors such as small modular reactors and micro reactors.

It's been demonstrated in the late 80s and the early 90s.

It showed that it can enrich uranium in a single step.

It takes us from natural uranium all the way to LEU, which is up to 5% in one stage, which is huge.

If you compare that to centrifuges, they need energy.
