Somehow I doubt the russians are supplying fuel for the SMRs in Nato nuclear submarines.

Naval reactors run on HEU because they need to be compact, have high power density, and rapidly change power level because they're being used for propulsion, and that's the most practical way to meet the requirements. We've spent decades trying to phase out use of HEU in any reactors where it isn't absolutely necessary to meet requirements (e.g. adapting research reactors to use LEU or MOx fuel, and shutting down older power reactors that used HEU). There's no way the proposed commercial SMRs will be allo

Just don't confuse HEU, Highly-Enriched Uranium, with HALEU, High-Assay Low-Enriched Uranium.
They are different things. HEU is restricted to military systems because in principle it could be diverted for use in making a crude, but functional, nuclear bomb. HALEU would require isotope separation, which is a difficult process and easier to detect.
It is HALEU, not HEU, that is being proposed for the small plants.

Yes, but look at the comment I replied to [slashdot.org]:

They're the ones saying that naval reactors need the same fuel as these proposed SMRs. I was pointing out that naval reactors use different fuel.
