Off topic: Could someone explain to the others what percentage of the uranium contained in the fuel is actually "burned". The truth is that fuel is used quite inefficiently than in modern nuclear weapon...

Doesn't matter and doesn't matter though. Uranium is more common than tin in the Earth's Crust. https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth's_crust

And one-kilogram of Uranium-235 contains as much energy as 100-tons of coal.

Yes, we only burn like 1% of it, but even with a 99% inefficiency ratio compared to a nuclear bomb. But "tiny number x 100" is still "tiny number". Uranium is like 100-kilograms of raw material mined vs 100,000-kilograms of other energy sources.

Practically nothing nuclear Fuel is made up of loads of different isotopes of uranium and sometimes some plutonium

after their stay in the reactor about 50% of the p239 and u235 will be used up.
but that only makes up a small percentage of the mox pellets

People also forget that the fusion reaction obtained recently came from the Lawrence Livermore National Laboratory. Fusion modeling and subsequent calculations takes a lot of resources to calculate in a timely manner.

Remarks saying we don't need supercomputers at weapons labs are easy, but like the fusion calculations, applications to be used on these exascale machines are much more complex and have multiple use cases outside of the military: https://www.exascaleproject.org/research-group/national-security/.

Calculations for scenarios like re-entry to the Earth's atmosphere can be applied to designing more efficient vehicle geometry that dissipates heat more effectively or wastes less material replacing burnt tiles.

Nuclear is clean as soon as you are not one of countries that needs to store nuclear waste for centuries...

It's not quite what you think it is...
