Uranium is very common element. From your linked article :

> If one is willing to pay $300/kg for uranium, there is a vast quantity available in the ocean.[63] It is worth noting that since fuel cost only amounts to a small fraction of nuclear energy total cost per kWh, and raw uranium price also constitutes a small fraction of total fuel costs, such an increase on uranium prices wouldn't involve a very significant increase in the total cost per kWh produced.

So countries could build known and will tested reactor types to decarbonize world electricity production.

Further, given weather calamities due to global warming are detected, having dispatchable power less dependent on weather conditions is super important.

Eventually we would need to remove co2 from atmosphere as well, which is requires additional energy
