With solar and batteries getting cheaper and cheaper, is this still a topic? Or at least for the time being until that "cheaper" gets cheaper enough?

Yes, it does seem to still be a topic.

Although generally safe these reactors aren't totally safe.

I'm concerned lax physical security will allow miscreants to blow them up and spread nuclear materials over a wide area. The ensuing panic would totally destroy any goodwill nuclear power has gained over the last 20 years or so.

I'm also concerned these things will mostly be used by Big Tech for their A.I. data-centers playing the Good Samaritan with their claims of "Carbon Neutral Environmentally Friendly A.I."

They're all ridiculously fuel inefficient and we're going to have to figure out how to dispose of thousands or tens of thousands of these reactors. Aside from that one that starts pre buried, where the plan is to just leave a spent nuclear reactor buried in a hole. A cost that will almost certainly be externalized to the taxpayers.

The promise here is the rich fleecing the average citizen.

Getting downvoted wicked hard super fast. But how else are we supposed to see this? How else do we citizens of the world interpret this? The fuel efficiency is a fact. The nuclear clean up has been a problem every single time.

And the US is spending vastly more to make sure renewables and solar don't get built. https://www.washingtonpost.com/business/2026/08/27/how-wind-...

Well, gas and oil plants are actively emitting pollutants that kill thousands. And nuclear still is the safest energy sort available.

there is just one problem

like everything else with the current US administration

they deregulated nuclear safety

any other administration even Republican I'd be willing to listen to why

this administration will happily kill thousands or give them cancer if it means another million dollars in their pockets

there is only one kind of nuclear reactor that should be built anymore

and that is Thorium reactors, they "fail safe" (or at least safer)
