> we're at least a generation away from any new installations much less meaningful adoption within the grid.

That's just not the case, if sanity prevails at all. We could have much safer Gen IV plants online within 10 years easily. It just takes the will to do it.

And how long before the regulations change to allow it? And how much longer before local zoning allows it? And how much before a utility clears all the build and commissioning hurdles and plant trials? And how long before sufficient quantities are in place to supplant natural gas? I hardly think one should say “if sanity prevails” and “easily” when talking about reviving nuclear. We’ll be on mars before we see meaningful levels of nuclear power.

Until there is a nuclear process that does not produce waste (both spent fuel and the reactor components) that must be stored for tens of thousands of years it is irresponsible to build them.

AFAICT Gen IV is basically the same technology in a brighter wrapper.

There is some hope thorium energy amplifiers (? correct term?) might fit the bill, but I do not know of one that has been built.

Also as the English are finding it is a very expensive way to generate electricity.

We can do better.

Thorium may be a solution. There are also molten salt reactors that are very promising. Unfortunately, when you look at nuclear energy policy, the two people most likely to be willing/capable to create positive policies supporting these new technologies also seem to be against any nuclear development at all [1]. They are talking in terms of 2030 timelines for elimination of nuclear - thus, my comment that we can't expect any new substantial contributions in a 'generation.' If US policy makers are already making plans that go out into the 2030s that do not include nuclear, it will take at least as long to bring it back to the table. How would one even build a test reactor in the US if the energy policies disallow it at commercial scale?
