Too items I would modify.
One 4 Gen technology is not using spent nuclear fuel.
Two, batteries are not a bad thing. Combined with steady state nuclear, they can produce power than used during the night and provide needed power during the heat of the day spikes. Nuclear does not ramp up and down well.
Nukes good, batteries okay. The batteries allow us to use more nukes.
I am not pushing it. I am putting it out for discussion.
Gov. Rick Perry has the DOE apparently moving Gen IV along.
Gen IV Nuclear is a political compromise, between Green New Deal (GND) types and Climate Change Deniers.
You might say: "Yes but GND is not necessary, since the Climate Change Deniers are correct."
The alternative needs to be on the table.
In the longer run, billions of middle-class Chinese and Indians Brazilians, Russians etc. will want energy.
By developing nuclear technology, the US could coninue to be the "energy solutions" technology powerhouse that we have been so far.
