The president's executive order requires what appears to be a completely overhaul of the NRC by November of next year. I guess we'll see how that goes.
Solar, wind, and battery tech are getting so cheap so fast, it's hard to know whether this will be enough to make nuclear economical.
Perhaps they'd like another Three Mile Island, Chernobyl, or Fukushima instead.
It's ignorant people who complain about "regulations" as a monolithic, monochromatic evil MacGuffin that exist merely to stop progress rather than encompassing health and safety regulations written in blood and graves.
I remember my coworker who had to destructively flame test half of the wire nuts he sold to a nuclear energy concern by verifying they self-extinguished within X seconds. Rigor might be expensive, but lives, health, and peace of mind are worth more even if techbros and billionaires don't think so.
If the NRC went over the regulations with a bit of common sense, reactors would be dramatically less expensive.
