3. Once approved, the designs should be exempted fro EPA meddling and some reasonable level of lawsuit immunity...as in the construction can't be delayed decades by lawsuit after lawsuit.
What happens if someone discovers a flaw? So far every reactor design ever built has needed some modification afterwards, due to unforeseen issues. Seems like if there is no way to force companies to make those modifications, like a government agency telling them or affected citizens having the right to sue we will just end up with another Fukushima style accident.
4. Operators should undergo the same rigorous training as military nuke operators...subs, ships, etc. Not the same, but just as rigorous. We don't need fucking button pushes on the night shift. They have to understand the plant, the theory and they consequences of each action they take.
That's going to jack the cost up to military levels too then. Probably more, because unlike the military the nuclear plant operators would have to hire people on the commercial market and train them to a high level, and then pay them enough to retain them.
5. Parts should be manufactured in factories using standard methods and specifications. Parts should be interchangeable from site to site. Minimize customizations as much as possible.
There isn't really enough volume to justify that kind of mass production. Even if there were, many of the parts are specialist and have to last the lifetime of the plant, because once contaminated can't be easily replaced. In other words, it wouldn't bring costs down.
