Those are intelligent points and I agree with them. Now we need test reactors to get the material data needed to prove those points to the NRC. And we still need the lithium-7 to 99.99% purity (they are doing it in China, but the COLEX process is not legal here and we don't have an alternate). Then we can work out all of the balance of plant issues, get the site licenses, build the units and turn them on. Which takes a dedicated energy policy with a lot of government commitment, and about 20-30 years, assuming some favorable economics from natural gas.
Like I said, I'm all for MSRs, but starting from where we are now we need a lot of time and money. They weren't ready when we built the light water reactors, and for them to be ready later, we need to start now,
