This is for America, I don't have anything to hand for Europe https://www.greentechmedia.com/articles/read/study-transmission-is-the-key-to-a-low-cost-decarbonized-u.s-grid https://www.greentechmedia.com/articles/read/study-transmiss... Also, this is with technology we have right now that we know works. The problem with SMRs is they have always been 5-10 years away from being ready. We have to plan based on what we know now, not make pipe dreams based on technology we would like to have and which may never pan out.

> We have to plan based on what we know now, not make pipe dreams based on technology we would like to have and which may never pan out. Same deal with solving for reliability with renewables. We should invest in solving both problems. Moreover, I suspect that "always 5-10 years away from being ready" has a lot more to do with regulators than feasibility.

The us navy has been building SMRs for decades. Their reactors don't need to generally be refueled either since they use higher grade fuels and burn them in place for 30+ years. So, there are differences but mostly these aren't cutting edge designs, they are 50 year old concepts that have been studied and understood to death. Yes there are differences, but the fact that the NRC can't certify a reactor class that the navy builds (without interference from the NRC) is itself a problem.

I have a hard time seeing nuclear weapons grade fissile materials spread around in every SMR in every town around the world as a feasible solution.
