Yes the boiling water nuclear plants designed in the 1950s are massive, complicated, and expensive to build. I don't think anyone is suggesting that we start building more of those.
Got any evidence that nobody wants to build the same style of big reactors we currently have in our fleet? Because more than half of the people that I talk to that support nuclear want exactly that. There are two reasons that I hear in support of this: 1) we did it before, so people think it's a good idea still, and 2) that's the only type of reactor that we have designed and could start deploying today. It's the type of reactor that Rosatom will build, it's the type of reactor that China is building.
Other reactor types are far far far out on the design schedule, and more speculative in terms of technological success than any of the many new types of battery chemistries that have been announced this year.
