MIT looked at this: > they consider things like the possibility of using a central facility to produce high-performance concrete parts for the plant, as we have shifted to doing for projects like bridge construction. But this concrete is often more expensive than materials poured on site, meaning the higher efficiency of the off-site production would have to more than offset that difference. The material's performance in the environment of a nuclear plant hasn't been tested, so it's not clear whether it's even a solution. https://arstechnica.com/science/2020/11/why-are-nuclear-plants-so-expensive-safetys-only-part-of-the-story/ https://arstechnica.com/science/2020/11/why-are-nuclear-plan...
