The whole way the regulatory system was changed basically made making new designs impossible. In the 60s literally 100s of nuclear reactors were build and tested. Many with pretty small budget, and amazing innovation were achieved. But then the government started to turn against nuclear, defended all but a few projects, made access to nuclear material basically impossible, put in a regulatory system that made it 99.9999999% impossible for any new reactor to be ever licensed. I do not think it is to late, nuclear is still the most efficient method based on a first principle analysis. The question is just can we develop a commercial product.
