The technological breakthrough may be possible. As other people mentioned here, it looks like the problem now is that the experience of building nuclear reactors was lost, so we are in a Catch-22 situation right now: if you want to build experience you need to just build reactors, but they are not economically viable without experienced builders. The problem is that all current reactors are of the 1 GW size. For the last few decades the world has been building about 1 or 2 per year outside of China. The solution is small nuclear reactors. For very large machines there is a dis-economy of scales. It was more expensive to build a Saturn V rocket than to build 20 rockets that are 20 times smaller each. In fact it was 3 times more expensive (about $180MM/ launch for Saturn V vs $3MM for Titan II) Similarly, it's quite likely that it will be much cheaper to build 20 reactors of 50 MW each than it is to build a 1 GW reactor. And this is exactly what small nuclear reactors hope to achieve. For example NuScale estimates it will cost them $3 BN to build a 600 MW power plant [1] using small modular reactors.
