It is hideously expensive. Don't know how these guys are gonna do it. I remember talking with a prominent VC who had a division in the energy space. They got a few nuclear startup pitches. Always, it was 'we need 100 mil... and 50 of that is going to the gov't for licensing'. If these guys have figured out a way around this. All the power to them.
and $50Mill is probably not going to pay for building a test reactor and all the research that will need to be done before that plus you will need some decent HPC grunt to do you CFD modeling then real world physical models (1:1 and over scale is not cheap) to prove the math works.
