The 'advanced' nuclear industry has dozens of big players and is raising money like crazy. Everyone wants to mess around with exotic fuel and coolants. But no one cares about the real workhorse reactors anymore like ABWRs, APR-1400, etc. We should be more focused on those imho.

Came here to say that. From what I understand, a lot of nuclear welders retired and because very few projects happened in the past couple of decades, their expertise was not transfered. It is a shame.
