Considering that the last civilian commercial license approval was in 1978 (IIRC) and the last construction in the 1990s, you could claim that nobody specializes in designing/building U.S. nuclear plants. Or you could claim that soon everybody will be doing it!
Westinghouse and GE have the most recent history and experience building nuclear propulsion systems for the U.S. Navy's submarine force and aircraft carriers. But even a CVN plant pales in comparison to those big honkin' commercial systems. My dad used to sell the secondary (steam) plants for Westinghouse reactors in the 1960s/70s, and left in 1977 with a lot of others when he saw where the industry was headed. An entire generation of design/construction knowledge, skill, and experience has been lost. In America, anyway.
When I was at my military training command before retiring, every nuclear submariner who wanted to continue being a nuke after Navy ended up at Exelon. There weren't many who wanted to continue being nukes, and they didn't all end up at Exelon, but it was over 80%.
It's worth pointing out that railroads, electricity, automobiles, and aircraft have all done wonderful things for civilization over the last century or so. The trouble is finding the 2-3 winners out of the hundreds of competitors, and even then the companies may consume far more capital than they return to their shareholders.
I thought investing in startup companies and small-cap stocks was courageous. But speaking as a 2nd-generation nuke, you're setting a new baseline for brave.
