At least one the Navy Nuke side, they need to survive what colleges count as 50 to 92 credits in a year and a half. So considerable levels of training.
Anything govt. Nuclear is also going to have "interesting" relationships with procedures. Essentially planning them out, proving them as functional, and being pretrained think about current conditions compared what the procedure thinks is correct. Also trained to analyze when to step into a casualty or recovery procedure properly.
Those still seem to be projects years away from completion (and they also have projects for fusion powered data centers - which are 30 years away, I guess?), yet I've interpreted the chain of comments as "Nuclear workers which were laid off _now_ can easily be absorbed by data centers almost immediately".
Could you elaborate why is that? They seem to be unrelated areas.
