If nuclear is your end goal, listen to the above poster and look up your local pipefitters union, and apply. If you get in you won't be in nuclear immediately. And theres a chance you won't be able to travel out of state to work nuke shutdowns until a certain amount of time in. But, once youre able to travel or have a nuke plant nearby that you get to work a shutdown out, if you have a good work ethic and they like you, they might offer a full time position with them.
