Some of those placement numbers may include temporary contract positions, which is a good way to get your foot in the door. These positions can be called different things by the many nuclear power plants out there.
FME Worker, Laborer, Junior Deconner, Deconner, Maintenance Helper, Fire Watch, Junior RP, Junior HP. There are others.
I don't think anybody is trying to feed you bad info, but you should have said straight up you would do anything. It sounded like in your original post you were targeting something specific but didn't know the name of it.
Try searching nukeworker: entry level, foot in the door, junior, deconner, begin with all forms of the word (ing, er), see above. Companies that do this are Bartlett, Atlantic, Shaw.
It is really hard to get a full time entry level job at a nuclear power plant right now unless qualified or you know someone. Much easier to get a contract position, but you have to work at it.
This info is on nukeworker. Some people on here do like an open forum but it would be a much more helpful if you took a look at what others have posted first. That would make it easier to help you, and you will get more out of it too. Maybe you did do some research, but your questions don't indicate that.
