Years ago the site coordinator for the RP contract company would have a clerk or administrative assistant for the outage... not so much any more. However, you may have a shot with one of the bigger companies such as D&Z or whoever has the maintenance contract. Unfortunately, even with experience as a Legal Assistant (and I understand that is no small job) you probably could not translate that into more than admin assistant in the nuclear world (unless the utility is used to getting sued a lot.)
What does your husband do? What is his trade/craft? It is still fairly common for a Senior RP technician to get his wife/girlfriend an entry level deconner job but that is a big step down from being a legal assistant (no slam on deconners at all -- I have a deep respect for good deconners.) You could then work your way up, but it takes a while.
Good luck, what ever path you choose (or chooses you.)
