My very first HP position was for a Jr. HP at Big Rock Point for doing surveys for their decommissioning. I informed the contracting company that I didn't have any HP experience, but did have some other nuclear experience, and they told me that none was required, only a 'warm body'... so I told them if they were willing to teach me, I was more than willing to be a warm body for them. That job lasted a year for me. So, if your wife wants to get into something now, I would suggest going the D&D route. I think it would be very difficult for her to get into doing HP work, on the road, for the outages, with no experience at all. However, there is deconning available at some sites. I would suggest calling Bartlett and ask them what they can do for her.
GOOD LUCK!!
