I'm on the engineering side of the house so I'm not going to be helpful relating this specifically to RT or labs like SRS ORNL. For the nuclear power industry though, I don't think anybody "knows" what it's going to do yet. But, in general,
If they keep building new nukes they'll be hiring in multiple fields when you get finished (engineering, RT, HP, etc).
If Fukushima kills new nukes and requires a bunch of upgrades to the existing ones they'll be hiring when you get finished.
Most likely the next 10-20 years is going to be a combination of new nukes and mandated upgrades to deal with a much longer station blackout. This means a lot of companies competing for qualified people across the country at all experience levels. You might have to move around a bit until you have that experienced glow to you

but the jobs are there.
If they shut them all down tomorrow . . . they'll be hiring when you get finished. Decomissioning will carry you from new hire till retirement. Seriously doubt this will happen as it would require a major shift back to coal/natural gas or some new power source.
Hope you can see the pattern. Good luck.
