There are a lot of great DOE sites with unique radiological challenges. Who knows, you may just learn something new. I've worked at Particle Accelerators (Brookhaven) and learned about subatomic particles like Quarks and Gluons as well as a lot of short lived activation products in air. (more than a power plant). I've worked at Fusion Reactors which allowed me first hand experience with hundreds of millions of curies of Tritium in water. I've worked at waste disposal sites which reinforced my DOT shipping knowledge. At Los Alamos I got to play with Plutonium and untold millions of alpha. Depleted Uranium in Minnesota, Tc-99 in Oak Ridge. Not to mention my visit to the craters in Nevada Test site. I honestly believe that my best learning experiences were at non commercial nuclear reactors. However, I also love the experience of a high reliability industry like commercial nuclear power. They all have their great attributes and learning opportunities.
Think of it as a great learning opportunity that you might not have otherwise had. Also, most of the DOE jobs are for over a year, so you can enjoy a stable job working 40 hours a week, every week.
