I work as a mechanic at a nuclear plant. Lucked out with ending up here, didn't really have any career path planned. We do basic routine maintenance, replace/clean/repair valves, pumps, compressors, etc. We also handle all the fuel movements (new fuel, refueling/defueling, dry fuel and the like). Been pretty awesome so far, got to see Cherenkov radiation first hand, (that glowy effect you see in movies/T.V. It's real, only it's blue, not green) and get to be the last person for thousands of years to be able to touch the brand new fuel. The worst is when the crap breaks while at power and they don't wanna shut down. Going in at power SUCKS!! It's hot, you have to follow an EXACT path to the work, and they constantly ask for updates on the work/tell you to go faster.
Normal work is basically 10 hours a day, 4 days a week. The work itself is usually fairly simple (though the paperwork can cumbersome. At times it seems like 4 different people have to sign off just to flip a lightswitch). Of course, the flip side is...while we wait for all that paperwork, we sit around and shoot the breeze, browse interwebs, etc. Normal pay is $31/hr, then there's overtime, but thanks to NRC rules/union workings, we can also get what is called "sweet deal." That basically is double time and a half. Doesn't happen often, but when it does...
Again, I am really grateful job situation turned out how it did, especially considering how the economy is for college grads still. If I had gone to college, think I'd mostly like would have dropped out, didn't have any real discipline then. I've been thinking about going now though, turning 30 this year, so it's not TOO late, but "grumpy old guy in class" age is fast approaching.
