Peach Bottom is a great place to work.
I was hired in 2008 as an NLO and am now just a few weeks away from becoming an RO.
I agree with the prior comments regarding how you should take the Chem Tech opportunity now and later, if you desire, and prove to have good work habits and procedural compliance, then transferring into OPS should be relatively easy.
As for the location comments: from my perspective, the amish are much more "noticeable" for those living in Lancaster/Millersville areas and those living up Rt.74 in the Red Lion area. By noticeable, I am referring to having to slow down behind a horse and buggy and wait for a clearing to pass. People living in those areas will generally see these delays on route to or from work by traveling Rt.74 and Rt.372.
I live in Rising Sun, MD which is about 25 minutes from Peach Bottom Atomic Power Station located in Delta, PA. Personally, I really do love living in this area. When I was younger and single, Lancaster, Millersville, and York were fun due to their nightlife. But now that I am a little older, married, and expecting our first child, I am very glad that we live in a more "country" atmosphere with 4.5 acres for the dogs and a lot less traffic congestion. I am minutes from Rt.1, Rt.272, Rt.273, & importantly I-95. During the summer, we are basically on our boat every other day on the North East River and Upper Chesapeake Bay area. Our marina, McDaniel Yacht Basin, is only a 15 minute drive away.
Enough ranting on my part. If you find this information helpful, feel free to send me a PM and I'd be happy to attempt to address any more of your questions or concerns regarding employment at Peach Bottom or living in the area.
