From an old HP perspective, they're both contaminated - so it didn't matter (some more so than others but that goes with the job). From a dose perspective - same as above, although I will admit the daily walk down with ops at Hatch was not fun (my only operating BWR experience and I picked up some dose doing those -
). Things have changed a lot with all the mergers but I would have to agree that the area the plant is located in will make a big difference as will the management. Interview with both, and while you're there check out the area and the people (unless it's a phone interview). And even if it's by phone, there's a lot of good information here. BTW, good luck.
