Not in my experience. Usually by the time one reaches the Control Room and assuming they were married when they were an NLO they've spent around 10 to 15 years in the industry already and their wives know what it's like to live with a nuke.
I was on 4 different shifts as a Licensed Operator at my old plant
1: All Control Room Operators were married, one had been divorced right after he got out of the Navy and was happily remarried.
2: Same deal, the operator who had been divorced was the same guy as in case 1.
3: Seven ROs and SROs, all happily married. One had been divorced but this was long before he was in Operations.
4: All happily married. One had been divorced when he was a Non Licensed Operator 16 years before.
