Dark Wing pointed out that nuclear power plant operators who acquired their skills tend to be ex-career military, i.e., retired after 20 years of service. That puts them in the 40+ year-old age cohort, and excludes the low-risk 20-39 year-old age cohorts.
So nuclear power plant control room staff are almost all in the higher-risk age cohorts. That completely skews your statistics.
The age statistics have been posted here over and over again.
The death rates drop dramatically in a step-wise fashion.
40 to 60 puts you in the mid-range...
Please, do some research here.
