Day in the life
A Day in the Life of a Nuclear Reactor Operator
What nuclear reactor operators actually do from the start of a shift to the end: the tasks, tools, schedule and realities of the job.
Take a detailed turnover in the control room. From there, the day usually includes control reactor power and systems, monitor instruments and alarms, and perform surveillance tests. Plants run around the clock, so operators work rotating 12-hour shifts, plus training weeks.
