What nuclear reactor operators do

Nuclear reactor operators run some of the most tightly controlled machines in the world. From the control room they adjust reactor power, monitor reactor coolant, steam and electrical systems, perform surveillance tests, respond to alarms and follow strict procedures. Non-licensed operators make rounds in the plant; licensed reactor operators and senior reactor operators run the controls.

Most operators have a high school diploma and complete years of plant training before earning an NRC license. Many come from the Navy nuclear program. The field is small and employment is projected to decline, but pay is among the highest for jobs without a degree.

Typical duties

  • Control reactor power and systems
  • Monitor instruments and alarms
  • Perform surveillance tests
  • Respond to abnormal and emergency conditions
  • Follow technical specifications
  • Coordinate maintenance clearances
  • Train continuously and pass requalification

Work environment and schedule

Operators work in secure nuclear plant control rooms and plant areas with radiation controls and strict security.

Schedule: Plants run around the clock, so operators work rotating 12-hour shifts, plus training weeks.

A day in the life

  1. Take a detailed turnover in the control room.
  2. Review technical specification status.
  3. Perform a scheduled surveillance test on a safety pump.
  4. Adjust turbine load per dispatch.
