What this role is

Performs reactor physics and thermal-hydraulic engineering analysis to support safe, efficient operation of a nuclear power plant. At the Mid-Level Professional (P3) level, the role owns features or a sub-system end-to-end, adapts existing approaches, and drives project / team outcomes. Mentors juniors informally.

What this level does

  • Independently conduct startup and shutdown procedures on the nuclear reactor, planning and sequencing the manipulations within licensed limits
  • Operate nuclear power reactors in accordance with policies and procedures to protect workers from radiation and ensure environmental safety
  • Participate in nuclear fuel element handling activities, including preparation, transfer, loading and unloading
  • Respond to system or unit abnormalities, diagnosing the cause and recommending or taking corrective action
  • Develop or implement lockouts, tagouts or clearances so equipment can be safely repaired
Knowledge applied
Applies deep procedural and systems knowledge to plan and execute diverse evolutions — startups, shutdowns, fuel handling — with day-to-day independence.
Complexity & problem solving
Evaluates identifiable factors to diagnose abnormalities and determine corrective action across coupled systems.
Collaboration & interaction
Networks with senior operators and maintenance; coordinates clearances and fuel-handling activities.
Typical experience
Licensed reactor operator with 5+ years, or a degreed operator with 3+ years of plant experience.

Skills at this level

Reactor Control Manipulation
Positions control rods and regulates flux level, reactor period, coolant temperature and rate of power flow to control reactor power within licensed limits.
Operations Monitoring
Watches gauges, dials and indicators to confirm reactor and generator systems are running normally and to detect the effects of generator loading on other equipment.
Startup and Shutdown Evolutions
Conducts the sequenced procedures that bring a nuclear reactor critical or take it subcritical, following standard operating procedures at each step.
Abnormal Condition Diagnosis
Responds to system or unit abnormalities by identifying the cause from plant indications and recommending or taking corrective action.
Emergency Procedure Execution
Implements the plant's emergency operating procedures when off-normal or accident conditions arise, carrying out the prescribed operator actions.
Nuclear Fuel Handling
Participates in fuel element handling activities including preparation, transfer, loading and unloading of nuclear fuel.
Lockout/Tagout and Clearances
Develops and implements lockouts, tagouts and clearances that isolate equipment so it can be safely repaired without hazard to personnel or the reactor.
Radiological and Environmental Safety
Operates the reactor in accordance with policies and procedures that protect workers from radiation and ensure environmental safety.
Operational Logkeeping
Records reactor and system data in operating logs at prescribed intervals to document plant status and support shift turnover and regulatory review.
Shift Communication and Dispatch
Dispatches orders and instructions to auxiliary and field personnel via radiotelephone or intercommunication systems to coordinate equipment operation during evolutions.
Control Room Command
Oversees the control panel and overall unit operation, directing and supervising reactor operators through routine and off-normal evolutions.
Regulatory Compliance (NRC)
Carries responsibility for meeting NRC licensing requirements and radiological safety obligations across the plant's operation.
Operator Instruction
Trains and qualifies reactor operators, building the crew mental representations needed to handle transients and casualties beyond routine procedures.
