What this role is

Senior individual contributor who provides expert-level analysis of reactor physics and thermal-hydraulic performance to ensure safe, efficient plant operation. At the Expert Professional (P5) level, the role owns multiple systems or a technical domain, establishes the approach, and drives org / multi-team outcomes. Leads cross-team technical initiatives.

What this level does

  • Act as the senior authority on shift for reactor operations, exercising broad independent judgment on non-routine and off-normal evolutions affecting unit reliability
  • Serve as licensed operator instructor, developing crew mental models for handling transients and casualties beyond textbook scenarios
  • Lead the operations response to significant plant transients, integrating radiological safety, regulatory limits and equipment protection into a single coordinated plan
  • Carry end-to-end responsibility on shift for radiological safety and regulatory compliance across the plant
  • Resolve intangible operational trade-offs — power output versus equipment margin versus procedural conservatism — where established procedures give no single answer
Knowledge applied
Recognized shift expert who has moved beyond procedure execution into building robust crew mental representations for transients and casualties; instructs others.
Complexity & problem solving
Resolves intangible, high-stakes operational trade-offs where procedures do not prescribe a single answer, integrating safety, regulatory and equipment margins.
Collaboration & interaction
Builds influential relationships across operations, engineering and regulatory functions; serves as an operator instructor and shift authority.
Typical experience
12+ years, extensive licensed operating experience, often with instructor qualification.

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.
