What this role is

Lead technical expert directing reactor physics analysis and thermal-hydraulic modeling for a nuclear power plant. At the Principal Support Specialist (S5) level, the role owns function-wide support practice, program-level and systemic support problems, and drives support strategy across the function. Subject-matter authority; shapes the practice.

What this level does

  • Oversees the control panel and overall operation of the reactor as senior reactor operator, directing and supervising reactor operators through routine operation, testing, and emergency response.
  • Supervises other operators in responding to abnormal conditions and implementing emergency procedures, resolving complex, simultaneous plant events that require integrating multiple system behaviors.
  • Contributes to the creation and revision of operating and emergency procedures, translating operating experience and abnormal events into improved step sequences and cautions.
  • Serves as the licensed authority for evolutions that carry the highest consequence — fuel handling campaigns, mode changes, and shutdown/startup — making the final operational calls the RO tier cannot.
  • Trains and mentors the operator crew as a working lead, developing operator technique and shift discipline while remaining the senior technical reference on plant systems.
Knowledge applied
Highly skilled senior reactor operator; contributes to the creation and revision of operating and emergency procedures within the operations discipline.
Complexity & problem solving
Resolves complex, concurrent plant events and develops improved operating techniques and procedure concepts from operating experience.
Collaboration & interaction
Acts as working lead of the shift operating crew, directing and supervising operators and providing peer guidance and training.
Typical experience
6+ years; expert licensed senior reactor operator (SRO), top licensed operator tier below shift management.

Skills at this level

Operations Monitoring
Watches instrumentation panel gauges, dials, and display screens to confirm reactor and support systems are operating within prescribed limits and detects out-of-band conditions.
Reactor Control Manipulation
Adjusts controls to position control rods and regulate flux level, reactor period, coolant temperature, and rate of power flow in accordance with standard operating procedures.
Radiation Leak Detection Response
Monitors radiation-detection sensors and acts to ensure any leak is detected and addressed quickly, escalating alarms to the licensed operator on shift.
Nuclear Fuel Element Handling
Prepares, transfers, and loads or unloads nuclear fuel elements, verifying each move against the fuel handling procedure before proceeding.
Abnormal Condition Diagnosis
Responds to system or unit abnormalities by diagnosing the cause and recommending or taking corrective action, judging when emergency operating procedures apply.
Operating Log Keeping
Records instrument readings, valve line-ups, equipment status, and evolution steps in operating logs at prescribed intervals and formats to document plant status.
Lockout / Tagout and Clearance Administration
Develops and implements lockouts, tagouts, and clearances that isolate equipment so it can be safely repaired while preserving safe plant configuration.
Emergency Operating Procedure Execution
Directs reactor operators during emergencies in accordance with emergency operating procedures, adapting the action sequence to actual plant conditions.
Plant Configuration Authorization
Authorizes maintenance activities and changes in equipment or system operational status, weighing the plant-wide safety and operational implications of each change.
Teamwork and Clear Communication
Provides clear instructions to the operating crew on operating procedures, repairs, and emergency response, and communicates plant status across control-room and field teams.
Radiation and Environmental Safety Supervision
Supervises technicians' work so equipment is operated within policies that protect workers from radiation and ensure environmental safety.
Operating Procedure Development
Contributes to creating and revising operating and emergency procedures by translating operating experience and abnormal events into improved steps and cautions.
