What this role is

Performs complex monitoring, testing, and troubleshooting of reactor and heat-conversion systems with minimal supervision. At the Lead Support Specialist (S4) level, the role owns team process and quality, cross-case patterns and process gaps, and drives team-level quality and efficiency. Mentors and coordinates the support team.

What this level does

  • Directs reactor operators during abnormal and emergency situations in accordance with emergency operating procedures, adapting the sequence of actions to the specific plant conditions encountered.
  • Develops and implements lockouts, tagouts, and clearances to allow equipment to be safely isolated and repaired, resolving conflicts between maintenance needs and safe plant configuration.
  • Authorizes maintenance activities on units and changes in equipment or system operational status, judging the plant-wide implications of each configuration change.
  • Supervises technicians' work activities to ensure equipment is operated within radiation-protection and environmental-safety policies, intervening when field conditions depart from procedure.
  • Acts as a working lead and informal guide for less experienced operators, applying extensive procedural knowledge to unfamiliar situations that lack a ready-made procedure.
Knowledge applied
Extensive knowledge of procedures and their administration, enough to adapt methods in unfamiliar plant conditions and administer clearances and configuration changes.
Complexity & problem solving
Understands the plant-wide implications of equipment status changes and emergency actions; recommends new solutions for situations without a ready procedure.
Collaboration & interaction
Directs reactor operators in emergencies, supervises technician work, and informally guides less experienced operators as a working lead.
Typical experience
4–6 years; advanced operating experience, typically holding or approaching senior operator license.

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.
