Core Responsibilities

Primary Functions

Operate, monitor and control nuclear reactor systems and associated balance-of-plant equipment in accordance with licensed procedures, technical specifications, and plant operating limits to ensure safe, continuous operation of the facility.
Perform reactor startup, power ascension, power reductions, and shutdown evolutions following written procedures and checklists; verify pre-start conditions and complete required operator rounds and log entries.
Serve as a control room watchstander: maintain surveillance of reactor parameters, alarms, and safety systems; initiate corrective actions and notify supervisory staff during abnormal or emergency conditions.
Implement and follow strict procedural compliance and human performance tools (peer checks, pre-job briefs, independent verifications) to eliminate errors and maintain nuclear safety culture.
Conduct pre- and post-evolution briefings, complete required shift turnover reports, and maintain accurate, auditable operating logs, shift books and regulatory records.
Conduct routine and directed equipment alignments, valve operations, and system lineups for core instrumentation, reactor coolant, cooling systems, and auxiliary systems to support plant operational requirements.
Perform surveillance tests, functional checks, and preventive maintenance tasks per Technical Specifications and Surveillance Test Procedures (STPs) and ensure accurate completion of work orders.
Monitor radiological conditions, operate radiation monitoring instrumentation, and enforce ALARA principles while coordinating with Radiological Control to limit worker and public dose.
Perform chemistry sampling, analysis coordination, and control actions to maintain required reactor coolant and secondary system chemistry specifications and to manage corrosion or contamination risks.
Troubleshoot instrumentation, control system anomalies, and process deviations to identify root causes and coordinate corrective maintenance with I&C and mechanical technicians.
Execute and support plant outage activities: work package execution, equipment isolation, system restoration, delineation of tests, and coordination across operations, maintenance and engineering teams to meet schedule and safety requirements.
Maintain and ensure proper implementation of lockout/tagout, confined space entry, and other hazard controls during maintenance, testing, and upgrades in accordance with company policies and regulatory standards.
Support and participate in emergency preparedness exercises, station blackout (SBO) drills, and casualty control evolutions; act as a primary operator in emergency response organization when required.
Review, approve (within delegated authority) and implement temporary modifications, technical work documents, and procedural changes with oversight from licensing/engineering to maintain configuration control.
Provide on-the-job training, mentoring and qualification support for reactor operator candidates and junior operations staff; evaluate performance against qualification standards and conduct performance feedback.
Participate in corrective action program (CAP) by documenting equipment issues, procedural deficiencies and human performance events; lead or support root cause analyses (RCA) and implement corrective actions.
Ensure compliance with applicable NRC/DOE/INPO/EPRI regulatory requirements, license conditions, and internal policies; prepare for and support regulatory inspections and audits.
Maintain physical security, access controls, and material condition of reactor plant areas; coordinate with security and facility services to resolve equipment or environmental issues affecting operations.
Coordinate with engineering to support plant modifications, design change testing, and system startups to verify operability and resolve issues identified during post‑maintenance testing.
Implement quality assurance and configuration management practices for operations documentation, operating limits, and procedures to preserve the safe technical baseline of the facility.
Produce and deliver clear, technically accurate shift briefings, operating reports, and handovers to ensure continuity and institutional knowledge retention across shifts and teams.
Analyze operational data and performance indicators (availability, forced outage rate, plant trips) to identify trends and contribute to continuous improvement initiatives that enhance reliability and safety.

Secondary Functions

Support plant engineering by executing system walkdowns, collecting field data, and validating as‑built conditions for modifications and safety analyses.
Assist with supplier/vendor surveillance during equipment installs, post-maintenance testing, and vendor witness testing to ensure vendor work meets plant and regulatory requirements.
Contribute to development and revision of operating procedures and emergency procedures by providing hands-on operational insights and lessons learned.
Participate in cross-functional process improvement teams (lean, kaizen) to remove barriers to safe, efficient operations and reduce human performance related events.
Evaluate and recommend tools, spare parts, and inventory improvements to reduce outage durations and improve mean time between failures (MTBF) of critical plant equipment.
Provide technical support for licensing activities including preparation of operating experience reports, technical justifications, and submittals required by regulators.
