Core Responsibilities

Primary Functions

Directly manipulate reactor, turbine, and generator controls to manage reactor power level and electricity output, ensuring stable and efficient plant operation in strict accordance with technical specifications.
Continuously monitor all control room indications, including plant process computers, digital displays, and alarm panels, to assess the operational status of the reactor and all supporting safety systems.
Execute complex and infrequent plant evolutions, including reactor startups, plant shutdowns, and significant power level changes, following highly detailed and prescriptive procedures.
Immediately respond to all plant alarms and abnormal conditions by diagnosing the situation, referencing appropriate procedures, and taking decisive corrective actions to restore the plant to a safe and normal state.
Perform comprehensive and regularly scheduled surveillance testing on critical safety systems and components to verify their operability and ensure they will function as designed if needed.
Implement Emergency Operating Procedures (EOPs) and act as a key member of the Emergency Response Organization during drills, simulations, and actual plant emergencies to mitigate potential consequences.
Authorize and oversee all work activities within the plant by managing the work control process, including the application and removal of equipment clearances and protective tagging (Lockout/Tagout).
Maintain a meticulous and legally binding control room log, documenting all operational activities, equipment status changes, significant communications, and any deviations from normal operation.
Direct the field activities of Non-Licensed Operators, ensuring that all equipment manipulations and alignments outside the control room are performed correctly and safely.
Conduct thorough and effective shift turnover briefings, clearly communicating all pertinent plant status information, ongoing activities, and potential vulnerabilities to the oncoming operations crew.
Perform independent verifications of safety-significant component realignments and operator actions to provide a critical defense-in-depth barrier against human error.
Proactively identify equipment deficiencies, potential safety hazards, and procedural weaknesses, and formally document them in the station's Corrective Action Program for resolution.
Control and monitor all radioactive liquid and gaseous releases, ensuring full compliance with environmental regulations and maintaining doses As Low As Reasonably Achievable (ALARA).
Calculate, track, and manage core reactivity and thermal margins to ensure the reactor is always operated well within its established nuclear and thermal safety limits.
Coordinate operational activities with Maintenance, Engineering, Chemistry, and Radiation Protection departments to facilitate plant work while maintaining overall plant stability and safety.
Participate in an intensive and continuous requalification training program, which includes regular simulator evaluations, to maintain and enhance operational skills and knowledge.
Review and provide operational feedback on procedure changes, design modifications, and temporary alterations to ensure they are safe and operationally sound.
Maintain a questioning attitude and a conservative bias for safety at all times, pausing and seeking clarification when faced with unexpected or uncertain conditions.
Uphold and enforce all site standards related to industrial safety, radiological safety, and security to foster a secure and safe working environment.
Fulfill all requirements to maintain an active Reactor Operator license issued by the U.S. Nuclear Regulatory Commission (NRC) for the specific facility.

Secondary Functions

Actively participate in safety committees and performance improvement initiatives to enhance overall plant safety and operational excellence.
Mentor and provide on-the-job training for Operator Trainees and newly licensed operators to develop the next generation of control room staff.
Support outage and refueling activities by performing specialized tests, system alignments, and monitoring duties specific to the outage schedule.
Assist the training department by providing operational expertise for the development of new training materials and simulator scenarios.
