Core Responsibilities

Primary Functions

Lead on-shift control room operations and take ultimate responsibility for the safe, compliant operation of the reactor and associated balance-of-plant systems during your shift, ensuring adherence to operating procedures, tech specs, and company policies.
Supervise and mentor licensed operators and control room staff, setting performance expectations, conducting shift briefings and turnovers, and delivering timely feedback to develop operational competency and high-performing teams.
Make rapid, sound decisions during abnormal events and emergency conditions using established procedures and sound judgment, and coordinate immediate response actions with plant management, engineers, and emergency teams while maintaining a clear record of actions taken.
Ensure procedural compliance by verifying correct procedure selection and execution, challenging deviations, authorizing or initiating administrative changes when necessary, and documenting variances in shift logs and event reports.
Conduct and document thorough shift turnovers and handoffs, including detailed status of plant systems, outstanding work, ongoing mitigations, and follow-up actions to ensure continuity of safe operations between shifts.
Coordinate with plant maintenance, engineering, chemistry, and radiation protection organizations to manage plant conditions, schedule and prioritize work, and ensure effective communication of equipment status and limitations.
Maintain operational readiness for regulatory inspections and audits by ensuring documentation, logs, and records are complete, accurate, and available; support inspector interviews; and implement corrective actions from findings.
Serve as the primary on-shift interface with off-shift management, regulatory agencies, and external stakeholders during reportable events, maintaining clear, factual, and timely communications.
Validate and approve shift staffing, assignments, and reliefs to ensure adequate coverage, operator qualification, and compliance with collective bargaining agreements and station staffing matrices.
Oversee control room alarms and annunciation management strategies to ensure alarm clarity, prioritization, and operator situational awareness in coordination with engineering and human performance teams.
Lead initial event classification, notification, and reporting per station procedures and regulatory requirements, ensuring accurate and timely submittal of required notifications to regulators and corporate.
Ensure radiological and industrial safety practices are integrated into control room decisions, confirming work controls, access restrictions, and ALARA considerations are enforced during operations and maintenance activities.
Direct and participate in pre-job briefings and operational risk assessments for non-routine evolutions, ensuring mitigations are in place and staff understand roles, actions, and safety limits before work begins.
Maintain personal and team currency and qualification standards by ensuring operators complete required training, simulator sessions, requalification exams, and on-the-job training activities.
Approve and control plant mode changes and major operational evolutions within operator authority, ensuring technical justification, procedural compliance, and successful coordination of involved organizations.
Identify, document, and trend operational issues and near-misses; initiate or support root cause evaluations and drive corrective actions to improve reliability and safety culture.
Manage human performance expectations in the control room: enforce peer-checks, challenge-and-answer culture, procedural use, and error-likely situation mitigations to reduce the risk of human error.
Ensure computerized control room systems (DCS, MCR workstations, alarm systems) are functioning and coordinate with IT/engineers when degraded to maintain operational capability and logging integrity.
Represent the shift in plant operational meetings, giving concise status reports, trend observations, and recommendations for actions affecting plant safety and production.
Lead response to cybersecurity or equipment degradation events by coordinating with technical experts, implementing protective actions, and ensuring operational decisions preserve safety and compliance.
Authorize or recommend entry into plant conditions that require higher-level approval (e.g., technical specification actions, major deviations) and ensure formal documentation and approvals are obtained as required.
Serve as the on-shift focal point for outage support as needed—directing temporary configurations, managing tech spec implications, and ensuring safe interface of maintenance activities with ongoing operations.
Maintain and update shift logs, event reports, and operator narratives with clear, comprehensive, and timely information to support investigations, regulatory reporting, and operational continuity.

Secondary Functions

Participate in and often lead emergency preparedness drills, table-top exercises, and regulatory readiness training to validate response capabilities and identify improvement opportunities.
Collaborate with engineering and maintenance to support system design reviews, plant modifications, and human factors assessments that affect control room operations and operator workload.
Support continuous improvement projects focused on procedure quality, alarm management, shift turnover process enhancements, and control room ergonomics to boost safety and efficiency.
Provide input into staffing plans, operator hiring decisions, and qualification matrices to ensure the control room team meets current and future operational requirements.
Contribute to outage planning and readiness reviews by identifying operational constraints, resource needs, and risk mitigations for planned evolutions.
Support departmental reviews and performance metrics tracking (e.g., UPSR, human performance indicators, event frequency) and lead actions to address adverse trends.
Assist in preparation and review of licensing amendments, procedure revisions, and technical specification interpretations by providing on-shift operational insights.
Act as a subject-matter resource for contractor work affecting plant operation, ensuring contractor activities are integrated safely and under appropriate controls.
Lead shift-level safety meetings and toolbox talks to reinforce expectations, communicate lessons learned, and heighten awareness of current station issues.
Cover for adjacent supervisory roles as necessary during rotations, ensuring continuity of leadership and decision-making across broader operations.
