Core Responsibilities

Primary Functions

Develop, review, and maintain the facility's Safety Analysis Report (SAR) and Technical Specifications to ensure they accurately reflect the plant's design and operational state.
Perform complex deterministic and probabilistic safety analyses (PSA/PRA) to assess plant response to postulated accidents and transient events.
Lead and participate in hazard identification and risk assessment activities, including Failure Modes and Effects Analysis (FMEA) and Hazard and Operability Studies (HAZOP).
Ensure strict compliance with federal regulations (e.g., 10 CFR 50, 10 CFR 70), industry codes, and standards (ASME, IEEE) by interpreting requirements and implementing compliant programs.
Provide authoritative nuclear safety oversight and review of engineering design changes, plant modifications, and temporary alterations to prevent adverse impacts on safety margins.
Serve as a technical subject matter expert during internal audits, external inspections, and formal interactions with regulatory agencies like the Nuclear Regulatory Commission (NRC) or the Department of Energy (DOE).
Conduct and document thorough investigations of operational events, incidents, and near-misses, performing root cause analysis to identify systemic weaknesses and develop effective corrective actions.
Develop, maintain, and implement emergency preparedness and response strategies, including conducting drills and exercises to ensure site readiness.
Analyze plant operational data, performance indicators, and industry operating experience to identify potential safety trends, vulnerabilities, and opportunities for improvement.
Prepare, review, and submit complex licensing documentation, technical reports, and formal responses to regulatory inquiries in a clear and defensible manner.
Champion and promote a robust nuclear safety culture throughout the organization by providing coaching, mentoring, and formal training to plant personnel on safety principles and expectations.
Evaluate the nuclear safety implications of new or revised procedures, maintenance plans, and work authorizations before their implementation.
Perform shielding calculations, dose assessments, and criticality safety analyses to ensure radiological safety for workers and the public during normal operations and accident conditions.
Support the management of nuclear fuel, including safety analyses for fuel loading, shuffling, storage, and handling activities.
Interface with multidisciplinary teams, including Operations, Maintenance, Engineering, and Radiation Protection, to integrate safety considerations into all plant activities.
Maintain the currency of the plant's design and licensing basis documentation, ensuring all changes are properly evaluated and incorporated.
Utilize and interpret results from complex engineering analysis codes (e.g., RELAP, MCNP, GOTHIC) to model plant behavior and validate safety margins.
Participate in the resolution of items within the Corrective Action Program (CAP), ensuring that issues related to nuclear safety are addressed rigorously and in a timely manner.
Conduct periodic safety reviews and self-assessments to proactively identify gaps in performance against established safety standards and regulatory requirements.
Provide on-call support for emergent plant issues, offering expert safety assessment and guidance to decision-makers under time-sensitive conditions.
Review and approve procurement specifications for safety-related equipment and components to ensure they meet design and quality requirements.
Develop and manage programs related to specific safety areas, such as fire protection, seismic qualification, or environmental qualification of equipment.

Secondary Functions

Support internal and external audits by preparing documentation and serving as a subject matter expert.
Mentor junior engineers and technical staff on nuclear safety principles and analytical techniques.
Participate in industry groups and conferences to stay abreast of emerging issues, best practices, and regulatory changes.
Contribute to the continuous improvement of safety analysis methodologies and department procedures.
