  • Author and review critical engineering documentation, including design basis documents, technical reports, safety analyses, and operational procedures to support plant modifications and operations.
  • Act as a primary technical interface with regulatory bodies (e.g., CNSC), preparing and presenting engineering assessments and safety case arguments to support licensing activities.
  • Apply advanced fracture mechanics principles to evaluate flaw tolerance and predict the crack initiation and growth behavior in zirconium alloy components.
  • Lead or support the technical disposition of non-conformances, operational events, and emergent component issues, providing timely and robust engineering solutions.
  • Develop sophisticated predictive models to forecast component degradation mechanisms such as creep, growth, and hydriding, informing strategic maintenance and replacement decisions.
  • Provide expert technical oversight and review of work performed by external vendors, consultants, and contractors to ensure compliance with stringent nuclear standards and project requirements.
  • Initiate and manage research and development (R&D) programs aimed at improving fuel channel performance, extending component life, and developing next-generation designs.
  • Prepare and deliver technical presentations to senior management, industry peers, and technical committees on fuel channel performance, projects, and strategic initiatives.
  • Support plant outage planning and execution by providing engineering expertise, work package reviews, and on-site support for fuel channel related activities.
  • Conduct detailed failure analysis and root cause investigations for fuel channel component issues to prevent recurrence and enhance system reliability.
  • Interface directly with plant operations, maintenance, and chemistry departments to provide integrated solutions and ensure a holistic approach to component health.
  • Evaluate the impact of changing plant operating conditions or system modifications on the structural and functional performance of the fuel channel assembly.
  • Mentor and provide technical guidance to junior engineers and technical staff, fostering a culture of technical excellence and continuous learning within the team.
  • Ensure all engineering work is performed in strict accordance with the nuclear quality assurance program, company procedures, and relevant codes and standards (e.g., ASME, CSA).
  • Develop and validate complex analytical models against experimental data or in-service measurements to increase the accuracy of performance predictions.
