  • Interface directly with regulatory bodies, such as the Nuclear Regulatory Commission (NRC) or the Department of Energy (DOE), to present safety analyses and respond to Requests for Additional Information (RAIs).
  • Provide expert technical support to the plant's operations department, emergency response organization (ERO), and engineering teams during normal operation and emergent plant conditions.
  • Evaluate nuclear-criticality safety for fissile material operations, including storage, handling, and transportation, ensuring subcriticality is maintained under all credible conditions.
  • Prepare, verify, and validate computer software and calculation methodologies used for safety analysis in accordance with stringent quality assurance standards like ASME NQA-1.
  • Analyze potential radiation shielding requirements and perform dose assessment calculations for both workers and the public for normal operations and accident scenarios.
  • Review and approve vendor-supplied technical documents, calculations, and analyses to ensure they meet project specifications and safety requirements.
  • Champion a robust safety culture by actively participating in safety reviews, corrective action programs, and self-assessments to drive continuous improvement.
  • Develop technical bases and justifications for changes to plant Technical Specifications and other licensing basis documents.
  • Lead and participate in multidisciplinary teams to resolve complex technical issues and challenges related to nuclear safety and plant performance.
  • Mentor junior analysts and engineers, providing guidance on analytical techniques, regulatory requirements, and engineering best practices.
  • Support the development and implementation of safety analysis methodologies for new and advanced reactor designs, including Small Modular Reactors (SMRs).
  • Perform containment analysis to demonstrate the integrity and performance of the containment structure under severe accident pressure and temperature loads.
  • Evaluate the safety significance of operating events and equipment failures, determining reportability requirements and contributing to root cause analyses.
  • Prepare and present detailed technical reports, calculations, and presentations to internal management, oversight committees, and external stakeholders.
  • Support fuel reload design and core operating limits analysis by verifying that safety criteria are met for the planned fuel cycle.
  • Maintain up-to-date knowledge of evolving industry standards, regulatory changes, and analytical tool advancements to ensure the continued robustness of the safety analysis program.
