  • Lead all NRC licensing activities, including design certification, combined license applications (COLs), and license amendments for BaRupOn's SMR and MMR programs.
  • Develop, review, and submit Safety Analysis Reports (SAR/FSAR), environmental reports, and all other required regulatory documentation to the NRC.
  • Manage pre-application engagement and formal licensing interactions with NRC staff, including review meetings, requests for additional information (RAIs), and public hearings.
  • Ensure timely and accurate responses to NRC inquiries, inspection findings, and enforcement actions.

Regulatory Compliance & Oversight

  • Ensure full compliance with all applicable U.S. nuclear regulatory frameworks, including 10 CFR Part 50, Part 52, and the emerging Part 53 framework for advanced reactors.
  • Monitor regulatory developments, proposed rulemaking, and NRC policy changes; assess impacts on BaRupOn programs and provide timely guidance to executive leadership.
  • Maintain and update the company's regulatory compliance matrix, tracking all license conditions, technical specifications, and reporting obligations.
  • Support internal audits, self-assessments, and corrective action programs to ensure sustained regulatory readiness.

Cross-Functional Collaboration

  • Partner closely with the CTO, CNO, and engineering teams to ensure regulatory requirements are embedded into reactor designs, safety analyses, and operational procedures from the outset.
  • Collaborate with project management and operations teams to align licensing milestones with overall program schedules and deployment timelines.
