About the role

Aalo Atomics is seeking a skilled Licensing Engineer to lead and support licensing, regulatory strategy, and safety-basis development for advanced nuclear reactor projects, with emphasis on Non-Light Water Reactors (non-LWRs) and DOE/NRC-regulated facilities. The role applies risk-informed, performance-based (RIPB) methods (including NEI 18‑04/Licensing Modernization Project approaches), integrates PRA insights, and ensures compliance with NRC and DOE requirements throughout design, construction, and operation.

What you'll do

• Licensing Basis & Methodology
• • Lead or contribute to development of the project licensing basis using RIPB approaches and the Licensing Modernization Project (LMP) methodology (NEI 18‑04 and related guidance).
  • Establish and maintain the safety-focused design and licensing basis consistent with DOE/NRC expectations.
• Event Selection & Safety Analyses
• • Select and evaluate Licensing Basis Events (LBEs) (AOOs, DBEs, BDBEs ) and assess them against Frequency–Consequence (F–C) targets.
  • Perform or oversee deterministic safety analyses to demonstrate compliance with applicable regulatory limits (e.g., 10 CFR 50.34) and document results in PSAR/FSAR or other licensing submittals.
• SSC Safety Classification & Design Interface
• • Classify Structures, Systems, and Components (SSCs) into SR, NSRST, or NST categories, and define applicable codes, quality standards, and special treatments for design, fabrication, erection, testing, and procurement.
  • Work with design authorities and engineering teams to ensure design control, traceability to the design/licensing basis, and proper change management.
• Defense‑in‑Depth & Risk Assessment
• • Conduct risk‑informed/performance‑based evaluations of Defense‑in‑Depth (DID) adequacy and ensure multiple layers of protection are incorporated in design and programmatic features.
  • Integrate Probabilistic Risk Assessment (PRA) models and insights into LBE selection, design decisions, and safety cases.
• Regulatory Submissions & Stakeholder Interaction
• • Prepare, review, and manage licensing documents and technical reports (PSARs, FSARs, License Amendment Requests, COL/ML/ESP/CP/OL/SDAs as applicable).
  • Engage with NRC staff (pre-application and formal reviews), DOE oversight, vendors, national laboratories, and other stakeholders to present technical and regulatory arguments.
• Program & Procedure Support
• • Support development of operational programs, QA implementation (10 CFR 50, App. B where applicable), technical specifications, and training/qualification plans.
• Provide technical justification for exemptions or departures, when needed, backed by RIPB analyses.
• Communication & Teamwork
• • Prepare clear technical reports and presentations; lead or participate in Integrated Decision‑Making Process Panels (IDPP) or equivalent review boards.
  • Mentor junior staff and coordinate multidisciplinary teams to meet licensing milestones.

Required Qualifications & Skills

• Education: Bachelor’s degree in Nuclear Engineering, Mechanical, Electrical, Civil, Chemical, Fire Protection, or closely related engineering/science field.
• Experience:
• • Licensing Engineer: typically 2+ years of relevant nuclear industry experience with at least 1 year in nuclear operations/design or technical support.
  • Senior Licensing Engineer: 5+ years of progressive experience in nuclear licensing, design, operations, or safety analysis with demonstrated involvement in NRC/DOE regulatory processes.
• Technical Knowledge:
• • Strong understanding of nuclear reactor fundamentals (reactor theory, heat transfer, thermodynamics, fluid mechanics) and reactor systems.
  • Demonstrated proficiency with PRA methodologies and applications for licensing and safety analyses.
  • Familiarity with instrumentation & control (I&C) architectures and seismic qualification standards (e.g., ASCE/SEI 43‑19, ASME QME‑1, DOE/EH‑0545) and equipment qualification processes.
• Regulatory & DOE Knowledge:
• • Comprehensive understanding of U.S. nuclear regulations, particularly 10 CFR Parts 50 and 52; familiarity with Parts 73 and 100 preferred.
  • Specific knowledge of 10 CFR 50.69 and risk‑informed SSC categorization methods.
  • Awareness of applicable DOE requirements and standards (e.g., 10 CFR 830, 10 CFR 835, 10 CFR 851, DOE O 420.1, DOE O 426.2, DOE‑STD‑1271‑2025, DOE‑STD‑1027 series).
• Skills:
• • Excellent technical writing and oral communication for regulatory submittals and stakeholder interactions.
  • Strong analytical problem‑solving ability; experience applying RIPB tradeoffs to justify design and program decisions.
• Ability to work collaboratively in interdisciplinary teams and to lead or participate in technical review panels.
• Proficiency with common engineering analysis tools and PRA software (tool experience specified by employer).
