Senior Engineer - Nuclear Deterministic Safety Analysis (LOCA & Containment)

GE Vernova develops nuclear energy technologies, including the BWRX-300 reactor. The Senior Deterministic Safety Analysis Engineer will lead thermal-hydraulic and plant transient analyses focused on LOCA, containment performance, and passive safety systems, while preparing regulatory documentation, verifying technical deliverables, and communicating solutions to customers and regulators.

Responsibilities:

• Lead a variety of projects including technical evaluations and analyses in the area of Anticipated Operational Occurrences, Anticipated Transients without Scram, Reactor Heat Balance, and Thermal Hydraulic Fuel Channel Analyses
• Serve as a subject‑matter expert for BWRX‑300 LOCA and Containment behavior, leading development, maintenance, and application of DSA methods and results that implement key topical reports (e.g., LOCA summary, containment performance, and containment evaluation method)
• Perform plant thermal‑hydraulic evaluations and analyses in the areas of LOCA (large and small breaks inside and outside containment), high‑energy line break (HELB), Containment pressure/temperature and sub‑compartment response, passive containment cooling system (PCCS) and Isolation Condenser System (ICS) performance, Fire Safe Shutdown, Annulus Pressurization Loads, and RIPD analyses
• Develop, document, and apply TRACG‑based evaluation models for LOCA mass‑and‑energy release and fuel acceptance criteria, and GOTHIC‑based models for containment response, including conservative (CN‑DSA) and best‑estimate (EX‑DSA) applications consistent with RG 1.203 / CSAU practices
• Deliver products at a consistently high and sustainable level in accordance with customer requirements, business procedures, and regulatory agency guidelines
• Utilize unique opportunities to create and/or improve cutting‑edge automation and methods
• Prepare thorough and accurate technical reports, correspondence, documentation, and calculations, including regulatory submittals, responses to Requests for Additional Information (RAIs), and technical justifications related to LOCA and containment
• Perform technical verification of engineering technical deliverables
• Prepare, communicate, and present complex technical issues to internal and external customers and recommend solutions, including explaining integrated plant response for LOCA/containment events to regulators, utilities, and partners
• Perform in cross‑disciplinary settings, engaged with interfacing teams responsible for mechanical design, core design, licensing, systems design, civil/structural design, or other affiliated organizations to find optimum customer solutions, ensuring LOCA and containment requirements are reflected in evolving plant design
• Ensure work is performed with high quality in accordance with regulatory rules and regulations, customer requirements, and business quality assurance standards

Requirements:

• B.S. Degree in Engineering Discipline (Nuclear, Mechanical, Physics or similar)
• 8+ years of relevant nuclear experience with at least 5+ years of demonstrated experience in thermal‑hydraulic safety analysis (direct experience with LOCA and/or containment analysis is strongly preferred)
• M.S. Degree in Engineering Discipline (Nuclear, Mechanical, Physics or similar)
• 6+ years of relevant nuclear experience with at least 3+ years of demonstrated experience in thermal‑hydraulic safety analysis (direct experience with LOCA and/or containment analysis is strongly preferred)
• PHD in Engineering Discipline (Nuclear, Mechanical, Physics or similar)
• 4+ years of relevant nuclear experience with at least 1+ years of demonstrated experience in thermal‑hydraulic safety analysis (direct experience with LOCA and/or containment analysis is strongly preferred)
• This role requires access to U.S. export-controlled information. If applicable, final offers will be contingent on ability to obtain authorization for access to U.S. export-controlled information from the U.S. Government
• The preferred work location for this role is at the GEH Headquarters Wilmington, NC or the GEV hub in Atlanta, GA but qualified remote candidates will be considered
• Master's Degree or Ph.D. Degree in Engineering; or Senior Reactor Operator Certification
• Experience with BWR core simulation and thermal‑hydraulic systems codes
• Experience with BWR LOCA, Containment, ICS/PCCS performance, HELB, Fire Safe Shutdown, Annulus Pressurization Loads, and RIPD analyses
• Extensive knowledge of BWR Systems and integrated plant response
• Extensive knowledge of the fundamental principles of nuclear engineering such as nuclear physics, thermal hydraulics, and mechanical design, as applied to BWR
• Expertise in two‑phase thermal‑hydraulic analysis techniques
• Experience with standard engineering work planning and design process techniques
• Knowledge of reactor licensing requirements and deterministic safety analysis methodologies (e.g., CN‑DSA, EX‑DSA, RG 1.203/CSAU, REGDOC‑2.4.1 / REGDOC‑2.5.2)
• Experience with BWR/PWR T‑H systems codes such as TRACG (strongly preferred), RELAP, and TRACE
• Experience in Best Estimate methodology development (e.g., TRACG)
• Experience with Containment codes such as GOTHIC, including multi‑volume nodalization and passive heat removal modeling
• Experience with Best Estimate and CSAU applications
• Programming experience such as C#, FORTRAN, or PYTHON
• Acts with honesty and integrity, takes ownership of their work, and communicates with confidence and clarity
• Highly motivated and committed to delivering quality results, always looking for ways to improve, and eager to mentor others and sustain organizational expertise in LOCA and containment analysis
