Probabilistic Risk Engineer III

Primary Responsibilities

• Lead development of PSA models and supporting thermal-hydraulic analyses for risk-informed design and licensing
• Develop Level 1 and Level 2 PRA models for internal and external events across full power and shutdown conditions
• Perform thermal-hydraulic modeling (RELAP5-3D, MELCOR) to simulate core and containment response in severe accident scenarios
• Develop and quantify event trees and fault trees to evaluate key risk metrics such as core damage frequency (CDF) and large release frequency (LRF)
• Maintain and update PSA models as SMR-300 design evolves
• Apply PSA results to support risk-informed programs (e.g., RTNSS, D-RAP, 10 CFR 50.69 categorization)
• Partner with design engineers to integrate PSA insights into system and plant design decisions
• Mentor junior engineers on PSA methodologies, tools, and best practices
• Ensure technical accuracy, quality, and consistency across all PSA deliverables
• Support regulatory interactions and documentation related to safety analysis and licensing

Requirements

• Bachelor’s degree in Nuclear Engineering, Mechanical Engineering, or a related field
• 6–10 years of experience in PSA and/or thermal-hydraulic safety analysis within the nuclear industry
• Strong understanding of light water reactor (LWR) thermal-hydraulic behavior
• Expertise with PSA and modeling tools (e.g., CAFTA, SAPHIRE, RiskSpectrum, RELAP5-3D, MELCOR)
• Experience with PSA specialty areas such as external hazards (fire, flood, seismic) or low power/shutdown analysis preferred
• Knowledge of PSA regulatory frameworks and ASME/ANS PRA standards
• Strong analytical, technical writing, and communication skills
• Ability to work cross-functionally in a complex engineering environment
• Eligible to work under 10 CFR Part 810
