Probabilistic Risk Engineer II

Primary Responsibilities

• Develop and maintain PRA logic models and supporting thermal-hydraulic analyses used for risk quantification and licensing support
• Build Level 1 and Level 2 PRA models for internal and external events across full power and shutdown operating conditions
• Support thermal-hydraulic modeling (RELAP5-3D, MELCOR) to simulate core and containment response in severe accident scenarios
• Affiliate with event trees and fault trees to evaluate key risk metrics such as core damage frequency (CDF) and large release frequency (LRF)
• Support ongoing updates and maintenance of 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)
• Interface with design teams to communicate PSA insights and support design decision-making
• Ensure consistency, accuracy, and quality across PSA analyses and deliverables
• Contribute to technical documentation supporting regulatory and licensing activities

Requirements

• Bachelor’s degree in Nuclear Engineering, Mechanical Engineering, or a related field
• 4–6 years of experience in probabilistic risk assessment and/or thermal-hydraulic safety analysis within the nuclear industry
• Familiarity with thermal-hydraulic behavior of light water reactors (LWRs)
• Proficiency with PSA and modeling tools (e.g., CAFTA, SAPHIRE, RiskSpectrum, RELAP5-3D, MELCOR)
• Working knowledge of ASME/ANS PRA Standards and NRC or IAEA risk guidance
• Ability to interpret analysis results and communicate technical insights clearly
• Strong technical writing, communication, and interpersonal skills
• Ability to collaborate effectively within a multidisciplinary engineering team
• Eligible to work under 10 CFR Part 810
