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
Assist in development and quantification of 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
