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
