Job Description

The Probabilistic Safety Analysis (PSA) Engineer III supports Holtec’s advanced reactor development by leading probabilistic safety analysis (PSA) efforts for the SMR‑300 program. This role is part of a multidisciplinary engineering team responsible for risk‑informed design, safety analysis, and licensing of next‑generation nuclear technology. The position requires deep technical expertise in PSA and thermal‑hydraulic modeling, along with the ability to translate complex risk insights into actionable design improvements within a fast‑paced, highly regulated environment.

Location: Camden, NJ Waterfront Campus with other locations available!

  • This position may be based at one of several Holtec locations across the United States. Relocation assistance available!

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
