Job summary

Holtec International in Camden, NJ seeks a Probabilistic Safety Analysis (PSA) Engineer I to advance PSA methodologies for the SMR-300 program and collaborate with design, safety, licensing, and systems engineering teams to ensure robust risk-informed design and safe, reliable plant performance.

You will contribute to PRA model development, thermal-hydraulic analyses, event/fault tree logic, and regulatory compliance while growing with a multidisciplinary team dedicated to next-generation

Qualifications

• B.S degree in nuclear engineering, mechanical engineering, or closely related field from an accredited college or university.
• Familiarity with thermal-hydraulic behavior of light water reactors (LWRs).
• Familiarity with probabilistic risk assessment and/or thermal-hydraulic analysis methods for light-water reactors.
• Exposure to industry codes such as CAFTA, SAPHIRE, RiskSpectrum, RELAP5-3D, or MELCOR.
• 2-4 years of experience in probabilistic risk assessment and/or thermal-hydraulic safety analysis for nuclear facilities.
• Excellent technical writing, interpersonal, and communication skills.
• Eligible to work under 10 CFR Part 810

Responsibilities

• Support development of PRA modules and/or associated thermal-hydraulic analyses under the supervision of senior engineers.
• Develop Level 1 and Level 2 PRA models for internal and external events during full power and low power / shutdown operating modes.
• Thermal-hydraulic analysis specialization: support RELAP5-3D and MELCOR modeling to simulate core and containment response for severe accident scenarios that inform PRA quantifications.
• Logic modeling specialization: support development of event trees and fault trees to estimate key design risk metrics including core damage frequency (CDF) and large release frequency (LRF).
• Support PSA model maintenance and updates that occur periodically as the SMR-300 design matures
• Use PSA results to support implementation of risk-informed programs; for example, Regulatory Treatment of Non-Safety Systems (RTNSS), Design Reliability Assurance Program (D-RAP), 10 CFR 50.69 risk-informed categorization and treatment of SSCs.
• Interface with the design team to communicate and implement PSA insights
• Ensure consistency and quality of all PSA deliverables
