The
Probabilistic Safety Analysis (PSA) Engineer I will support the development and application of Probabilistic Safety Assessment (PSA) methodologies for Holtec International's SMR-300 advanced nuclear reactor program. Working within a multidisciplinary engineering team, this role will contribute to risk-informed design, safety analysis, licensing activities, and regulatory compliance by developing and maintaining probabilistic risk models and supporting thermal-hydraulic safety evaluations. The position offers the opportunity to work on next-generation nuclear technology while collaborating with reactor design, safety analysis, licensing, and systems engineering teams to ensure safe, reliable, and efficient plant performance.
Location: Camden, NJ (On-site)
Primary 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
Requirements:- 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
Compensation:- Annual compensation based on skills and experience ranging from $115,000 to $140,000
Benefits:- Industry-leading medical, dental, and vision coverage with a generous employer premium contribution and Day 1 eligibility!
- FLEX Program - Hybrid work opportunities available for eligible roles, where business needs and role requirements allow
- 401(k) retirement plan with up to a 5% company match and immediate vesting to support long-term financial security
- Paid time off and 11 paid holidays to support rest, balance, and recharge
- Wellness program offering rewards for participation in company-supported health initiatives
- Commuter benefits supporting mass transit and commuter parking options
- Company-paid life and AD&D insurance for added peace of mind
- Education assistance to support continued education and professional growth
- Employee support and voluntary benefits, including an Employee Assistance Program and optional coverage such as disability, legal, identity theft, and insurance programs
- Benefits eligibility and offerings may vary based on role, location, and employment status
