Probabilistic Risk Engineer II

Holtec International seeks qualified applicants in its Probabilistic Safety Analysis (PSA) discipline. The PSA Engineer II will join a multidisciplinary team of engineers engaged in designing Holtec's flagship nuclear reactor SMR-300 managed by SMR, LLC, which is a subsidiary of Holtec International. Holtec International a global turnkey supplier of equipment and systems for nuclear, solar, geothermal, and fossil power generation sectors of the energy industry.

Primary Responsibilities:

• Develop and maintain PRA logic models and/or supporting thermal-hydraulic analyses used to quantify risk and support design and licensing activities.
• 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 used to quantify 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)
• Proficiency with one or more industry codes such as CAFTA, SAPHIRE, RiskSpectrum, RELAP5-3D, or MELCOR
• 4-6 years of experience in probabilistic risk assessment and/or thermal-hydraulic safety analysis for nuclear facilities
• Familiarity with ASME/ANS PRA Standards and NRC or IAEA risk guidance  
• Ability to interpret results and communicate risk insights clearly to technical audiences
• Excellent technical writing, interpersonal, and communication skills
• Eligible to work under 10 CFR Part 810
