Principal Probabilistic Risk Assessment Engineer

Job Title: Principal Probabilistic Risk Assessment Engineer
Location: Remote

Type: Contract (yearlong)
Compensation: $102 - $130 hourly
Contractor Work Model: Fully Remote

System One is hiring a Principal Probabilistic Risk Assessment (PRA) Engineer with at least 15 years of experience for a long-term, fully remote contract position. The PRA Engineer will work with the Risk Assessment team and is responsible for performing PRA and severe accident analysis for our client's reactor design. The PRA Engineer is primarily responsible for internal and external PRA work to be performed in coordination with deterministic and consequence safety analysis and other engineering disciplines to design a reliable and safe plant. Additionally, the PRA Engineer will use developed PRA models to provide risk information such as importance measures and changes in risk metrics to inform design and licensing decisions. Other engineering activities include, but are not limited to, contributing to the development of computational methodologies and models, participating in hazard analysis, participating in Phenomena Identification and Ranking Table (PIRT) exercises, and participating in Structures, Systems, and Components (SSC) classification, Licensing Basis Events (LBE) selection, and Defense-in-Depth (DID) Evaluations. The PRA Engineer will be interacting with other groups via interviews, emails, meetings, and other avenues to develop risk models. The candidate will have sound written and verbal communication skills.

Responsibilities

• Contribute to PRA work performed inside and outside of our client in coordination with plant design, deterministic and consequence safety analysis, and other disciplines.
• Ensure that the PRA is appropriate and used for the reactor design and within regulatory requirements, guidance, and standards such as risk-informed performance-based technology guidance for Non-Light Water Reactors (NEI 18-04) and ASME/ANS Non-Light Water PRA standard.
• Participate in the development of planning and scheduling for PRA related activities.
• Provide technical guidance to engineers and managers on reliability and various PRA-related topics.
• Participate in PRA peer reviews.
• Work on the development of event and fault trees, in-vessel radiological transport models, containment transport models, and mechanistic radiological release categories for PRA models.
• Work with an interdisciplinary team of engineers to establish core and reactor SSC functional, reliability, performance, safety, and quality requirements as well as support the overall design.
• Establish and maintain documentation of model development and analysis results.
• Perform engineering reviews of analyses and other engineering design media.
• Develop fault trees and event trees to reflect most up to date design using CAFTA and FRANX.
• Group similar source terms for assignment to event sequence end states.
• Perform risk integration using the PRA model to report risk metrics and importance measures.
• Perform focused PRA analysis to support trade studies.
• Perform hand calculations using first principles to assess and validate more complex models for system performance, containment performance, and radiological consequences.
• Prepare topical reports describing PRA methods and analytical results for customers and regulators.
• Deliver presentations for internal management and external customers and regulators.

Key Qualifications and Skills

• B.S., or M.S. in nuclear, mechanical, electrical, or aerospace engineering (or similar).
• Fifteen years or more of experience in Probabilistic Risk Assessment.
• Knowledge and experience of External Events PRA are preferred.
• Knowledgeable of PRA principles and familiar with the ASME/ANS Non-Light Water PRA standard.
• Knowledge of risk-informed performance-based regulations and applications.
• Knowledgeable of PRA fundamentals in data, human reliability, accident analysis, severe accidents, and source terms assessments.
• Experience with PRA software: CAFTA and FRANX in particular; SAPHIRE, Risk Spectrum, or other similar software is considered valuable.
• Experience with performing assessments using codes such as GOTHIC, MELCOR, RADTRAD, or similar tools is a plus.
• Demonstrated technical writing and communication skills.
• Experience with sodium cooled reactors or other advanced reactors preferred.
• Fluent in spoken and written English language.
• A broad understanding of the various engineering disciplines and how they interrelate in the design of a Nuclear Power Plant.
• High degree of trust, integrity, open communication, respect for others, and teamwork.
