Position Description: Protingent Staffing has an exciting*REMOTE*contract Principal Seismic Probabilistic Risk Assessment Engineer opportunity.
Job Responsibilities:- Manage SPRA work performed outside of the Company in coordination with plant design, deterministic safety analysis, and other disciplines.
- Ensure that the SPRA 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 (RG 1.233 and NEI 18-04) and ASME/ANS Non-Light Water PRA standard.
- Lead the development of the planning and schedule for SPRA-related activities.
- Provide technical guidance to engineers and managers on reliability and various SPRA-related topics.
- Participate in SPRA peer reviews.
- Review and support the development of event and fault trees for SPRA 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 containment fault trees and event trees to reflect the most up-to-date design using CAFTA.
- 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.
Job Qualifications:- B.S., M.S., or PhD in nuclear, mechanical, electrical, or aerospace engineering (or similar)
- Fifteen years or more of experience in Probabilistic Risk Assessment
- In-depth knowledge of PRA principles and the ASME/ANS Non-Light Water PRA standard.
- In-depth knowledge of risk-informed performance-based regulations and applications.
- In-depth knowledge of PRA fundamentals in data, human reliability, accident analysis, severe accidents, and source terms assessments.
- Experience with PRA software: CAFTA in particular; SAPHIRE, Risk Spectrum, or other similar software is still 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.
- 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.
