- Perform focused PRA analysis to support trade studies.
- Prepare topical reports describing PRA methods and analytical results for customers and regulators.
- Provide technical guidance to engineers and managers on reliability and various PRA-related topics.
- 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.
- Participate in the development of planning and scheduling for PRA related activities.
- 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.
- Contribute to the PRA work performed inside and outside of TerraPower in coordination with plant design, transient and consequence safety analysis, and other disciplines.
- Deliver presentations for internal management and external customers and regulators.
- Develop fault trees and event trees to reflect most up to date design using CAFTA.
- Perform engineering reviews of analyses and other engineering design media.
- Perform hand calculations using first principles to assess and validate more complex models for system performance, containment performance, and radiological consequences.
- Participate in PRA peer reviews.
- Establish and maintain documentation of model development and analysis results.
- Perform risk integration using the PRA model to report risk metrics and importance measures.
- 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.
- Group similar source terms for assignment to event sequence end states.
