Responsibilities:

• Contribute to PRA work performed inside and outside the organization in coordination with plant design, safety analysis, and other engineering disciplines

• Develop fault trees and event trees using CAFTA to reflect the most current plant design

• 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 analyses to support trade studies

• Work with the interdisciplinary team to establish SSC functional, reliability, performance, safety, and quality requirements

• Ensure PRA work is appropriate and compliant with regulatory requirements including NEI 18-04 and the ASME/ANS Non-LWR PRA standard

• Prepare topical reports and presentations describing PRA methods and analytical results for management, customers, and regulators
