Probabilistic Safety Analysis Engineer – New Nuclear

We are supporting a major nuclear operator in the US on the development and delivery of advanced reactor technologies based at Columbia Generating Station in Richland, WA. This is a long-term onsite contract (1 year+) offering the opportunity to contribute directly to new nuclear projects, including design, licensing, and construction activities within a highly regulated environment. The role focuses on delivering complex Probabilistic Safety Analysis (PSA/PRA) activities, supporting both existing operations and next-generation reactor programmes.

Key Responsibilities: Perform complex PSA/PRA analyses including hazard analysis, consequence evaluation, and defense-in-depth assessments Support Owners Engineer activities across design, licensing, and construction phases of advanced reactor projects Participate in design reviews and provide technical input on new nuclear technologies and progressive design/build programmes Interpret and apply regulatory requirements (NRC), as well as industry guidance (NEI, EPRI, ASME/ANS standards) Develop and review PSA models, including initiating events, event sequences, and uncertainty/sensitivity analyses Provide schedule inputs and support project planning activities Identify design, operational, or quality issues and initiate corrective actions Provide technical leadership, mentoring, and guidance to junior engineers Support development of procedures, programmes, and engineering policies aligned with strategic objectives Requirements: Engineer I: Bachelor's degree in Engineering 1+ year of relevant experience Engineer II: Bachelor's degree in Engineering 3+ years of relevant experience Engineer III: Bachelor's degree in Engineering 7+ years of relevant experience (PE license may be considered in lieu of degree requirements as per experience level) Desired Experience & Skills: Experience with PSA/PRA methodologies and standards (ASME/ANS RA-S-1.4) Strong background in PRA model development, including initiating events, event sequences, and quantitative analysis Knowledge of transient and accident analysis, including source term evaluation Experience interpreting PSA results and applying them to engineering decisions Familiarity with Seismic and Fire PRA Exposure to advanced reactor technologies (e.g.

HTGR or similar designs) Experience supporting large-scale nuclear construction projects Familiarity with NEI guidance (e.g. NEI 18-04) Ability to work independently and provide technical leadership on complex engineering challenges Gintare Juozapaviciute
