Job Overview

System One is seeking a Senior Safety Methods Engineer to perform design and licensing analyses and develop associated methodologies in the following areas:

• Developing methods for design and licensing basis events
• Modeling of fuel failure and core degradation
• Performing transient and accident analyses

The Senior Safety Methods Engineer may also contribute subject matter expertise to other projects under development by our client’s Sodium‑cooled Fast Reactor (SFR) Program. Other engineering activities include, but are not limited to, performing accident analyses, contributing to software qualification, participating in hazard analysis, participating in Structures, Systems and Components (SSC) classification, as well as performing verification and validation activities.

Tasks

• Develop methodologies using a graded approach to the Evaluation Model Development and Assessment Process (EMDAP).
• Develop assessment bases (benchmark, identify applicable tests, etc.) and assess the evaluation model.
• Develop analytical and computational models in collaboration with safety analysis engineers.
• Perform transient and accident analyses to meet the safety analysis needs of the (SFR) program.
• Work with an interdisciplinary team of engineers to establish core and SSC functional, performance, safety, and quality requirements, as well as support the overall design.
• Establish and maintain analysis of record and methodology documentation.
• Perform engineering reviews of analyses and other engineering design media.
• Contribute, as needed, to the implementation of capabilities required for transient and accident analysis within the TerraPower software framework.

Key Qualifications and Skills

• M.S. or Ph.D. in nuclear engineering, or other relevant engineering degree, with at least 10+ years of experience in the nuclear field.
• Knowledgeable of nuclear systems thermal-hydraulic, fuel performance, reactor dynamics, accident source term, and transient phenomena.
• Experience directly interacting with the US NRC on design and analysis methodology applications is strongly preferred.
• Significant experience with transient and accident analysis codes is required.
• Familiarity with nuclear design, regulatory requirements, and risk‑informed performance‑based technology guidance for Non-Light Water Reactors under Regulatory Guide (RG) 1.233 is strongly preferred.
• Familiarity with EMDAP and RG 1.203 is required.
• Experience with SFR safety methods is highly desirable. Experience with other reactor designs can be considered when differentiating candidates.
• Demonstrated strong quantitative, analytical, modeling, and reporting skills.
• Understanding of Appendix B to 10 CFR 50 and ASME NQA-1 requirements associated with analysis and software management, as well as experience working under a quality assurance program.
• Experience in working in multi-disciplinary engineering teams to address engineering challenges.
• Strong communication skills are desired.
• The candidate will possess a high degree of trust and integrity, communicate openly and display respect, and a desire to foster teamwork.
