Consequence Safety Methods & Analysis Engineer

TerraPower•Bellevue, WA

About The Position

The Consequence Safety Methods & Analysis Engineer is part of a growing team supporting the design and licensing of the Natrium® demonstration reactor and is primarily responsible for performing methodology development and safety analysis in the following areas: • Licensing Basis Events (LBEs) with Potential Radionuclide Release • Mechanistic Source Term • Radiological Release Consequence • Sodium Chemical Reaction The Consequence Safety Methods & Analysis Engineer may also contribute as a subject matter expert to other projects under development by the TerraPower 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. Under the TerraPower SFR Program, the Consequence Safety Methods & Analysis Engineer receives administrative, technical, and project supervision from the Consequence Safety Methods & Analysis Manager.

Requirements

Knowledge of nuclear systems thermal‑hydraulics, fuel performance, reactor dynamics, accident source term analysis, and transient phenomena
Proficiency with transient and accident analysis codes
Experience with source term and radiological consequence analysis codes
Experience in safety analysis methods development
Experience with SFR safety analysis methods; experience with other reactor designs may also be considered
Familiarity with nuclear design, regulatory requirements, and risk‑informed, performance‑based technology guidance for Non‑Light Water Reactors under Regulatory Guide (RG) 1.233
Knowledge of Appendix B to 10 CFR 50 and ASME NQA‑1 requirements related to analysis and software management, with experience working under a quality assurance program
Strong quantitative, analytical, modeling, reporting, and communication skills
Experience collaborating on multidisciplinary engineering teams to address complex engineering challenges
Demonstrated integrity, open communication, respect for others, and a commitment to fostering teamwork

Responsibilities

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 design and 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, and support the overall design.
Establish and maintain analyses-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.
