About The Position

The Consequence Safety Methods Lead 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: Analysis of Licensing Basis Events (LBEs) With Radionuclide Release, Mechanistic Source Term, Radiological Release Consequence, and Emergency Planning Zone. The Consequence Safety Methods Lead Engineer may also contribute as a subject matter expert to other areas under development by the TerraPower Sodium-cooled Fast Reactor (SFR) Program. Other engineering activities include, but are not limited to, developing the safety methods, 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

M.S. or Ph.D. in nuclear engineering, or other relevant engineering degree, with at least 10+ years of experience in the nuclear field. (an M.S. degree counts as 1 year of experience and a Ph.D. degree may count as up to 3 years of experience with a demonstrated ability to produce a high-quality work product)
Knowledgeable of nuclear systems thermal-hydraulic, fuel performance, reactor dynamics, accident source term, and transient phenomena.
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 required.
Familiarity with EMDAP and RG 1.203 is required.
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.

Nice To Haves

Experience directly interacting with the US NRC on design and analysis methodology applications, such as licensing topical report(s), is strongly preferred.
Experience with source term and radiological consequence codes is highly desirable.
Experience with source term methods development is highly desirable.
Experience with SFR safety methods is highly desirable.
Experience with other reactor designs can be considered when differentiating candidates.
Strong communication skills are desired

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 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.
