Senior Engineer, Consequence Safety Methods & Analysis

Senior Engineer, Consequence Safety Methods & AnalysisBellevue, WA, USATerraPower is a nuclear technology company based in Bellevue, Washington. At its core, the company is working to raise living standards globally through a more affordable, secure, and environmentally friendly form of nuclear energy along with innovations in medical isotopes to improve human health. In 2006, TerraPower originated with Bill Gates and a group of like-minded visionaries who evaluated the fundamental challenges to raising living standards around the world. They recognized energy access was crucial to the health and economic well-being of communities and decided that the private sector needed to take action and create energy sources that would advance global energy deployment. TerraPower's mission is to be a world leader in new nuclear technologies, while developing innovators and future leaders in the nuclear field. As a result, the company's activities in the fields of nuclear energy and related sciences are yielding significant innovations in the safety and economics of nuclear power, hybrid energy and medical applications – all for significant human health benefits.The Senior 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:Analysis of Licensing Basis Events (LBEs) With Radionuclide ReleaseMechanistic Source TermRadiological Release ConsequenceEmergency Planning ZoneThe Senior Consequence Safety Methods & Analysis 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 Senior Consequence Safety Methods & Analysis Engineer receives administrative, technical, and project supervision from the Consequence Safety Methods & Analysis Manager.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.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.
