TITLE: Senior Safety Analysis Engineer LOCATION: Bellevue, WA, USA TerraPower 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. TerraPower is seeking to hire a highly motivated and forward-thinking professionals who are interested in focusing on advanced nuclear reactor research and development and influencing change within the nuclear power landscape and bringing forward the critical production of medical isotopes. TerraPower is an Equal Opportunity Employer. We do not discriminate in hiring on the basis of sex, gender identity, sexual orientation, race, color, religious creed, national origin, physical or mental disability, protected Veteran status, or any other characteristic protected by federal, state, or local law.

Senior Safety Analysis Engineer The Senior Safety Analysis Engineer is part of a growing team supporting the design and licensing of the Natrium Demonstration reactor and is primarily responsible for performing Licensing Basis Events (LBE) analyses. The Senior Safety Analysis Engineer may also contribute subject matter expertise to other projects under development by the TerraPower Sodium Fast Reactor (SFR) Program. Responsibilities Depending on qualification and skills, perform transient analyses to meet the safety analysis needs of the Natrium Demonstration reactor for Anticipated Operational Occurrence (AOO), Design Basis Event (DBE), Design Basis Accident (DBA), and Beyond Design Basis Event (BDBE). Collaborate with safety methods development engineers to establish methods, computational models, and other aspects of the Evaluation Models. Work with an interdisciplinary team of engineers to establish SSC functional, performance, safety, and quality requirements as well as support the overall design. Establish and maintain documentation of model development and analysis. Perform engineering reviews of analyses and other engineering design media. Contribute, as needed, to the development of computational models supporting system modeling for design and operational transients as well as PRA. Contribute, as needed, to the assessment of the Evaluation Models against applicable tests and perform appropriate benchmark calculations. Key Qualifications and Skills B.S. or higher in nuclear engineering or other relevant engineering degree, with a minimum of 5 years of experience in the nuclear field. Knowledgeable of nuclear systems fundamentals such as thermal-hydraulic, neutronics, dynamics, and reactor transient behavior in general. Familiarity and experience with analysis of Anticipated Operational Occurrence (AOO), Design Basis Event (DBE), Design Basis Accident (DBA), and/or Beyond Design Basis Event (BDBE) is required. Expe
