TITLE: System Analysis Lead Principal Engineer

LOCATION: Bellevue, WA

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 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.

• Identify and resolve cross-functional technical challenges and risks. Provide technical direction and oversight of technical activities.

• Coordinate with cross-functional teams to integrate Safety Analysis of Licensing Basis Events (LBE) and ASME Design Transients into thermal loading specification.

• Coordinate with cross-functional teams to integrate Plant Performance Analysis (operation margin, confirmation of operations and commercial performance) with design, operations and simulator.

• Check and review RELAP5-3D models for steady state and transient one-dimensional network hydraulic analyses.

• Check, and review calculations using first principles of heat transfer, fluid dynamics, and thermodynamics to support and validate analysis results.

• Check and review analysis of reactor normal operations, upset events, emergency events and faulted events as defined in the ASME BPVC Section III to establish design, service, and test loadings from thermal hydraulic design basis events.

• Check and review analysis of plant wide transients for evaluation of operation margins, operation narratives and confirmation of design solutions for plant and system requirements.

• Check and review multiscale and multidisciplinary neutronics and control analyses involving the thermal hydraulics of sodium, molten salt, and non-condensable fluids.

• Check and review code benchmarking and validation analyses to support code qualification and methodology development.
