TITLE: Primary Heat Transport System Design EngineerLOCATION: Bellevue, 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.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.Primary Heat Transport System Design EngineerThe Primary Heat Transport (PHT) System Design Engineer is focused on the primary sodium heat transport system design as part of the Natrium sodium fast reactor. The PHT is analogous to the nuclear steam supply system in a light water reactor. In this role, you will act as a system design engineer for TerraPower's advanced nuclear reactor projects or other highly technical projects. The successful candidate demonstrates in depth knowledge of fluid system design including knowledge of centrifugal pump and tube & shell heat exchanger operation. The PHT System Design Engineer will work as part of a high-performing team of engineers and scientists.ResponsibilitiesDesign of nuclear and industrial process systems and sub-systems from requirements through final design.Perform an array analysis in support of design (thermal-hydraulic, structural, etc.) using a combination of hand calculation and software-based methods.Identify and ensure effective application of correct design codes into the design of plant systems such as ASME, ANS, ASTM, IEEE, NFPA, etc.Provide technical direction and guidance to engineers in applicable nuclear and non-nuclear related design standards.Analyze and allocate regulatory criteria and standards to complex mechanical and process system design.Support planning efforts and maintain schedule adherence for design activities within a system, as well as their integration with an overall plant design delivery schedule.Interface with the design team to create and manage drawing packages of system designs, including but not limited to Piping and Instrumentation Diagrams (P&IDs), 3D models, and system interface drawings.Interface with design disciplines (such as mechanical, instrumentation and controls, civil, and nuclear) to identify and develop plant design information and specify system design and performance criteria.Provide technical direction and oversight of supplier projects, working with the contract administrator to ensure delivery of data and other deliverables, as well as coordination and performance of technical reviews of deliverables.Establish and maintain system requirements and specification documents, such as Engineering Design Specifications for major plant equipment.Propose and initiate testing programs for plant system qualification, as needed.Provide Support and oversight during test execution, evaluati
