TITLE: Natrium Methods Qualification Lead 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. Natrium Methods Qualification Lead The Methods Qualification Lead is responsible for creating and overseeing the execution of plans to qualify methods for use in safety-related thermal hydraulic transient analysis. These plans will cover the elements described in NRC Regulatory Guide 1.203, with an emphasis on Element 2 ("Develop Assessment Base") and Element 4 ("Assess Evaluation Model Adequacy"). The Methods Qualification Lead serves as the technical liaison between organizations at Natrium performing thermal hydraulic methodology development and test suppliers. They will ensure that sufficient test data is provided to close gaps in the validation and applicability bases, in a manner that balances Natrium project schedule, cost, and risk. This position reports to Natrium's Director of Safety and Engineering Analysis. Responsibilities Ensure procedural framework for use of software in design and analyses and test control are in accordance with TerraPower's QA Program and associated procedures. Provide stakeholder review of engineering methodology documents pertaining to the validation and applicability basis of software used in safety analysis, to assist in identifying applicability basis gaps and support incorporation into test planning. Ensure the project maintains an up-to-date planning document to identify gaps in the validation bases of safety-related thermal hydraulic analyses, and how they will be addressed by separate effects, integral effects, component qualification or production, environmental qualification, hot functional, or initial criticality testing. Ensure that testing needs and requirements are approved to support development of experimental testing to provide data to complete the applicability basis and validation needs. Plan and support the development of engineering work pertaining to scaling, pre-test predictions, post-test analyses related to all verification of testing requirements. Review and owner accept any deliverable that affects implementation of test requirements related to facility design, commissioning, or test execution. Help to define and provide technical oversight for testing activities such as inspections or hold points related to verification of test design requirements. Provide technical oversight throughout the testing campaign to ensure data collected will meet validation needs. Support selection, procurement and qualification of applicable legacy test data.
