Criticality Safety Engineer, Fuel

Terra Power 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, Terra Power 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. Terra Power’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.

Terra Power 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.

Terra Power is seeking a Criticality Safety Engineer to join the Natrium Fuel Design and Supply team. The Criticality Safety Engineer is responsible for developing, implementing, and maintaining nuclear criticality safety analyses and controls supporting the fabrication of Natrium fuel. The Criticality Safety Engineer will integrate criticality safety into facility and process design and will be involved with process development, production readiness, technical documentation, and supplier coordination.

This role requires quality-driven execution for safety critical components and fabrication processes.

• Develop nuclear criticality safety evaluations for fuel fabrication process steps, fresh fuel receipt, storage, handling, inspection, and transportation operations.
• Perform criticality safety calculations using industry-standard computational tools (i.e. SCALE/KENO, MCNP, etc) for Natrium fuel fabrication and related processes, including areas related to HALEU feedstock, fuel fabrication, and fresh fuel storage and transportation.
• Establish engineered and administrative controls to ensure subcriticality under normal, abnormal, and credible accident conditions.
• Develop and maintain Criticality Safety Evaluations, Criticality Safety Limits, and supporting technical documentation.
• Support design reviews to ensure equipment, storage configurations, fuel fabrication processes, and facility layouts satisfy criticality safety requirements.
• Evaluate design changes through engineering change processes and assess impacts to nuclear criticality safety.
• Support licensing activities by preparing technical
