Thermal Fluids-CFD Analyst at TerraPower

Thermal Fluids-CFD Analyst

TerraPower Bellevue, WA Full-Time

TITLE:                Thermal Fluids-CFD Analyst

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 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. In addition, as a federal contractor, TerraPower has instituted an Affirmative Action Plan (AAP) in an effort to proactively recruit, hire, and promote women, minorities, disabled persons and veterans.   

Thermal Fluids/CFD Analyst

The Thermal Fluids Analyst contributes to the development of Computational Fluid Dynamics (CFD) methods to support flow and heat transfer behaviors directly supporting the Natrium sodium-cooled reactor. The analyst will also perform analyses supporting the design of the Natrium reactor and contribute to verification and validation of methods relevant to liquid metal fast reactors.

Responsibilities

  • Develops simulations of liquid metal/low Prandtl number flows in the heat transport systems using adequate models and best practices
  • Participates in the design and optimization of systems, structures, and components for performance and safety
  • Participates in the development of methodologies to support reactor safety and transient analyses
  • Consolidates data from the CFD simulations to develop reduced order-models for reactor thermal hydraulic analyses
  • Interfaces with other engineering groups performing aspects of component, system, fuel, and control system design and related thermal-hydraulic testing
  • Performs validations to establish best practices in the application of CFD methods to liquid metal flow and heat transfer in the reactor design
  • Perform analyses using first principles and fundamental Thermal hydraulics principles to evaluate designs and other thermal hydraulic behaviors for the Natrium reactor.

Key Qualifications and Skills

  • Advanced degree in nuclear engineering, or mechanical or chemical engineering with emphasis on nuclear systems
  • Experience with Thermal Hydraulic first principles and use of correlations to perform analyses and evaluations of designs and phenomena
  • 2 - 5 years experience with commercial CFD code STAR-CCM+
  • Knowledge of different modeling techniques with an ability to navigate the modeling choices relative to the objectives of a simulation and the computational resources
  • Experience in the development and application of CFD models to simulate nuclear systems or similarly complex thermal systems in coursework or research
  • Turbulent heat transport in low Prandtl number problems a plus
  • Knowledge of correlation development to be used in reduced order modeling tools
  • Experience with an object-oriented programming language (Java, Python, C++)
  • Strong technical writing skills
  • Effective communication skills
  • The successful candidate will possess a high degree of trust and integrity, communicate openly and display respect and a desire to foster teamwork
