About the role
- 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.
Responsibilities
- Develop, maintain, and enhance dynamic models of reactor systems, including primary sodium coolant loops, intermediate circuits, decay heat removal systems, and associated instrumentation & control (I&C) logic using FORTRAN, C++, and Python.
- Configure, maintain, and troubleshoot real-time simulation platforms (R*Time and RTP), and support integration with control room hardware, digital I&C, and interface systems.
- Collaborate with reactor design engineers, I&C engineers, training specialists, and human factors experts to ensure simulator fidelity across normal operations, transients, and off-normal conditions.
- Perform acceptance testing, validation, debugging, and model verification to ensure simulator behavior aligns with plant calculations, design basis events, and training needs.
- Support training sessions by diagnosing simulator issues, implementing corrective model actions, and minimizing downtime during training.
- Produce and maintain detailed engineering documentation, model descriptions, test records, and change logs in compliance with nuclear quality assurance (QA) standards and configuration control processes.
Requirements
- Occasional travel to plant design, training facilities, or vendor sites may be required.
