TerraPower Tech Stack

Advanced nuclear reactor design and radioisotope production for energy and medical applications

Nuclear Electric Power Generation Bellevue, WA 501–1,000 employees Privately Held

TerraPower develops next-generation nuclear reactors and medical radioisotope production systems. The tech stack—anchored in HPC, FORTRAN, C++, and Palantir for simulation and data integrity—reflects a physics-heavy engineering operation. The hiring profile is overwhelmingly engineering-focused (57 of 95 roles), with active projects spanning reactor design, testing, and isotope production facilities. Pain points cluster around production scaling, regulatory compliance, and partnership formation, signaling the operational complexity of moving advanced nuclear from R&D into real-world deployment.
