The Princeton Plasma Physics Laboratory currently uses two (2) large, stored energy, Motor-Generators, each Generator rated at 450 MVA, to supply power to the various experimental loads in support of National Spherical Torus Experiment - Upgrade (NSTX-U) operations. Each motor-generator is driven by a 15,000 horsepower (HP) electrical induction motor rated at 13.8 KV.The motor-generator technician will provide support for all maintenance, testing, repairs, upgrades, installations, modifications and troubleshooting of the motor generators and their associated subsystems.A proud U.S. Department of Energy National Laboratory managed by Princeton University, Princeton Plasma Physics Laboratory (PPPL) is a longstanding leader in the science and innovation behind the development of fusion energy — a clean, safe, and virtually limitless energy source. With an eye on the future and in response to national priorities, PPPL also has begun a strategic shift from a singular focus on fusion energy to a multi-focus approach that includes microelectronics, quantum information science, and sustainability science. Whether it be through science, engineering, technology or professional services, every team member has an opportunity to make their mark on our world. PPPL aims to attract and support people with a rich variety of backgrounds, interests, experiences, and cultural viewpoints. We are committed to equity, diversity, inclusion and accessibility and believe that each member of our team contributes to our scientific mission in their own unique way.
