About United Cleanup Oak Ridge (UCOR)
United Cleanup Oak Ridge (UCOR) is the Department of Energy’s lead environmental cleanup contractor for the Oak Ridge Reservation. As an award‑winning leader in nuclear environmental remediation and engineered facility operations, UCOR delivers safe, efficient, and innovative solutions to some of the nation’s most complex technical challenges.

In addition to major cleanup and decommissioning projects, UCOR performs critical nuclear operations at the Transuranic Waste Processing Center (TWPC) and the Liquid Gaseous Waste Operations (LGWO) facility at Oak Ridge National Laboratory. These systems require disciplined engineering, rigorous configuration management, and high‑consequence operational awareness—all foundational to UCOR’s technical mission.

Engineering at UCOR
UCOR engineers play a key role in enabling safe and compliant operations across environmental remediation, nuclear facility operations, engineered system design, waste processing, and mission‑critical infrastructure. Whether supporting ongoing cleanup, leading system modifications, developing engineered controls, or guiding field execution, engineers directly influence mission success and risk reduction across the Oak Ridge Reservation.

Why Work With Us
At UCOR, you’ll work in a collaborative environment where engineering rigor, safety, teamwork, and innovation are essential. We offer opportunities to solve unique technical problems, grow professionally, and contribute to nationally significant cleanup and nuclear operations missions.
