UCOR is also engaged in cleanup and waste management activities at the Oak Ridge National Laboratory and the Y-12 National Security Complex. UCOR is a partnership of URS and CH2M HILL, and its team subcontractor Restoration Services, Inc. is one of Oak Ridge's most successful woman-owned small businesses. 

WAI is a Small Business Administration Certified 8(a) small disadvantaged business headquartered in Piketon, Ohio. In Oak Ridge, WAI operates the Transuranic Waste Processing Center for the Environmental Management program. The company is responsible for all aspects of operations at the facility, including the processing, packaging, and shipping of all remote-handled and contact-handled transuranic waste. Additionally, WAI processes, treats, and prepares low-level and mixed low-level radioactive waste, and hazardous or industrial waste, for disposal.
