Oak Ridge, TN.: January 27, 2025 – AtkinsRéalis, a fully integrated engineering services and nuclear company with offices around the world, announces that its US Nuclear business has formed StAR, a mentor-protégé joint venture (JV) with Strata-G LLC that will focus on tapping strategic contract opportunities at the federal level and in various commercial markets.
StAR combines AtkinsRéalis’ global nuclear, engineering and program management capabilities with Strata-G’s regional professional services expertise to support various missions for the U.S. Department of Energy (DOE) as well as other federal government agencies and commercial customers. Through a U.S. Small Business Administration (SBA) program1, designed to help small businesses compete for federally procured opportunities more effectively, AtkinsRéalis will leverage its vast government contracting experience and provide mentorship and assistance to Strata-G under a six-year mentor-protégé agreement.
“By combining our companies’ strengths, we can provide our clients with the absolute best suite of comprehensive services in the industry,” said Joe St. Julian, President, Nuclear, AtkinsRéalis. “While the synergies between our cultures, values and services, made this mentor-protégé relationship a natural fit.”
AtkinsRéalis US Nuclear business has successfully addressed some of the industry’s most challenging cleanup and decommissioning tasks for three decades. During this time, clients have benefitted from the Company’s process design engineering, waste management, characterization, transportation, disposition and high-level waste technologies expertise.
“This collaboration allows us to continue working with an exceptional partner, while leveraging contract models that would otherwise not have been available to us,” said Jeff Kendall, Interim President, AtkinsRéalis US Nuclear.
Strata-G has been a key subcontractor to AtkinsRéalis subsidiary Isotek Systems, LLC since 2003. Isotek Systems is executing the Oak Ridge U-233 Disposition contract for DOE2. Based in Tennessee, Strata-G specializes in providing waste management, environmental compliance, radiological and nuclear operations, safety, industrial hygiene, transportation, engineering and project management services.
