ATKINSREALIS JOINT VENTURE AWARDED US $2.3 BILLION CONTRACT TO OPERATE AND MAINTAIN U.S. DEPARTMENT OF ENERGY NUCLEAR ASSETS

Atkinsrealis Group Inc. is leading a joint venture, with partners Westinghouse Government Services and Jacobs Technology Inc., that has been awarded a 10-year contract to operate the depleted uranium hexafluoride (DUF6) conversion facilities and assume site landlord responsibilities at the United States Department of Energy's (DOE) Paducah and Portsmouth gaseous diffusion plants. A joint venture led by Atkinsrealis's U.S. nuclear team has been operating and maintaining the DUF6 facilities for the DOE Portsmouth Paducah Project Office (PPPO) since 2016.

"This work illustrates how our commitment to protecting the planet's environment and its people through our end-to-end services across the entire nuclear asset life cycle is a key differentiator for Atkinsrealis," said Ian L. Edwards, president and chief executive officer, Atkinsrealis. "We are dedicated to safely managing legacy nuclear materials and fostering economic growth that improves communities."

Under the 10-year $2.3-billion (U.S.) Operations & Site Mission Support Contract (OSMS), the joint venture known as Mission Conversion Services Alliance LLC (MCSA) will operate the DUF6 conversion facilities, transforming the inventory of DUF6 into a more stable uranium oxide (OUx) for disposition. MCSA will provide surveillance and maintenance services of the DUF6 cylinder inventory awaiting disposition and perform off-site disposal of empty cylinders as well as the depleted uranium oxide. MCSA will also provide protective security forces, emergency management and fire protection services, as well as operating and maintaining utilities at both plants.

"Through our long-standing partnership with the DOE, we've been continuously upgrading the DUF6 plants to make them safer and more reliable. We appreciate the DOE's confidence in us to continue our blueprint for plant improvements and increased production, as well as bringing this same continuous improvement management culture to the infrastructure and support scopes that are new to this contract," said Joe St. Julian, president, nuclear, Atkinsrealis.

"We are honoured to continue the safe execution of the PPPO's mission, and our team appreciates the opportunity to support this important mission in partnership with the DOE," said Jeff Kendall, president (interim), Atkinsrealis U.S. nuclear. "We are incredibly proud of the leadership team at DUF6 and the broader operational and support teams that have transformed the future of both the Paducah and Portsmouth plants to ensure the safe delivery of our present and future scope."

Atkinsrealis is a leading nuclear services company offering the full range of services for decommissioning and remediation of nuclear sites and facilities, management of spent nuclear fuel, the transportation of nuclear material, and environmental cleanup of nuclear legacy sites.
