Under the terms of the agreement, the alliance will provide a single contracting group to manage and deliver their decommissioning projects for their customers.

Bechtel global environmental business general manager Michael Graham said: "Customers can trust that Bechtel and Westinghouse will provide integrated services and solutions to safely decommission, decontaminate, and dismantle a power plant, and prepare the site for other uses.

"In the United States, the average age of commercial reactors is some 33 years, and many are approaching the end of their licensing periods."

In addition to focusing on the safe and efficient handling of radioactive materials, the alliance will provide a full range of services which include pre-shutdown planning, licensing, project development and management, dismantling, demolition, waste handling, and site closeout.

Westinghouse Americas president Mark Marano said: "Westinghouse is pleased to join with Bechtel to bring about the most fully-integrated range of decontamination and decommissioning services available to the U.S. nuclear energy market.

"The deployment of consolidated, proven technologies and processes from this alliance will meet the needs of U.S. nuclear power plants that are coming off-line, ultimately allowing the opportunity to return the land to useable property."
