EnergySolutions Pleased With Court's Ruling

SALT LAKE CITY, UT--(Marketwire - May 15, 2009) - EnergySolutions, Inc. (NYSE: ES) announced today that the U.S. District Court for the District of Utah ruled that the Northwest Compact lacks authority to restrict EnergySolutions' receipt of waste generated outside the Compact region. In May 2008 EnergySolutions sought clarification from the court and today the court agreed with the company's interpretation of the law on this critical issue.

"We have always felt confident in our legal position and appreciate the thoroughness of Judge Stewart's decision in this case," said Steve Creamer, CEO and Chairman of EnergySolutions. "Our Clive, Utah disposal facility is a private commercial facility that is licensed by the State of Utah under delegated authority by the Nuclear Regulatory Commission. We are pleased that this ruling ends any question on this matter."

The Clive facility has been safely disposing of low-level material for over 20 years and has been disposing of residuals from internationally generated material for more than eight years. The Northwest Compact has never voiced an objection to the Clive facility's disposal of this material until recently.

EnergySolutions offers customers a full range of integrated services and solutions, including nuclear operations, characterization, decommissioning, decontamination, site closure, transportation, nuclear materials management, processing, recycling, and disposition of nuclear waste, and research and engineering services across the nuclear fuel cycle.
