EnergySolutions Files Lawsuit Against Kurion Inc. Seeking Punitive Damages and an Injunction on Sales of Products and Services

SALT LAKE CITY, UT--(Marketwire - Mar 6, 2013) - EnergySolutions, Inc. (NYSE: ES) today announced that it and an affiliate, EnergySolutions Diversified Services, Inc. formerly known as Nukem Corporation, (collectively "EnergySolutions") filed a lawsuit against Kurion Inc. and two former EnergySolutions employees now employed by Kurion to enforce contractual and intellectual property rights related to EnergySolutions' waste treatment and vitrification technologies. The lawsuit was filed in the Third Judicial District Court in and for Salt Lake City, Utah. EnergySolutions seeks monetary and punitive damages, and asks the court to enjoin further sales of all Kurion products and services that utilize or derive from the confidential and proprietary technology misappropriated from EnergySolutions.

EnergySolutions, a world leader in nuclear decommissioning and remediation with more than 100 patents and patent applications, filed the case against Kurion, a direct competitor of EnergySolutions, alleging misappropriation of EnergySolutions' intellectual property and unlawful claim of ownership. The specific technologies involve, among others, the ability to remove radioactive isotopes from an aqueous waste stream using isotope specific media, and the ability to vitrify the separated isotopes with the media to immobilize the waste in a leach-resistant glass matrix for long term environmental isolation.

"Our intellectual property rights are core assets that have positioned EnergySolutions as an industry leader," said David Lockwood, President and CEO of EnergySolutions. "We are committed to protecting the significant investments we have made into our innovative technologies. We will pursue former employees who misappropriate EnergySolutions proprietary technologies."

EnergySolutions believes it has discovered substantial evidence that Kurion and two of its employees, John M. Raymont, Jr. and Mark S. Denton, misappropriated and are using, marketing and disclosing EnergySolutions' confidential and proprietary technology in violation contractual obligations, fiduciary duties and intellectual property laws. Raymont and Denton were former EnergySolutions executive-level employees prior to joining Kurion.

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.
