EnergySolutions Receives Nuclear Regulatory Commission Approval for the Three Mile Island Unit-2 Nuclear Power Plant (TMI-2) License Transfer and New Jersey BPU Approval for the Sale of the Facility

Salt Lake City, UT – December 02, 2020 – Today, the Nuclear Regulatory Commission (NRC) approved the transfer of the Three Mile Island Unit-2 Nuclear Power Plant and the corresponding Possession-Only license from FirstEnergy Corp. subsidiaries GPU Nuclear, Inc., Metropolitan Edison Company, Jersey Central Power & Light Company, and Pennsylvania Electric Company to a subsidiary of EnergySolutions known as TMI-2 Solutions, LLC. In addition to the NRC approval, the New Jersey Board of Public Utilities (BPU) today approved the sale of TMI-2 to TMI-2 Solutions, LLC.

FirstEnergy Corp and EnergySolutions submitted the request for the license transfer on November 12, 2019. The NRC and BPU review processes confirms that EnergySolutions meets all regulatory, legal, financial and technical requirements to acquire the NRC license and transfer the plant.

“This is a major milestone in the nuclear industry and for the central Pennsylvania region.” stated Ken Robuck, President and CEO of EnergySolutions. “We appreciate the thorough review of this request by the NRC and the New Jersey BPU with the understanding of the responsibility granted to EnergySolutions by both organizations to safely decommission the Three Mile Island Unit 2 Nuclear Power Plant.”

“We are excited for the opportunity to safely decommission Unit-2 at Three Mile Island and restore the area to its natural state,” added Robuck. “We currently have four decommissioning projects, two of which will be completed by the end of the year. These four projects have provided valuable experience with best practices and lessons learned that we will incorporate into this project.”

In 1979, TMI-2 experienced a partial meltdown which resulted in permanent closure of the facility. In the 1980’s, 99% of the nuclear fuel was removed from the plant, packaged and relocated to a storage facility at Idaho National Laboratory (INL). The TMI-2 facility has remained in a safe and stable storage condition known as Post Defueling Monitored Storage for the past 27 years.

To perform the decommissioning work on this project, EnergySolutions and Jingoli, a construction company headquartered in New Jersey, formed a joint venture called ES/Jingoli

Decommissioning, LLC. Jingoli successfully managed and executed nuclear projects on behalf of numerous utilities in the United States and Canada with experience in the nuclear field from pre-construction, construction management, project controls and decommissioning.
