Following the TMI-2 accident in 1979, approximately 99 percent of the fuel and damaged core debris was removed from the reactor vessel and associated systems and shipped to DOE’s Idaho National Laboratory. Since 1993 when the initial cleanup of the plant was completed, TMI-2 has been in a condition known as Post Defueling Monitored Storage (PDMS). The plant is safe, stable and is being monitored.

TMI-2 Solutions’ parent company, EnergySolutions, Inc. is a global leader in nuclear reactor decommissioning. EnergySolutions provides high-level waste management, spent fuel handling and transportation, and complex decontamination and decommissioning services, including the decommissioning of commercial nuclear power generation facilities. TMI-2 Solutions is wholly owned subsidiary of EnergySolutions.TMI-2 Solutions has been established for the purpose of maintaining and decommissioning TMI-2 in the best interest of the community and the environment.

There are a number of significant benefits to proceeding with the decommissioning now instead of waiting. They include: taking full advantage of the knowledge and experience of subject matter experts familiar with the 1979 accident and that participated in the initial cleanup who are still available but will soon be retired; leveraging the significant technological advancements have occurred in the last 30 years, many resulting from the Fukishima Diachi accident recovery that can now be applied to TMI-2; removal of more than 90 percent of the radioactive waste and disposing of it in an engineered licensed disposal facility and safely packaging the remainder of the radioactive material in high integrity storage canisters for eventual shipment to a DOE facility enhances safety; removal of plant structures that are more than 40 years old and showing signs of degradation is more protective of the environment; and progressing the decommissioning now creates good jobs locally that can help offset the loss of jobs from the recent closure of TMI-1.

EnergySolutions decommissioning both units would be the most efficient approach. We recently completed a similar two-unit project at the Zion Nuclear Plant in Illinois and are performing another two-unit project at San Onofre in California. However, if Exelon retains ownership of TMI-1 we will work closely with Exelon to minimize any impacts between the two projects.

We finalized the deal to purchase TMI-2 from First Energy on Dec. 18, 2020 after we received approval from the U.S. Nuclear Regulatory Commission to transfer the nuclear license to us.

EnergySolutions has completed the physical decommissioning of the Zion Nuclear Plant in Illinois, the largest nuclear decommissioning project completed in the U.S as well as the La Crosse Nuclear Plant in Wisconsin. In addition, the company is in the process of decommissioning the Ft. Calhoun Nuclear Plant in Nebraska and the San Onofre Nuclear Generating Station in California. We will bring the extensive experience and lessons learned from these projects to TMI-2.

We have experienced staff and decommissioning subject matter experts who are currently available due to the recent completion of the Zion and LaCrosse decommissioning projects that can be deployed to TMI-2 enhancing the execution of the project. Also, progressing with decommissioning now removes the facility and its radioactive components and achieves a timely site restoration which is a more desirable status for the site and the community.

Yes, EnergySolutions will guarantee that no additional ratepayer/ taxpayer funds are needed to complete the Unit 2 decommissioning.

Yes, the decommissioning of TMI-2 will be different and we are planning accordingly. Initially we will keep the plant in PDMS for a period of about 1.5 to two years while we perform the necessary engineering, licensing, and project planning actions necessary to begin the decommissioning safely. The first phase of the decommissioning will involve safely removing and packaging the remaining one percent (about 2,500 pounds) of damaged core debris from the plant. This process will involve using remote technologies and robotics. It will be a well-controlled process with safety as the overriding consideration. When completed, TMI-2 will be in a condition similar to a normal nuclear plant. At that point the final phase of the decommissioning will be done which involves removing the plant structures including the cooling towers and completing the TMI-2 site remediation.

We estimate that after we transition from PDMS that it will take about 7 to 8 years to remove and package the damaged core debris from the plant and perform other decontamination work to place the plant in a normal condition. After that we expect it will take about another 7 to 8 years to dismantle the plant. At this point we expect the entire project to be completed in 2037. This is 17 years earlier than the current schedule. Please keep in mind these are estimates and could change as we complete the detailed planning.

If a company such as EnergySolutions assumes the full risk of the project with no future access to ratepayer funding to cover the costs of project overruns, then it is appropriate that such companies should be allowed to retain any underruns that may exist at the completion of the project.

There will be no new risks to the public health and safety from the decommissioning project. We will implement robust industrial safety and radiological controls during the work to protect the workers, public and the environment. On-site and off-site environmental monitoring will be performed in accordance with local, state and federal requirements, including continued monitoring by the Pennsylvania Department of Environmental Protection. Results of the monitoring will be made public

The Reactor Building was successfully entered after the accident and TMI-2 Solutions will carefully plan for further entries, supporting demolition and waste removal planning and operations. The plans will be done with worker safety as the highest priority. The TMI-2 decommissioning will be completed in accordance with strict worker exposure limits set by the U.S. Nuclear Regulatory Commission.

TMI-2 Solutions is working with the Pa. Department of Environmental Resources (PADEP) and other state agencies to ensure we are total compliance with all applicable regulations and permits. In addition, TMI-2 Solutions will keep PADEP updated regularly on the status of decommissioning.

Releasing the site for unrestricted use means the site radiological contamination will have been removed to the point the NRC no longer requires restrictions to protect the public. Note that a small portion of the site will still be restricted while small amounts of core debris remain in an Independent Spent Fuel Storage Installation until DOE retrieves it.

EnergySolutions is a company that performs decommissioning and radiological waste management as a core business. The acquisition of a shutdown nuclear plant transfers both the risks (potential cost overruns) and potential upside (cost underruns) to the purchaser.

The projected cost to decommission TMI-2 by 2037 is anticipated to be $1.06 billion (in 2019 dollars). The current funds in the existing TMI-2 Nuclear Decommissioning Trust (NDT) fund provide adequate funding for decommissioning when accounting for fund growth over the decommissioning term.

Currently there is approximately $877 million in the NDT. Accounting for fund growth over the term of the decommissioning the fund will be sufficient to complete the project. Moreover, TMI-2 Solutions will have access to additional decommissioning funding assurance instruments worth up to $100 million dollars throughout the most critical phases of the project, as well as a Parent Guarantee for the duration of the project.

The decommissioning will be done in various stages each involving a different number of workers. We expect at its peak that the project will employ between 200 and 300 people. Our intention is to hire as many local workers as possible and to maximize the services and support of qualified local vendors and contractors.

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.

All of the low-level radioactive waste will be shipped to our waste disposal facility in Clive, Utah. Some material may be sent to a facility in Texas. The damage core debris will be packaged in high-integrity storage cannisters similar to those used for normal spent nuclear fuel. Because the federal government has not licensed a centralized storage facility, the cannisters will be stored on site along with spent nuclear fuel from TMI-1. This is the case with all nuclear power plant sites in the U.S. Once the government fulfills its promise to have a centralized storage facility in operation the cannisters will be sent there.

Yes. The damaged core debris will be stored in a high-integrity storage cannisters in a specially designed facility known as an Interim Spent Fuel Storage Installation (ISFSI). This facility will have full-time security and will be engineered and designed to be protected from natural events. Most nuclear plants in the U.S. have similar facilities. These facilities are regulated and licensed for use by the U.S. Nuclear Regulatory Commission.

It is most efficient to decommission both interconnected units at the same time. However, if Unit 1 chooses to remain in long-term SAFSTOR, then we have a plan in place to decommission Unit 2 separately. However, the Unit 2 portion of the site would not be available for future use until Unit 1 is decommissioned.

The low-level waste will be shipped by rail and truck. Low-level radioactive waste shipments are under strict regulations set by the U.S. Nuclear Regulatory Commission and by federal and state transportation agencies. EnergySolutions is the most experienced transporter of radioactive material in the US and safety is our number one priority. People are not expected to be exposed to radiation during the shipments due to the packaging and other safety precautions.

There will need to be further evaluations, surveys and studies completed in order to determine how much waste will be generated during the decommissioning project. However, shipment of large volumes of radioactive material will not occur until the second phase of the project, scheduled to begin in 2029.

Low level radioactive waste shipped from TMI to the EnergySolutions disposal site in Utah will be carefully surveyed to ensure they meet strict NRC and Department of Transportation (DOT) packaging, shipping and radioactive requirements. The low-level waste will be containers with additional shielding as necessary.

That is certainly an option. Many of the structures and components at TMI-2 are not radioactive, the cooling towers being one example. We will work with state and local officials to determine a safe and economical way to dispose of this material in accordance with all federal, state and local regulations.

Because 99 percent of fuel was removed from TMI-2 analysis shows that there are no events which could result in a release that would jeopardize public health and safety. TMI-2 falls below any limits established by the federal government for Protective Action Guidelines used by operating nuclear power plants. Therefore, there is no need for an offsite emergency planning program.

Releasing the site for unrestricted use means the site radiological contamination will have been removed to the point the NRC no longer requires restrictions to protect the public. Note that a small portion of the site will still be restricted while small amounts of core debris remain in an ISFSI until DOE retrieves it.

The waste storage facility and surrounding fences typically take up approximately 5 acres. This area would remain restricted until the US Department of Energy retrieves material.

The site outside of the ISFSI is zoned for industrial use and will be safe for future industrial or commercial application.

The TMI-2 decommissioning will be completed in two phases. Phase 1 will last about 8 years and will focuses on planning and engineering activities, and remediation of the areas impacted by the 1979 core-damage accident. The overall goal of Phase 1 is to reduce the radiological source term at TMI-2 to levels that are generally consistent with a nuclear plant toward the end of its operational life that has not experienced a core-damage accident. The first 4-5 years under Phase 1 will be preparation for decommissioning, including engineering work, procurement of long-lead time items, and infrastructure upgrades. Specific Phase 1 decommissioning objectives include: -Reducing the reactor building source term. -Reducing the source term and removing the damaged core debris from the reactor vessel. -Reducing the source term of large components by removing damaged core debris. -Packaging, transporting, and storing the damaged core debris. -Removing, packaging and transporting the Class B and C radioactive waste for disposal in Texas. Phase 2 will involve work generally typical of a nuclear plant that did not experience an accident. This phase will last about another 8 years. The overall goal of Phase 2 is to decommission the TMI-2 site to a level that permits the release of the site, except for an area to be set aside for waste storage of the damaged core debris. Specific Phase 2 decommissioning objectives include: -Removing, packaging, and disposing of all remaining systems and equipment in preparation for structural demolition and transporting the Class A radioactive waste in Utah. -Demolishing and dispositioning all plant structures to nominally three feet below grade. -Demolishing the cooling towers. -Performing the surveys to verify the site is clean -Backfilling the site to the existing grade elevation. Phase 2 is expected to complete in 2037.

No not at all. In fact, we have current information on the radiological conditions throughout the plant and key areas are continuously monitored to detect any changing conditions. Because TMI-2 has been dormant for several decades, conditions inside the plant have been stable and predictable for quite some time.

The remaining core debris (less than one percent of the original total) will be recovered from TMI-2 and packaged in canisters and cask systems like those used for storage of spent nuclear fuel at other nuclear plants. Because the U.S. Department of Energy has not licensed a national spent fuel repository the casks will be stored in an Interim Waste Storge Facility along with the spent nuclear fuel casks from TMI-1. We expect that the TMI-2 core debris will be stored in about a dozen casks. All the other radioactive waste generated during the decommissioning will be shipped to a licensed low-level radioactive waste facility in Utah or Texas.

YES, WE HAVE FORMED A COMMUNITY ADVISORY PANEL (CAP) THAT CONSISTS OF A DIVERSE, CROSS-SECTION OF THE COMMUNITY. WE VALUE OUR RELATIONSHIPS WITH THE COMMUNITIES AROUND TMI AND BELIEVE THE CAP WILL PROVIDE US WITH AN OPPORTUNITY FOR EFFECTIVE TWO-WAY FLOW OF INFORMATION. THESE MEETINGS ARE OPEN TO THE PUBLIC AND WE POST AGENDAS AND REPORTS ON OUR WEBSITE. WILL TMI
