Under the leadership of Secretary Chris Wright, the Department of Energy has three pillars. First, is to ensure nuclear deterrence for prosperity at home and peace abroad. Second, is to be the global leader for science and innovation. Third, is to drive President Trump's golden era of American energy dominance to keep consumer prices low and enable American industry to thrive. 

Americans want affordable, reliable and secure electricity. A year in, the Trump Administration is delivering. Innovative partnerships are bringing together the brightest American minds to win the global AI race. The energy demand for AI is driving restoration of existing power plants and driving construction of new power generation and grid infrastructure improvements. Increased energy demand is also driving the nuclear energy renaissance. American energy is being added by cutting burdensome red tape, restoring common sense, reducing delays for energy infrastructure and ending Biden-era limits on consumer choices. The future of American energy, innovation and manufacturing is bright once again.

Throughout 2025, EM has been there every step of the way addressing the legacy of the past and playing a critical role in the Department's three-pillared vision for American security, science and energy.

  • Leveraging our assets to accelerate infrastructure and energy generation to support President Trump's Genesis Mission, lower energy costs, increase grid reliability and power AI data centers.
  • Decommission and demolition of buildings to create space for labs, AI infrastructure, national security priorities and nuclear energy.
  • Leveraging President Trump's Executive Orders to enhance beneficial reuse and recycle options for metals and materials.
  • Changing the course of the future for our local partner communities by re-developing sites to become hubs for nuclear energy, advanced manufacturing and data centers that create generational jobs and build long-term economic vitality at sites that served our great nation for decades.
  • Renewing the mission to accelerate cleanup, reduce costs and turn our liabilities into assets for the American people.
  • Harnessing land, facilities, capabilities and our expert workforce as we rebuild a domestic supply chain and lead the world towards a future fueled by American nuclear energy.

Over the course of 2025, our team has laid a strong foundation for what will be a new chapter of remediation, revitalization and redevelopment. Whether it's leveraging our skilled workforce, driving innovation, delivering on cleanup or revitalizing land to add advanced nuclear energy to fuel the AI race - there is so much potential to build generational American jobs and make energy more affordable.

We are heading into what will be a breakout year as we act with a renewed sense of urgency and purpose to implement a plan I'm calling EM Vision 2040. We're going to have some big wins in the near future and tremendous progress in the coming year as we evolve into a future-focused organization and enable a transition from nuclear remediation to nuclear renaissance.

Delivering Remediation and Renewal for American Communities 

EM prioritizes a new chapter remediation, renewal and revitalization at sites across the country - empowering communities and partnering with the best of industry to meet commitments and build long-term economic vitality.

Winning American Energy Dominance

EM transforms liabilities into opportunities to support President Trump’s vision for vision for American energy dominance -- enabling a transition from nuclear remediation to nuclear renaissance.

  • In Kentucky, EM is leasing land no longer needed at the Paducah Site to General Matter for a new private-sector domestic uranium enrichment facility, transforming liabilities into opportunities for unleashing American commercial nuclear.
  • In Kentucky, EM is inviting industry to partner on technologies to clean contaminated nickel stored at Paducah and put it to work for the American people. Instead of letting this material sit idle, EM is asking for proposals to transform it into a form suitable for a variety of energy, nuclear power and AI applications. This aligns with Secretary Wright's efforts to roll back roadblocks to recycling metals at DOE sites and supports his mission of putting DOE assets to work - leading the globe in science and innovation and winning the AI race.
  • In Tennessee, EM is continuing the transition from nuclear remediation to nuclear renaissance. In total, land remediated and transferred at Oak Ridge has attracted more than two dozen businesses that have announced $8 billion in capital investments and a projected 2,500 new private sector jobs.
     
    • X-energy started construction this year on a fuel fabrication facility that will be the first of its kind in the United States.
    • EM and Kairos Power are working together to commercialize advanced reactor technology that will grow energy and unleash American nuclear. EM's Oak Ridge team is advising on deep digs as Kairos constructs the foundation for their Hermes Low-Power Demonstration Reactor on cleaned up former EM land.
    • EM transferred over 2,000 acres at Oak Ridge for a $5 billion private investment by Orano for an uranium enrichment facility -- the largest private investment in Tennessee history.
    • Oklo, Inc. is investing $1.7 billion to build the nation’s first privately funded commercial nuclear fuel recycling facility on 250 acres of land EM cleaned up at Oak Ridge.

Strengthening National Security

EM provides services to enable modernization of America’s nuclear deterrent and opens opportunities for national security priorities.

  • In Idaho, EM completed demolition of the second naval reactor prototype plant for DOE's Naval Nuclear Propulsion Program. Tear down of the plant, that supported development of the world's first nuclear-powered submarine, was completed ahead of schedule and under budget. This partnership allows the Office of Naval Reactors to allocate more of their resources towards core missions that are in service of the safety and security of our nation while providing a considerable cost savings for American taxpayers.
  • In New York, EM tore down remaining buildings at the Q-Complex at the Knolls Atomic Power Laboratory and returned the restored site to the Office of Naval Reactors for redevelopment. By providing this service to Naval Reactors, EM has transformed this legacy facility into an opportunity to support critical national security missions.
  • In Tennessee, EM advanced work to help modernize one of the nation’s most important national security sites, hitting the halfway point in its largest Manhattan Project Era demolition project at NNSA’s Y-12 National Security Complex in Oak Ridge and positioning the project for completion.
  • In New Mexico, EM completed a massive modern ventilation system at the nation’s only geologic repository for transuranic waste, the Waste Isolation Pilot Plant (WIPP). Construction was completed safely and efficiently - one year ahead of schedule with cost savings totaling $10 million. This major upgrade helps ensure WIPP’s 
    long-term role in supporting cleanup as well as DOE national security and scientific missions.
