US Hanford Submits Permit Modification Applications to Accelerate Tank Waste Cleanup via "Vitrification + Grouting"

The U.S. Department of Energy's Hanford Field Office recently submitted two permit modification applications to the Washington State Department of Ecology, planning to accelerate the cleanup of radioactive waste in tanks at the Hanford site through a dual-track treatment strategy of "vitrification + grouting." The DOE stated that this approach is expected to reduce risks from aging tanks and save taxpayers billions of dollars. The waste primarily targeted by these applications is low-activity liquid waste processed through the Tank-Side Cesium Removal system, which removes more than 99.9% of radioactive materials from the treated waste. The DOE stated that the proposed permit changes would integrate tank-side treatment, grout solidification, and out-of-state disposal into a standardized process to continue advancing the treatment and transfer of some waste beyond the capacity of the Waste Treatment and Immobilization Plant.

TMTG Advances $6 Billion-Plus Merger with TAE, Pivoting to Commercial Fusion Energy

Trump Media & Technology Group (TMTG) recently disclosed that it will proceed with its merger plan with fusion energy firm TAE Technologies (TAE), despite reporting significant losses in the second quarter. The deal is valued at over $6 billion, with TMTG committing to invest $300 million in TAE before the transaction closes. According to company disclosures, TMTG recorded a loss of $238 million in the second quarter of 2026, with revenue of $1.7 million and total assets approaching $2 billion. In the first half of 2026, the company's net loss widened to $644 million, compared to a loss of $52 million in the same period last year. The company attributed the widening losses primarily to...

U.S. Team Proposes New In-Situ Cleaning Method for Porous Tungsten Walls in Fusion Devices

Researchers from the U.S. Department of Energy's Princeton Plasma Physics Laboratory, Princeton University, and Pennsylvania State University have proposed an in-situ cleaning method for fusion system wall materials, which uses heating combined with neon plasma to remove contaminants from the surface of porous tungsten materials after components are installed and sealed within a vacuum chamber. The research findings have been published in *Nuclear Materials and Energy*. Image credit: Kyle Palmer / PPPL Communications Department. Fusion system walls must withstand extreme temperatures. Liquid lithium is considered a promising wall protection material, which can be retained within porous tungsten wall tile structures much like water absorbed by a sponge. However, this...

GAO Report Urges DOE-EM to Learn from Canada, UK, France, and Belgium in Reshaping Nuclear Waste Cleanup Strategy

The U.S. Government Accountability Office (GAO) noted in a new report that countries such as Canada, France, and the United Kingdom have taken proactive measures in recent years to accelerate nuclear waste cleanup. The report recommends that the U.S. Department of Energy's Office of Environmental Management (DOE-EM) engage in strategic exchanges with these countries to identify and evaluate alternative approaches that could reduce risks, lower costs, or expedite cleanup activities. Currently, DOE-EM estimates its cleanup mission could cost between $641 billion and $840 billion and may not be completed until 2100. The report found that while DOE-EM has some level of exchange with other countries on nuclear cleanup, such exchanges are not strategic and lack proactive learning...

U.S. Department of Energy Highlights Progress in Legacy Waste Cleanup and Medical Isotope R&D

Recently, senior officials from the U.S. Department of Energy attended an event hosted by the U.S. House Nuclear Cleanup Caucus, presenting the application progress of legacy nuclear waste cleanup efforts in medical isotope R&D and future energy technologies. The event, themed "DOE's Isotope Mission: Legacy Cleanup Saves Lives, Empowers America's Future," focused on how nuclear cleanup missions align with isotope production and medical research. DOE's Under Secretary for Science Dario Gil, along with Oak Ridge National Laboratory Environmental Management Office Manager Eric Olds and Savannah River Operations Office Manager Edwin DeShon, jointly attended the event. DeShon...

Illinois Restarts Nuclear Power in Bid to Address Energy Challenges

Illinois is actively exploring nuclear energy to address potential electricity shortages. Governor Pritzker signed an executive order requiring agencies to study adding at least 2 gigawatts of energy supply, enough to power 2 million homes or 20 large data centers. Earlier, in January of this year, the state passed the Clean and Reliable Grid Affordable Act, lifting a nearly four-decade ban on building new large-scale nuclear plants. This move aims to ensure stability of power supply and affordability of prices, especially amid growing energy demand. Illinois's nuclear development is not without challenges. For a long time, the United States has lacked a solution for safely storing nuclear waste...
