ANS Executive Director/CEO Craig Piercy’s reflection on the 80th anniversary of the Trinity Test (Nuclear Newswire, July 16) was a thoughtful and fitting remembrance of the achievements and legacy of the World War II generation of nuclear pioneers. We also see legacy environmental cleanup as a vital next step as our industry launches what Secretary of Energy Chris Wright has defined as “Manhattan Project 2.0.”

Small modular reactor developer X-energy, together with its fuel-developing subsidiary TRISO-X, has selected Clark Construction Group to finish the building construction phase of its advanced nuclear fuel fabrication facility, known as TX-1, in Oak Ridge, Tenn. It will be the first of two Oak Ridge facilities built to manufacture the company’s TRISO fuel for use in its Xe-100 SMR. The initial deployment of the Xe-100 will be at Dow Chemical Company’s UCC Seadrift Operations manufacturing site on Texas’s Gulf Coast.

A reactor vessel has been installed by Kairos Power for its third Engineering Test Unit (ETU 3.0) at the company’s campus in Oak Ridge, Tenn.

The Nuclear Regulatory Commission has accepted for review the Tennessee Valley Authority’s construction permit application for a BWRX-300 small modular reactor at its Clinch River site in Tennessee. The NRC expects to complete its review by December 2026.

The Department of Energy’s Oak Ridge Office of Environmental Management recently completed the transfer of a 32-acre parcel at the East Tennessee Technology Park (ETTP) for private sector use. The transfer brings the total amount of property transferred from federal ownership for economic reuse to 1,832 acres at the ETTP, which was once home to the Oak Ridge Gaseous Diffusion Plant.

The Tennessee Valley Authority announced yesterday that it has submitted a construction permit application to the Nuclear Regulatory Commission for the construction of a GE Vernova Hitachi Nuclear Energy BWRX-300 small modular reactor at the Clinch River nuclear site in Oak Ridge, Tenn.

The U.S. Nuclear Regulatory Commission this week shared a portion of the construction permit application from the Tennessee Valley Authority to build a small modular reactor at the Clinch River nuclear site in Oak Ridge, Tenn.

In anticipation of TVA’s filing, NRC staff scheduled two public meetings in Oak Ridge for today, to discuss the agency’s process for licensing nuclear power plants.

The Department of Energy’s Office of Environmental Management said that crews with the Oak Ridge Office of Environmental Management (OREM) and its cleanup contractor UCOR are preparing to demolish another deteriorating Manhattan Project–era building at the Y-12 National Security Complex at Oak Ridge, Tenn.

The Department of Energy’s Office of Environmental Management has awarded a five-year contract worth up to $74.8 million to Independent Strategic Management Solutions for professional support services at the Oak Ridge Office of Environmental Management site in Oak Ridge, Tenn.

In a Q&A posted on TVA’s website last week about a “new nuclear heyday,” Bob Deacy shared his vision for the Clinch River nuclear site in Oak Ridge, Tenn.—and some news about next steps for the company’s small modular reactor plans.

The Tennessee Valley Authority’s senior vice president for the Clinch River project, Deacy described his vision for up to four SMRs built on plots smaller than a football field with state-of-the-art digital equipment and a newly trained workforce providing reliable 24/7 power to the grid.

Oak Ridge National Laboratory has successfully removed legacy radioactive waste stored for more than five decades, marking a significant cleanup milestone. The Oak Ridge Office of Environmental Management (OREM) and cleanup contractor UCOR processed and shipped highly radioactive source material, including radium-226 and boron, out of state for permanent disposal.

Nichols

The Oak Ridger has published the latest in a series of articles about General Kenneth D. Nichols, the Manhattan Project, and the 1954 Atomic Energy Act. The series has been produced by Nichols’ grandniece Barbara Rogers Scollin and Oak Ridge (Tenn.) city historian David Ray Smith. Gen. Nichols (1907–2000) was the district engineer for the Manhattan Engineer District during the Manhattan Project.

As Smith and Scollin explain, Nichols “had supervision of the research and development connected with, and the design, construction, and operation of, all plants required to produce plutonium-239 and uranium-235, including the construction of the towns of Oak Ridge, Tennessee, and Richland, Washington. The responsibility of his position was massive as he oversaw a workforce of both military and civilian personnel of approximately 125,000; his Oak Ridge office became the center of the wartime atomic energy’s activities.”

Diablo Canyon will host a commercial installation of the first on-site generative artificial intelligence deployment at a U.S. nuclear plant.

Pacific Gas & Electric is deploying Atomic Canyon’s Neutron Enterprise to assist the utility’s management of datasets associated with operations of Diablo Canyon. The software, which runs on Nvidia’s full-stack AI platform, enables intelligent document processing, computation of semantic embeddings, and generative capabilities. Its infrastructure allows nuclear facilities to process and analyze vast amounts of complex documentation with unprecedented speed and accuracy, according to the company.

Federal and contractor officials, community leaders, and educators gathered in Knoxville, Tenn., on October 29 for a roundtable event focused on ensuring the Oak Ridge Office of Environmental Management (OREM) and its partners have the resources and infrastructure needed to support a robust, talented workforce in the years ahead.

TerraPower Isotopes, a subsidiary of Bellevue, Wash.–based TerraPower, announced it is now producing actinium-225 at commercial scale, making the medical isotope available to the pharmaceutical industry through weekly production runs. As a result, TerraPower Isotopes said its actinium, after further manufacturing, is now used in multiple drug developers’ radiopharmaceuticals in human clinical trials across the globe.

Workers with the Oak Ridge Office of Environmental Management (OREM) and its contractor UCOR have finished installing the first of three large sludge-settling tanks for the Mercury Treatment Facility at the site’s Y-12 National Security Complex. The tanks, each of which will be 38 feet tall and 15 feet wide with a capacity of 36,000 gallons, provide a visible sign of ongoing progress on the facility where much of the construction has so far been below ground.

Kairos Power accomplished another step forward for its Hermes 2 reactor plans as the Nuclear Regulatory Commission this week published its final environmental assessment and finding of no significant impact.

On September 4, Tennessee Gov. Bill Lee announced that Orano had selected Oak Ridge as its preferred site to build a “multibillion-dollar” uranium centrifuge enrichment facility. For Tennessee, the announcement underscores Oak Ridge’s draw for nuclear technology companies. For Orano and the nuclear power community, the announcement is another sign the nation is edging closer to adding front-end nuclear fuel cycle capacity.

Crews are making significant progress on the construction of the K-25 viewing platform at the Oak Ridge Reservation in Tennessee, the Department of Energy’s Office of Environmental Management announced on August 20. When completed next year, the elevated platform will offer a sweeping panoramic view of the massive 44-acre footprint of the K-25 Building, which once produced enriched uranium used in the weaponry that ended World War II.

Waste Management Symposia announced that the theme of next year’s Waste Management Conference (WM2025) will be “Empowering A Sustainable Future—Advanced Technologies, AI, and Workforce Development across the Nuclear Landscape.” To be held in Phoenix, Ariz., March 9–13, the conference will showcase how new technologies and the evolving digital world are transforming the global nuclear landscape, supply chains, infrastructure, and work norms.
