Nuclear NewsNEW Heat-only method makes critical alloys tougher for nuclear fusion reactors and jet enginesHeat method makes alloys tougher for fusion reactors and jet engines Researchers at the University of Birmingham developed a heat treatment method called Precipitation Induced Recrystallisation to refine alloy grain structures without mechanical force. The technique uses controlled thermal stress to generate internal pressure, shrinking grain sizes significantly in tested titanium alloys. This process provides a reliable way to manufacture durable components for extreme environments like fusion reactors and jet engines. The new PIX technique uses heat treatment to make tungsten and titanium al...Core Content

Nuclear NewsNEW Study finds a better way to separate zirconium and hafniumResearchers at Oregon State University developed a water-based method to separate zirconium and hafnium using choline and thiocyanate ligands. The technique eliminates the need for toxic organic solvents and reduces energy requirements compared to current industrial extraction processes. While the laboratory results show high separation factors, commercial adoption will require further scaling studies and facility modifications. Different shapes of the crystals in the precipitates.

Nuclear NewsNEW Modernizing for more megawatts: Columbia’s EPU journeyEnergy Northwest is advancing an extended power uprate project at the Columbia Generating Station. The multi-year effort will add roughly 186 megawatts of total electrical output to the northwestern regional grid by 2031. Engineers used laser scanning during the recent 2025 refueling outage to map plant structures for upcoming equipment installations. The single-reactor boiling water reactor, which entered commercial operation in 1984 and holds an operating license through 2043, is integrating the uprate modifications into scheduled biennial refueling outages.

History & TriviaNEW Fewer Than 10 American Veterans Who Saw Hiroshima and Nagasaki Are Still Alive. Their Stories Are DiFewer than 10 American service members who entered Hiroshima and Nagasaki as occupation troops in 1945 remain alive. These aging veterans are the last direct witnesses to the immediate human and structural devastation caused by the first wartime use of atomic weapons. For decades, government secrecy orders prevented these personnel from discussing their radiation exposure and observations. Preserving their firsthand accounts provides valuable historical documentation regarding the long-term health effects of radiation on military personnel and the realities of nuclear warfare. American occupation troops witnessed Hiroshima and Nagasaki weeks after the atomic bombs. Fewer than 10 are believed to remain alive.
