Demolition Begins on Contaminated Buildings in Isotope Area at Oak Ridge National Laboratory

The Oak Ridge Environmental Management Office in Tennessee recently initiated demolition of a group of highly contaminated buildings in the Isotope Area at Oak Ridge National Laboratory. Located in the laboratory's central campus, this area is considered one of the more challenging sites in the local cleanup effort. The Isotope Area comprises 10 facilities, constructed between the late 1940s and early 1960s, which once served the laboratory's isotope program. These facilities were used for decades in the production, processing, and research of chemical elements for medical, industrial, and scientific applications. As the laboratory evolved, the facilities were taken out of service in the early 1990s but remained standing. According to reports, the area retains contaminated...

LUX-ZEPLIN Experiment Reports Anomalous Event in Dark Matter Search, More Data Needed for Verification

On September 1, the LUX-ZEPLIN (LZ) dark matter direct detection experiment released a new analysis result: researchers recorded a single-particle interaction event in the data whose characteristics could be interpreted as a Weakly Interacting Massive Particle (WIMP) signal, but the current evidence is insufficient to confirm a dark matter discovery. The LUX-ZEPLIN main detector is shown in a surface laboratory before being installed underground. (Matthew Kapust/Sanford Underground Research Facility) The LZ experiment involves approximately 250 scientists and engineers from 39 institutions, with the detector located nearly one mile underground at the Sanford Underground Research Facility in South Dakota, USA, and managed by the U.S. Department of Energy's Lawrence Berkeley National...

U.S. to Conduct Underwater Neutrino Detection Tests in Lake Superior and Vermilion Lake

From October 2026 to approximately April 2027, a team of researchers from U.S. universities and government agencies will conduct underwater neutrino tests in Lake Superior and Vermilion Lake. The project, named the Experimental Neutrino Detector (END), aims to validate a baseline detection system in natural water bodies to identify the NuMI neutrino beam produced by Fermi National Accelerator Laboratory and distinguish it from cosmic-ray backgrounds and other noise in shallow-water environments. END will place underwater neutrino detectors on the lakebed of Lake Superior where the Fermilab neutrino beamline passes through—near Two Harbors, Minnesota. The beamline will continue toward...

Japan Approves Adjusted Tsunami Height Assessment for Genkai Nuclear Power Plant

At its regular meeting held on September 2, Japan's Nuclear Regulation Authority (NRA) formally approved Kyushu Electric Power Co.'s assessment of the maximum potential tsunami height at the Genkai Nuclear Power Plant site in Saga Prefecture. Under this adjustment, the maximum tsunami height on the northwest side of the Genkai plant site has been raised to 14 meters; previously, the maximum tsunami height on the north side of the site was 6 meters. The NRA determined that the ground surface on the northwest side of the Genkai plant site is covered by bedrock with an elevation of 16 meters, and therefore no additional disaster prevention measures are required even under the new tsunami height assessment. In July, the NRA had already approved the review report draft submitted by Kyushu Electric Power...

World's First 250,000 Tonne-Meter Ring Crane Rolls Off Production Line, Supporting Hualong One 2.0 Nuclear Power Construction

On August 31, the world's first 250,000 tonne-meter ring crane, jointly developed by SANY Heavy Lift and China Energy Engineering Group Guangdong Thermal Power & Litte Company, rolled off the production line at SANY's Huzhou Industrial Park in Zhejiang. Designed for the "one crane, two islands" construction requirements of Hualong One 2.0, the equipment can address the engineering challenge of covering module hoisting for two nuclear islands with a single unit, marking a key domestic localization breakthrough in China's ultra-large-tonnage nuclear power hoisting equipment. With the advancement of the Hualong One 2.0 "one crane, two islands" construction method, nuclear power projects have imposed higher requirements on the working radius, load capacity, and hoisting precision of heavy lifting equipment. In the past, related high-end equipment technology was long controlled by a few overseas companies. The 250,000 tonne-meter ring crane rolled off the production line this time has undergone seven years of technical research, achieving breakthroughs in structural design, manufacturing processes, and assembly control.

Russian Academy of Sciences Reveals Mechanism of Microbial Bioremediation Reducing Actinide Content in Groundwater

September 1, 2026 news: Researchers from the Vernadsky Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Sciences, in collaboration with the Frumkin Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences and other institutions, studied the biogeochemical mechanisms affecting the distribution of actinides such as uranium, plutonium, and neptunium during bioremediation of nitrate-contaminated groundwater. Radionuclide-contaminated groundwater is a significant environmental issue in areas associated with nuclear fuel cycle facilities. Long-lived actinides such as uranium, plutonium, and neptunium, once released into the environment, can migrate over considerable distances with groundwater. Bioremediation, which alters geochemical conditions by stimulating natural microbial processes in the subsurface environment, is considered a potential approach for remediating contaminated zones...
