Hanford Site Completes Radioactive Waste Removal from 24th Underground Tank
The Hanford team under the U.S. Department of Energy Office of Environmental Management recently continued its tank cleanup mission, removing radioactive waste from the 24th underground single-shell tank. The cleanup targeted the A-106 single-shell tank. In less than seven months, Hanford Tank Waste Treatment and Storage Project workers transferred approximately 79,000 gallons of waste that had been stored for decades into a double-shell tank for continued safe storage. During operations, the contractor first used water to dissolve salt-based waste on the tank surfaces, then reused the transferred liquid waste to mobilize sludge. This method had last been used nearly a decade ago. The Hanford Site produced plutonium for U.S. nuclear weapons programs between 1944 and 1989...

German-Grenoble Joint Experiment: Bacteria Immobilize 96% of Uranium in Mine Water, Offering New Insights for Legacy Uranium Mine Remediation
More than three decades after the closure of the Schlema-Alberoda legacy uranium mine in Saxony, Germany, remediation pressure continues unabated. After the mine workings were flooded, the water still contains approximately 1 milligram of uranium per liter, far exceeding the World Health Organization's provisional guideline value of 0.03 milligrams per liter for drinking water. This means that even though mining has long ceased, contaminated water must still be treated over the long term to prevent radioactive metals from migrating with groundwater into rivers or drinking water sources. A team involving the Helmholtz-Zentrum Dresden-Rossendorf in Germany, the University of Grenoble, and other institutions conducted experiments directly using real water samples from the mine and achieved noteworthy results: after 130...

LLNL Research in the U.S. Reveals New Mechanisms of Laser Polarization Effects in NIF Inertial Confinement Fusion Experiments
Researchers at Lawrence Livermore National Laboratory (LLNL) have recently discovered in studies related to the National Ignition Facility (NIF) that the polarization state of lasers may influence the cross-beam energy transfer (CBET) process in inertial confinement fusion experiments and could help reduce backscatter and the risk of damage to optical components. The related paper, titled "Effects of Laser Polarization on Cross-Beam Energy Transfer in Inertial Confinement Fusion," was recently published as a featured article in the journal Physics of Plasmas. NIF experiments demand extremely high precision in laser control. The facility's 192 laser beams must be focused to a width of a few millimeters and enter the target area through holes approximately 3 millimeters in diameter located at the top or bottom of a gold hohlraum. The hohlraum is about 2 centimeters in diameter. After the lasers enter the plasma, different beams cross each other and undergo energy transfer, a process known as cross-beam energy transfer. When designing NIF inertial confinement fusion experiments, scientists carefully tune the laser wavelengths to use CBET to balance energy distribution and improve implosion symmetry.

DR Congo Government Responds to Research Allegations of "Uranium" in Cobalt Products, Announces Re-Testing and IAEA Consultations
The government of the Democratic Republic of the Congo (DRC) has recently responded to a study suggesting that its cobalt products may contain traces of uranium. The study, published in the journal *Nature Communications* on July 30, 2026, reported the presence of uranium traces in some exported cobalt hydroxide products from the DRC. As cobalt is a critical raw material in the global new energy battery supply chain, this claim quickly drew external attention to mineral product safety, environmental risks, and supply chain credibility. In an official statement released on August 7 by the Ministry of Communication and Media, the DRC government stated that the allegations should be understood within a scientific and geological context. The government emphasized that the natural co-occurrence of uranium in copper-cobalt deposits in Lualaba Province and Haut-Katanga Province is a geological phenomenon known for over a century, and is neither abnormal nor the result of artificial addition or deliberate manipulation. The government also noted that, under relevant International Atomic Energy Agency standards, if uranium exists only in trace amounts in ores or cobalt concentrates and is not specifically processed for uranium extraction, it should generally not be regarded as nuclear material.

CMS completes high-pileup collision test, validating particle reconstruction algorithms for High-Luminosity LHC operation
In 2025, the Large Hadron Collider (LHC) conducted a dedicated test over several days to simulate high-intensity collision conditions closer to those expected during future operation of the High-Luminosity Large Hadron Collider (HL-LHC). The Compact Muon Solenoid (CMS) experiment team used this opportunity to test whether existing particle tracking, identification, and reconstruction software, along with a new class of machine learning methods, can adapt to the more complex collision conditions of the HL-LHC era. During LHC operation, each crossing of proton beams produces multiple proton–proton collisions simultaneously, a phenomenon known as pileup. The current Run 3 features approximately 65 simultaneous interactions, while the HL-LHC is expected to reach 140 to 200. To...

Taiwan's Nuclear Plant No. 3 safety inspection schedule extended to 2029, nuclear restart progress faces uncertainty
The latest report from the Audit Department shows that the actual progress of Taiwan's nuclear restart may be lower than expected by the public. Although the Ministry of Economic Affairs has determined that Nuclear Plant No. 2 and Nuclear Plant No. 3 are feasible for restart, and Taipower's restart plan for Nuclear Plant No. 3 has been submitted to the Nuclear Safety Commission for review, a gap has emerged in the progress of the critical self-conducted safety inspections. Although the five self-conducted safety inspection contracts for Nuclear Plant No. 3 have been awarded, the contract performance period may be extended to July 2029, casting uncertainty over the original goal of completing document review by the end of 2028. Nuclear Plant No. 3 is currently regarded as the plant with the best chance of advancing toward restart, but its restart process still must clear multiple hurdles including safety review, aging assessment, aging management, and related document review...

Small Modular Reactors Expected to Contribute One-Quarter of Global New Nuclear Capacity by 2050
According to data compiled by the World Nuclear Association (WNA), global nuclear power installed capacity is expected to reach 1,446 GWe by 2050. This projection is based on the continued operation of existing reactors and the implementation of announced nuclear power development targets by governments. Currently, global installed nuclear capacity stands at approximately 403 GWe. To achieve the above scale, an additional approximately 1,043 GWe of nuclear capacity will need to be added. Among this, Small Modular Reactors (SMRs) are expected to contribute about 260 GWe, accounting for roughly one-quarter of global new nuclear capacity. Factors driving nuclear power expansion are increasing. The rapid adoption of artificial intelligence applications has driven up electricity demand from data centers, and the accelerating electrification of transportation and industrial sectors has further elevated the importance of stable, low-carbon electricity supply. Meanwhile, energy security and net-zero emission targets are prompting more countries to reassess the role of nuclear energy in their energy mix.

Sea Temperature Approaching Shutdown Threshold, Nuclear Power Belt on South Korea's East Coast Faces Load Reduction Pressure
Climate change is pushing nuclear power plants on South Korea's east coast toward new operational boundaries. South Korean nuclear plants generally rely on seawater as cooling water; after the heat generated by the reactor drives the turbine, seawater is needed to condense the steam back into water. Once the intake water temperature approaches or exceeds the design seawater temperature set by the equipment, heat exchange efficiency declines, affecting the heat dissipation capacity of key safety systems, and the plant must reduce load or even shut down in accordance with safety regulations. The area currently at greatest risk is around Uljin in North Gyeongsang Province. Data from the National Institute of Fisheries Science shows that nearshore surface seawater temperatures along parts of the east coast have approached 30°C, with multiple observation points near Uljin recording approximately 29.6°C to 30.2°C on the afternoon of August 7.

Unit 2 of Romania's Cernavoda Nuclear Power Plant to Operate for at Least 9 More Days
Unit 2 of Romania's Cernavoda Nuclear Power Plant is expected to continue operating for at least 9 more days. Romania's Acting Minister of Defense and Transport, Radu Miruță, stated that after blasting operations and the removal of underwater obstacles in the Danube River, the water level in the Cernavoda area rose by 4 centimeters over the past 24 hours. The previous day, the water level in the area had dropped by 3 centimeters. Recently, due to persistent drought, the Danube River's water level has fallen to historic lows, putting pressure on the plant's water intake and reactor cooling. To increase water supply in the river section near the Cernavoda Nuclear Power Plant, Romania last week implemented unconventional engineering measures, including blasting a rock formation in the Danube and sinking barges loaded with cargo to alter...
