Russian Team Proposes Compact "Siberian Snake" Design for NICA Collider to Control Proton Polarization

Russian Team Proposes Compact "Siberian Snake" Design for NICA Collider to Control Proton Polarization

Experts from the Moscow Institute of Physics and Technology and the Joint Institute for Nuclear Research have proposed a compact Siberian snake magnetic field device design for Russia's NICA collider. The device employs a transverse magnetic field, aiming to maintain proton spin direction during acceleration to a maximum of 13.5 GeV and control polarization orientation during experiments. Related numerical simulations of proton polarization show that this design can effectively suppress beam depolarization. Russia's NICA accelerator complex — Moscow Institute of Physics and Technology press office In an accelerator, proton beams travel along a closed orbit, and particle spins precess around a specific rotation axis. When the beam reaches certain energies, spin may resonate with periodic perturbations in the ring structure, causing beam depolarization; without dedicated control measures, the beam polarization state required for experiments would be difficult to maintain.

South Korea's Nuclear Expansion Faces Fuel Supply Pressure as Enriched Uranium Costs Surge Nearly Sixfold in Seven Years

South Korea's Nuclear Expansion Faces Fuel Supply Pressure as Enriched Uranium Costs Surge Nearly Sixfold in Seven Years

Against the backdrop of accelerating global nuclear power construction and surging electricity demand from AI data centers, the nuclear fuel supply chain is facing new tensions. Due to limited uranium enrichment capacity and sanctions affecting Russian-related supplies, international uranium enrichment prices have risen sharply over the past seven years. South Korea's nuclear expansion plans are consequently facing fuel procurement pressure, with industry experts concerned that if mid- to long-term nuclear fuel security proves insufficient, newly built nuclear units could face operational risks in the future. Korea Hydro & Nuclear Power (KHNP) recently disclosed that South Korea's domestic annual enriched uranium consumption is expected to increase from approximately 460 tons currently to about 540 tons next year. The rising demand mainly stems from the overlap between life-extension operations of some older nuclear units and the commissioning of new units...

US FRIB Research Reveals Low-Energy Gamma-Ray Enhancement Originates from Nuclear Magnetic Transitions

US FRIB Research Reveals Low-Energy Gamma-Ray Enhancement Originates from Nuclear Magnetic Transitions

An international research team led by the US Facility for Rare Isotope Beams (FRIB), with participation from Lawrence Livermore National Laboratory (LLNL) and other institutions, recently published findings in Nature that explain a long-standing question in nuclear physics: why some atomic nuclei emit anomalously high numbers of low-energy gamma rays. Image: FRIB Gamma rays are a type of electromagnetic radiation. Excited atomic nuclei release gamma rays during radioactive decay, gradually returning to lower, more stable energy levels. Over the past few decades, scientists have discovered that certain nuclei exhibit a low-energy enhancement phenomenon, where the number of low-energy gamma rays emitted exceeds expectations. However, this phenomenon is not universal, and its occurrence is theoretically difficult to predict.

Japan's Nuclear Power Revival Enters Supply Chain Rebuilding Phase, with Spent Fuel and Engineering Capacity as Key Constraints

Japan's Nuclear Power Revival Enters Supply Chain Rebuilding Phase, with Spent Fuel and Engineering Capacity as Key Constraints

As Japan advances energy security, reduces dependence on fossil fuel imports, and expands low-carbon electricity supply, the focus of the country's nuclear power market is shifting from mere reactor restarts to a comprehensive supply chain rebuild covering manufacturing, operations and maintenance, life extension, fuel cycle, and waste management. GlobalData estimates Japan's nuclear power generation at 101.0 TWh in 2025 and projects it to increase to 123.3 TWh by 2035. Japan's policy target is to maintain nuclear power at approximately 20% to 22% of the electricity generation mix. Based on total annual electricity demand of approximately 1,050 TWh, a 20% nuclear share corresponds to about 210 TWh, while a 22% share corresponds to about 231 TWh. Compared with the 2025 nuclear generation figure of 101.0 TWh, the estimated gap is approximately 109 TWh to 130 TWh.

Removal of Highly Radioactive Spent Fuel Begins at Unit 2 of Fukushima Daiichi Nuclear Power Station

Removal of Highly Radioactive Spent Fuel Begins at Unit 2 of Fukushima Daiichi Nuclear Power Station

Tokyo Electric Power Company Holdings (TEPCO) said on August 17 that it has begun removing spent fuel assemblies with high radiation levels from the spent fuel pool of Unit 2 at the Fukushima Daiichi Nuclear Power Station in northeastern Japan, the site of a severe nuclear accident. Last month, TEPCO removed 28 unused nuclear fuel assemblies from the Unit 2 spent fuel pool. Compared with spent fuel, these unused fuel assemblies pose relatively lower risks. The company plans to complete the removal of spent fuel from Unit 2 by the end of fiscal year 2028. To date, the Unit 2 spent fuel pool contains a total of 587 spent fuel assemblies, of which TEPCO has completed the removal of...

Radioactive liquid waste leak suspected at QST's underground facility in Chiba due to record rainfall

Radioactive liquid waste leak suspected at QST's underground facility in Chiba due to record rainfall

According to Japanese media reports, due to record-breaking rainfall in Chiba Prefecture, an underground facility of the National Institutes for Quantum Science and Technology (QST) in Chiba City was flooded, and radioactive liquid waste in underground storage tanks at the facility may have mixed with rainwater and leaked outdoors. QST stated that as of the 13th, an estimated 2,000 to 3,000 liters of liquid waste had accumulated in the relevant underground storage tanks. After investigating water bodies around the tanks, the institute confirmed that detected radioactive material concentrations were below standard values, and no environmental impact has been indicated so far. QST reported the incident to national and local governments the following day and plans to submit preventive measures to the Nuclear Regulation Authority of Japan.

Safety measure costs after Japan's nuclear plant accident rise to at least 6.606 trillion yen

Safety measure costs after Japan's nuclear plant accident rise to at least 6.606 trillion yen

A survey of 11 Japanese electric power companies shows that the total cost of safety measures required for nuclear plants to meet new regulatory standards following the Fukushima Daiichi accident has reached at least 6.606 trillion yen. Affected by rising prices, this figure has increased slightly from the previous year. About half of the surveyed companies said that rising costs of materials, equipment, and construction have pushed up related expenses, and the total may continue to rise in the future. After the Fukushima Daiichi accident, Japan implemented new nuclear regulatory standards requiring plants to strengthen earthquake and tsunami protection and improve severe accident response measures. Related costs mainly include seawalls, emergency power supplies, filtered venting equipment, and...
