HD Hyundai Heavy Industries to Invest KRW 238.6 Billion in Dedicated Plant for Manufacturing Major SMR Equipment

HD Hyundai Heavy Industries to Invest KRW 238.6 Billion in Dedicated Plant for Manufacturing Major SMR Equipment

HD Hyundai Heavy Industries announced on September 10 that it will invest KRW 238.6 billion to build a dedicated plant for manufacturing major equipment for small modular reactors (SMRs). The plant will be built on the site of HD Hyundai Heavy Industries' Ulsan Shipyard, with the goal of commencing operations in 2029. SMRs are regarded as one of the next-generation nuclear power technologies. Compared with conventional nuclear power units, SMRs have lower output power, and their major equipment can be configured in a modular manner, combining features such as stable power supply and reduced carbon emissions. As AI data centers requiring round-the-clock, large-scale power supply increase rapidly, SMRs are attracting more attention. According to projections by the Organisation for Economic Co-operation and Development (OECD), by 2050, the global SMR market is expected to grow to 150G...

US Study Says Third Course of Radiation Therapy May Improve Survival and Symptoms in Children with Recurrent DIPG

US Study Says Third Course of Radiation Therapy May Improve Survival and Symptoms in Children with Recurrent DIPG

According to news from the Icahn School of Medicine at Mount Sinai in the United States on September 2, researchers at the institution released a new study on re-irradiation for recurrent diffuse intrinsic pontine glioma (DIPG). The study shows that carefully selected pediatric patients who receive a third course of radiation therapy after disease recurrence may achieve symptom relief, improved quality of life, and potentially prolonged survival. The related study has been published in Practical Radiation Oncology. DIPG is a highly aggressive pediatric brain tumor that occurs in the brainstem region. The brainstem controls critical life functions such as breathing and movement, so the tumor usually cannot be removed surgically. Data show that DIPG mainly affects children aged 5 to 10, and even...

U.S. Research Team Discovers Strong Ultrafast Optical Response Induced by Ionizing Radiation, Potentially Advancing Medical Imaging and Sensing Technologies

U.S. Research Team Discovers Strong Ultrafast Optical Response Induced by Ionizing Radiation, Potentially Advancing Medical Imaging and Sensing Technologies

September 3 news, Stanford University and the U.S. Department of Energy's SLAC National Accelerator Laboratory research team used ultrafast electron and laser pulses to observe a strong ultrafast optical response triggered by ionization processes in semiconductor materials. The related research has been published in Nature Photonics. The researchers believe this discovery could provide new insights for radiography and sensing technologies, and also offer experimental evidence for understanding the fundamental behavior of materials under high-energy particle interactions. Radiation detection is a key technology in particle accelerators, scientific instruments, medical imaging, and security screening equipment.

ORNL Neutron Imaging Technology Reveals Healed Rib Fracture in Tyrannosaurus Rex Fossil

ORNL Neutron Imaging Technology Reveals Healed Rib Fracture in Tyrannosaurus Rex Fossil

Neutron imaging technology at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) has helped researchers from the University of Regina in Canada and other institutions observe rare healing signs inside the fossilized bones of a Tyrannosaurus rex, providing new insights into ancient life from approximately 66 million years ago. The subject of this study is a fractured rib from "Scotty," the largest Tyrannosaurus rex skeleton ever discovered. Researchers found that this rib preserved a wound-healing process rarely seen in the fossil record: after the fracture occurred, iron-rich blood entered the injured area and formed a network of blood vessels to promote healing; however, before the rib had fully healed, Scotty died and was preserved in a salt marsh environment, which slowed the decomposition of the remains...

Study Says Neutrino Laser Physically Impossible Due to Mechanism Constraints

Study Says Neutrino Laser Physically Impossible Due to Mechanism Constraints

On September 2, physicists at the Massachusetts Institute of Technology published two papers in Physical Review Letters analyzing a previously proposed neutrino laser concept. The research concludes that, due to atomic recoil effects and the fermionic nature of neutrinos, the scheme of using radioactive atomic clouds to produce laser-like neutrino beams is physically impractical. Neutrinos are elementary particles with extremely small mass and very weak interactions with ordinary matter. Earlier research had envisioned cooling radioactive atomic clouds to nanokelvin temperatures to form a Bose-Einstein condensate. According to this concept, atoms in a quantum coherent state might decay synchronously, producing neutrino beams with strong directionality through a quantum amplification effect similar to superradiance...
