US Study Shows Inertial Fusion Implosions Can Tolerate Certain Asymmetries

Researchers at the Lawrence Livermore National Laboratory (LLNL) in the US have recently found that implosion designs for inertial fusion energy (IFE) can withstand considerable imperfections before performance degrades sharply. This result aids in the design of fuel targets for future fusion power plants, particularly in assessing the tolerance of target capsules to errors under high-frequency injection and laser-driven conditions. The study's simulation results show the density (top) and temperature (bottom) at the instant just before fusion reactions peak in an asymmetric implosion. The hottest spot coincides with the point of highest fuel density, indicating direct ignition of high-density fuel jets driven by asymmetry. The image was recently selected for the cover of Physics of Plasmas...

France Authorizes CEA to Dismantle the Pégase Research Reactor Facility at Cadarache

The French Official Journal published a decree on August 23 authorizing the French Alternative Energies and Atomic Energy Commission (CEA) to carry out dismantling operations on the Pégase (Pégase) nuclear facility located at the Cadarache site in Saint-Paul-lès-Durance, Bouches-du-Rhône department. The facility is classified as Basic Nuclear Installation No. 22 (INB 22). The decree specifies the implementation phases for the partial dismantling of the Pégase research reactor and authorizes the CEA to build the equipment required for the dismantling operations. Under the decree, the boundaries of the Pégase facility will be adjusted to provide the necessary space for the layout of dismantling equipment and the temporary storage of waste generated during the dismantling process.

Fukui Prefecture in Japan Likely to Approve KEPCO's Dry Storage Facility for Spent Nuclear Fuel

According to multiple officials of Fukui Prefecture, Japan, Governor Takato Ishida of Fukui Prefecture is expected to approve Kansai Electric Power Company's (KEPCO) construction of a dry storage facility for spent nuclear fuel at its nuclear power plants within the prefecture. If completed, this would mark the first adoption of such an on-site interim storage facility at KEPCO's nuclear power plants. A dry storage facility is used to store spent nuclear fuel discharged from reactors. The basic approach involves placing spent fuel into dedicated metal containers and cooling them naturally through air circulation, without relying on electrical systems. Since the containers themselves can be transported by ship or trailer, subsequent off-site transfer is relatively convenient; even in the event of a power outage, the associated accident risk is considered low. Japan Atomic Power Company (JAPC) and Shikoku Electric Power Company operate nuclear power plants that have already adopted this storage method.

World's First Full-Stack MRI Brain-Computer Interface Solution "uMR Shenguan" Officially Released

On August 23, the first National MRI Brain-Computer Interface Conference, themed "Integration · Decoding · Modulation — Ushering in a New Era of Brain-Computer Interaction," was held in Tianjin. At the conference, United Imaging Healthcare and Tianjin University jointly released the world's first full-stack MRI brain-computer interface solution, "uMR Shenguan." uMR Shenguan spans the entire translational chain of brain-computer interfaces from fundamental research to clinical application, advancing the realization of "understanding the brain, precise modulation, and making neural plasticity measurable and controllable." It is understood that uMR Shenguan is built on United Imaging's uMR series equipment as its hardware foundation, addressing key technical challenges in the closed loop of "reading the brain — writing the brain — verification" in brain-computer interfaces, providing a complete technical system that upgrades MRI equipment from a mere "imaging tool for structure" to a "central platform" participating in the entire brain-computer interaction process.

Magnitude 3.1 Earthquake in South Korea Does Not Affect Safety of Nuclear Facilities

On August 23, the Nuclear Safety and Security Commission (NSSC) of South Korea reported that at 6:43 a.m. that day, a magnitude 3.1 earthquake occurred approximately 21 kilometers northwest of Haenam County, South Jeolla Province, South Korea. It was confirmed that all nuclear reactors and related nuclear facilities in South Korea were operating stably, with no abnormalities detected. The nuclear facility closest to the epicenter was the Hanbit Nuclear Power Plant, approximately 83.2 kilometers away. The peak ground acceleration recorded at this plant during the earthquake was 0.0032g, far below its seismic design basis of 0.2g, and it is expected that the safety of the facility will not be affected. The Hanbit Regional Office of the NSSC has conducted emergency safety inspections at the Hanbit Nuclear Power Plant site...
