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...

US Inertia Fusion Fuel Preparation Time Significantly Reduced

US fusion startup Inertia Enterprises said it has made progress in inertial fusion energy fuel preparation in collaboration with Lawrence Livermore National Laboratory (LLNL), reducing the time required for the critical step of forming a cryogenic deuterium-tritium fuel layer from potentially several days in the past to tens of minutes. The company said this achievement completes a key task in the first phase of its commercial fusion power plant development goals. The fundamental approach of inertial fusion energy involves using high-energy lasers to compress and heat small targets containing deuterium-tritium fuel, bringing the fuel to ignition conditions and releasing energy. The National Ignition Facility (NIF) has already...

Shenju Nuclear Energy Unveils "Jinwu-1" Spherical Torus Fusion-Fission Hybrid Reactor Design

Shenju (Sichuan) Nuclear Energy Co., Ltd. has unveiled the first-generation device, the Jinwu-1 design, which adopts the spherical torus fusion-fission hybrid reactor technology pathway, driving a subcritical nuclear energy system with a compact fusion neutron source to achieve functions such as energy amplification, fuel breeding, and transmutation of long-lived nuclides. According to the design, Jinwu-1 uses a 50 MW-class fusion power as the conceptual design baseline, employing high-temperature superconducting magnets, a replaceable center column, and a modular subcritical nuclear energy zone. Its fusion core has a major radius of approximately 1.5 meters, with the goal of delivering approximately 40 MW of fusion neutron power at 14.1 MeV energy, serving as an industrial-grade neutron source. In terms of system design, Jinwu-1 amplifies fusion neutron energy through a subcritical fission blanket...
