Exploring the Frontier of Advanced Fusion Physics: Physical Mechanisms and Engineering Challenges of D–³He Secondary Neutron Suppression under the Synergy of Hot Tails and Spin Polarization

In the process of controlled nuclear fusion advancing from theoretical exploration to commercial validation, the choice of fuel pathway has always been the core variable determining the engineering feasibility and economics of a reactor. For a long time, the deuterium–helium-3 (D–³He) reaction has been regarded as an ideal "low-neutron" ultimate fusion scheme because its primary products are only charged particles (helium-4 and high-energy protons), it does not directly produce neutrons, and it possesses the potential for direct energy conversion. However, under the traditional thermal equilibrium plasma framework, D–³He is not a truly neutron-free fuel. In October 2026, the U.S. Princeton Plasma Physics Laboratory (PP...

CB20 structural module of Lianjiang Nuclear Power Unit 1 successfully hoisted into place

On October 23, the CB20 structural module of Lianjiang Nuclear Power Unit 1 was successfully hoisted into place, creating favorable conditions for subsequent mainline construction. This marks the completion of all heavy-lift tasks for the unit's main construction, and the project has fully entered the installation and commissioning phase. The CB20 structural module is a core component of the CAP1000 nuclear power passive containment cooling system. It consists of inner and outer cylindrical wall panels, a top plate, and a conical bottom plate, and is located atop the nuclear island shield building. The module is massive in scale and features a thin-walled annular structure, making it prone to deformation from uneven forces during hoisting, with high precision requirements for positioning and alignment. To ensure the successful completion of this milestone, the Lianjiang Project Department adhered to Party building leadership and established a Party member vanguard team for equipment and module installation. With a work attitude of "safety first, quality foremost," they coordinated and planned construction tasks, meticulously organized hoisting work, and through special progress meetings focused on key difficulties such as module deformation control and hazard elimination. They adopted multiple advanced technologies including 3D scanning interference analysis, BIM modeling to avoid conflicts, and wireless force measurement systems for real-time leveling of hoisting slings, ensuring the entire hoisting process was safe, orderly, and controllable.
