ENN's "Xuanlong-50U" Device Successfully Achieves Hydrogen-Boron Fusion Reaction

ENN's "Xuanlong-50U" Device Successfully Achieves Hydrogen-Boron Fusion Reaction

In late September 2026, ENN achieved a major breakthrough in the commercialization of hydrogen-boron fusion: the Xuanlong-50U device achieved a hydrogen-boron fusion reaction. This is the first time a global commercial fusion company has achieved a hydrogen-boron fusion reaction on its own device, and also the first time China's magnetic confinement fusion device has achieved a clean neutron-free fusion reaction with advanced fuels (hydrogen-boron, deuterium-helium-3). Hydrogen-boron fusion has commercialization advantages such as being neutron-free, having abundant and easily accessible fuel, and low cost. Its product is helium (α particles), but compared with deuterium-tritium fusion, it requires higher reaction temperature and triple product, and more demanding reaction conditions. In this experiment, the ENN fusion team, through the synergy of high-energy neutral beam injection and radio-frequency waves, greatly increased the non-thermal equilibrium fast proton fraction at the first resonance peak of the hydrogen-boron reaction...

Zhejiang Jinqimen Nuclear Power Unit 1 Pressurizer Relief Tank Successfully Hoisted into Place

On August 30, the pressurizer relief tank, a major nuclear island equipment item of Unit 1 at Zhejiang Jinqimen Nuclear Power Plant, contracted by China Nuclear Industry Fifth Construction Co., Ltd. (CNF), was successfully hoisted into place. The entire hoisting process was smooth and orderly, with overall safety and quality under control. This hoisting has laid a solid foundation for the subsequent installation of main nuclear island equipment and the construction of the primary loop system. The pressurizer relief tank is an important auxiliary equipment of the reactor coolant system in a nuclear power plant. Its main function is to collect and condense the high-temperature and high-pressure steam discharged from the pressurizer safety valves, ensuring the safe and stable operation of the reactor system. The relief tank hoisted this time is pre-installed equipment in the nuclear island. The main body of the equipment is heavy in weight and large in size, with limited hoisting workspace. After being hoisted into place, it needs to be placed in the nuclear island building for a long period, and subsequent construction will be constrained by space, making it necessary to introduce the equipment precisely within the civil construction window period.
