On October 8, Tianwan Nuclear Power Unit 7, invested in and controlled by China National Nuclear Power under CNNC, was successfully connected to the grid for the first time, officially delivering its first kilowatt-hour of electricity to the grid and laying a solid foundation for the subsequent commercial operation of the unit. The first grid connection and power generation of Tianwan Nuclear Power Unit 7 is a vivid practice of CNNC joining hands with all parties to deeply study the spirit of General Secretary Xi Jinping's important speech at the groundbreaking ceremony of China-Russia nuclear energy cooperation projects, thoroughly implement the "four revolutions, one cooperation" new energy security strategy, and respond to national strategic deployments with concrete actions. On May 19, 2021, President Xi Jinping, via video link in Beijing, together with Russian President Putin, witnessed the groundbreaking ceremony of the two countries' nuclear energy cooperation projects — Tianwan Nuclear Power Plant Units 7 and 8 and Xudabao Nuclear Power Plant Units 3 and 4. General Secretary Xi Jinping put forward the earnest instructions of "adhering to safety first and setting a model for global nuclear energy cooperation," "adhering to innovation-driven development and deepening the connotation of nuclear energy science and technology cooperation," and "adhering to strategic collaboration and promoting the coordinated development of the global energy governance system." Over the past five years and more, under the guidance of higher-level ministries and commissions as well as local governments at all levels, all construction participants of Tianwan Nuclear Power Units 7 and 8 have fully implemented General Secretary Xi Jinping's earnest instructions at the project construction site, and in accordance with the requirements of the Party Group of the Group Company, advanced project construction, commissioning, and other work with high quality and high standards, building Tianwan Nuclear Power Units 7 and 8 into a demonstration project of China-Russia nuclear energy cooperation, a benchmark project for global nuclear power construction, and a livelihood project benefiting the local area. In particular, to ensure the smooth grid connection of Unit 7, Jiangsu Nuclear Power joined hands with all parties to uphold a rigorous and meticulous working attitude and collaboratively completed key operations such as reactor protection logic verification, reactor criticality, steam turbine rolling, and generator short-circuit tests. Subsequently, the unit will carry out a series of tests as planned to further verify unit performance and ensure that commercial operation conditions are met. It is understood that the Tianwan Nuclear Power Base plans to build 8 units. Units 1-6 have already generated more than 550 billion kilowatt-hours of electricity safely and stably, and Unit 7 is expected to enter commercial operation within the year. After all 8 units of the Tianwan Nuclear Power Base are put into operation, the total installed capacity will exceed 9 million kilowatts, with annual power generation exceeding 70 billion kilowatt-hours, and annual carbon dioxide emissions reduced by 57.4 million tons, injecting strong nuclear power into optimizing the energy structure of East China, ensuring regional energy security, helping achieve the national "dual carbon" goals, and promoting green, low-carbon, and high-quality development.

International Researchers Successfully Develop the First Autonomous Thorium-229 "Nuclear Clock": Featuring Ultra-Strong Interference Resistance and a Fully Autonomous Closed-Loop Stable Operation Mechanism

Recently, the press office of TU Wien (Vienna University of Technology) announced that a team of scientists from Austria, Germany, and the Czech Republic has successfully developed the world's first nuclear clock based on the thorium-229 (chemical symbol ²²⁹Th) atomic nucleus. This nuclear clock possesses extremely high interference resistance and is capable of operating in a fully autonomous mode without external stabilization. The research team stated that, compared with traditional atomic clocks that operate using entire atoms, timekeeping using atomic nuclei can theoretically achieve higher measurement precision. Two years ago, they successfully controlled the transition process of the thorium-229 atomic nucleus for the first time, but to achieve extremely high-precision timekeeping, it was still necessary to solve the nuclear clock...

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...
