Professor Yan Lixin's Research Group in the Department of Engineering Physics at Tsinghua University Collaborates to Achieve a Beyond-Megawatt Average Power Laser Optical Enhancement Cavity

Recently, the research group of Professor Yan Lixin from the Department of Engineering Physics at Tsinghua University, in collaboration with the team of Professor Fabian Zomer from IJCLab at Université Paris-Saclay, France, published important progress in the field of high-finesse optical enhancement cavities. The research team achieved a four-mirror bow-tie optical cavity with an average laser power exceeding 1 megawatt and its stable operation at the Tsinghua University Accelerator Laboratory, with a maximum intracavity average power of 1.15 MW, while maintaining an excellent Gaussian fundamental mode. This is the first published work internationally on an optical enhancement cavity with an intracavity average laser power reaching the megawatt level, which will lay a solid foundation for important applications such as the development of steady-state microbunching (SSMB) extreme ultraviolet light sources, quantum electrodynamics (QED) vacuum nonlinearity detection, ion beam photoneutralization for magnetic confinement fusion, and the development of future inertial confinement fusion reactors.

CGN's 33 in-operation nuclear power units achieve RMB-denominated pricing and settlement for operational period insurance

On September 10, the "CGN In-Service Nuclear Power Plant Operational Period Insurance Project Co-Insurance Agreement" was signed in Shenzhen. The agreement achieves RMB-denominated pricing and settlement for major types of nuclear power plant operational period insurance, changing the convention of China's nuclear insurance market's over thirty years of primarily relying on foreign currency transactions. Nuclear insurance is an important type of insurance for ensuring the safe and stable operation of nuclear power units. Due to the enormous insured amount of a single policy, it typically requires joint underwriting by hundreds of insurance companies both domestically and internationally, and is regarded by the insurance industry as one of the most special and complex types of insurance. Since China's first nuclear power plant operational insurance policy——the Daya Bay Nuclear Power Plant operational insurance policy——was issued in 1993, China's nuclear power industry has long followed mature foreign models...

Long-term operation upgrades advanced during outage of Czech Dukovany Unit 3

On September 8, 2026, CEZ Group (CEZ) is utilizing the current outage maintenance window of Unit 3 at the Dukovany Nuclear Power Plant to carry out large-scale modernization of the turbine hall and secondary circuit. These systems are responsible for converting the thermal energy generated by the reactor into electricity and delivering it to the transmission grid. CEZ stated that during this outage, technicians will perform hundreds of inspections, repairs, maintenance activities, and modifications on secondary circuit equipment. In addition to routine inspections required by regulations and operating procedures, preventive maintenance, defect resolution, and equipment upgrades will also be carried out on site, creating conditions for the plant's goal of operating for up to 80 years. Roman Havlín, Director of the Dukovany Nuclear Power Plant, stated that while outage maintenance at nuclear power plants typically draws more attention to the reactor and primary circuit, the turbine hall equipment that ensures actual electricity generation is equally critical, and related equipment will also receive intensive maintenance during the outage.

South Korean civic groups oppose construction of spent fuel storage facility at Hanbit Nuclear Power Plant site

On September 4, the Joint Action Organization Against Hanbit Nuclear Power Plant in the Honam region of South Korea held a press conference in front of the high-level radioactive waste forum venue in Gochang County, North Jeolla Province, demanding the cancellation of plans to build a storage facility at the Hanbit Nuclear Power Plant site and proposing fundamental measures to address nuclear waste issues. The organization stated that Korea Hydro & Nuclear Power (KHNP) is pushing forward with the construction of temporary storage facilities at the plant site on the grounds that the spent fuel pools at Hanbit Nuclear Power Plant may reach saturation by 2030. The organization argued that this move fails to adequately respond to the opinions of residents near the plant and amounts to unilaterally shifting the burden of nuclear waste onto the local community. The organization stated that the current plan involves building storage facilities at the existing nuclear power plant site...

Domestically Produced Nuclear-Grade Resins Fully Verified and Ready for Use

On August 28, China General Nuclear Power Group (hereinafter referred to as CGN) announced that five nuclear-grade resin products developed under its leadership have all been put into engineering application, with a cumulative total of 12 batches used at nuclear power plants including Daya Bay, Ningde, Yangjiang, Taishan, and Hongyanhe. Among them, the first product has been operating stably for over three years in the steam generator blowdown system (APG system) of nuclear power plants, with key performance indicators comprehensively outperforming imported counterparts of the same category, and the domestic nuclear-grade resin production line. Nuclear-grade resins are known as the "kidneys" of nuclear power water treatment systems, serving as core materials that ensure stable water chemistry indicators of nuclear power units and prevent equipment corrosion. For a long time, these materials have been highly dependent on imports, posing supply security risks such as long delivery cycles, unstable batch quality, and rising prices year by year.
