CNNC Xiyi Waste Barrel Storage Well Grinding Robot Completes On-Site Testing

CNNC Xiyi Waste Barrel Storage Well Grinding Robot Completes On-Site Testing

Recently, the waste barrel storage well grinding robot developed by CNNC Xiyi officially completed on-site testing in the grinding project of the process BOP (three wastes) storage wells of Units 3 and 4 at Xudabao, marking a substantial breakthrough in the field of automated construction in confined deep-well spaces within the nuclear industry. Waste barrel storage wells feature great depth, small openings, high verticality requirements, and high dust concentrations. Traditional manual grinding requires multiple workers to take turns entering the confined space, resulting in long construction cycles and high risks. The grinding robot developed by CNNC Xiyi is equipped with an XYZ three-axis movement mechanism and a multi-degree-of-freedom motion system with R rotation and W width adjustment, covering a working width of 12 meters with a maximum grinding depth of 5 meters, applicable to the construction of standard waste barrel storage wells across various reactor types...

First Concrete Pour Launched for Conventional Island of Jinqimen Nuclear Power Unit 2

First Concrete Pour Launched for Conventional Island of Jinqimen Nuclear Power Unit 2

At 22:16 on August 18, Zhejiang Jinqimen Nuclear Power construction reached another key milestone as the first concrete pour (FCD) for the raft foundation slab of the turbine generator building in the conventional island of Unit 2 was officially launched, marking the full commencement of the main construction of the conventional island of Jinqimen Nuclear Power Unit 2 and the project's official entry into the civil construction phase. The raft foundation slab being poured, as the core load-bearing structure of the conventional island, is a variable-cross-section, super-large-volume, waterproof and impermeable special concrete structure, and is the core section with the largest volume, most critical working conditions, and highest precision requirements among the conventional island raft foundation structures. This construction involves long continuous operation hours, stringent temperature control and crack prevention requirements, and significant construction organization challenges. To ensure the safe and high-quality completion of the project, CNNC Zheneng fully demonstrated the "owner" spirit, played the "backbone" role, and shouldered the "main force" responsibility, jointly establishing a dedicated technical task force with construction and supervision units, building on the mature FCD construction experience of Conventional Island Unit 1 to comprehensively optimize the raft construction process for Conventional Island Unit 2, strictly adhering to the highest quality standards and safety regulations for nuclear power construction.

Russian enterprise develops borated polyethylene material for neutron radiation protection

Russian enterprise develops borated polyethylene material for neutron radiation protection

A neutron radiation protection material developed by Russian company NPO Gelar has obtained relevant certification. The material, named Polikeramoplast-PB, is a borated polyethylene that resembles ordinary gray or black plastic sheets in appearance, but its protective performance derives from the combination of hydrogen and boron. According to reports, the hydrogen in the material effectively moderates fast neutrons, reducing the likelihood of subsequent secondary reactions, while the boron helps absorb moderated neutrons. In contrast, traditional heavy metal materials used for gamma-ray shielding are not suitable for standalone neutron protection, as heavy atomic nuclei have limited attenuation effects on neutrons. The material can be used in radiation therapy room protection systems and combined with lead...

US Oak Ridge National Laboratory Advances Radioisotope Nuclear Battery Development

US Oak Ridge National Laboratory Advances Radioisotope Nuclear Battery Development

On August 17, 2026, the US Department of Energy's Oak Ridge National Laboratory stated that its nuclear battery program is advancing the development of radioisotope power systems to meet the demand for stable, long-life power sources in deep space exploration, long-term power supply in remote areas, and national security-related scenarios. NASA's Perseverance Mars rover poses with several of the 10 sample tubes it placed in a sample depot it established in a region of Jezero Crater called "Three Forks." The rover's radioisotope thermoelectric generator is powered by a nuclear battery. Image credit: NASA/JPL-Caltech/MSSS. Nuclear batteries generate electricity from the energy released by the decay of radioisotopes, making them suitable for environments such as the seafloor, remote deserts, and extraterrestrial surfaces where maintenance is difficult and continuous power supply is needed for years or even decades.
