SNPDRI Achieves Key Breakthrough in Modular Construction Technology for Ultra-Large Cooling Towers

Recently, the post-doctoral workstation of State Nuclear Electric Power Planning Design & Research Institute (SNPDRI) under State Power Investment Corporation (SPIC) completed the special research on key technologies for modular design and construction of cooling tower X-shaped columns, which passed expert review. The research focuses on the modular construction challenges of prefabricated components for ultra-large cooling towers, systematically tackling the issue from three dimensions: scheme design, numerical simulation, and physical testing, achieving a series of technical results in joint design, reliability verification, and test validation. The research innovatively proposed a complete set of design schemes for multiple types of modular joints. Based on the load-bearing characteristics of cooling tower X-shaped columns, three types of modular column base joints were developed: integral post-cast, hybrid post-cast, and mechanical connection types, as well as three types of modular ring beam joints: composite ring beam, ring beam post-cast strip, and modular ring beam types. Parametric numerical analysis models were also established to achieve refined design of joint structures.

Hungary's Paks Nuclear Power Plant Faces Full Shutdown Due to Record Low Danube Water Level

Affected by persistent drought and high temperatures, the water level of the Danube River at the Budapest section dropped to 23 cm (fixed datum reading, a record low), restricting cooling water intake at the Paks Nuclear Power Plant. Starting Wednesday, July 29, Unit 3 was the first to be shut down; the operator, MVM Paks Nuclear Power Plant Ltd, subsequently stated on its official website that all four units would inevitably be disconnected within the next 24 to 72 hours, with power generation coming to a complete halt. MVM explained that the existing water volume of the Danube is still sufficient to cool the reactors, but the intake pumps can no longer draw water because the riverbed is exposed and the pump inlets are too far from the water surface—an equipment failure rather than an absolute shortfall in cooling water volume. To this end, the Hungarian side deployed 4 pumping barges and 2 floating cranes near the plant as an emergency measure, but with water levels expected to continue falling, a preventive full shutdown remains unavoidable.

Russian researchers detect anomalous signs in bottomonium states using Belle II experiment data

The Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences recently announced that Russian researchers have detected anomalous phenomena in the analysis of data from the international Belle II experiment, indicating that the structure of certain excited states of bottomonium may be more complex than predicted by traditional models. Bottomonium is a class of unstable heavy particles composed of a bottom quark and an anti-bottom quark. Yevgeny Kovalenko, a young researcher at the Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences, stated that analysis of Belle II experiment data suggests that certain excited states of bottomonium may contain lighter quark components. In other words, these particles in specific states may not simply be plain bottom quark–anti-bottom quark combinations.

U.S. Idaho National Laboratory (INL) Develops New Vacuum Attachment for Nuclear Fallout Collection

Nuclear nonproliferation researchers at Idaho National Laboratory (INL) have invented a specialized attachment compatible with commercial handheld vacuum cleaners, designed to safely and efficiently collect radioactive fallout generated after a nuclear explosion. The intense heat from a nuclear blast lifts ground debris into the atmosphere, where it melts and cools into radioactive glass beads less than 1 millimeter in diameter that fall back to the ground. In the past, nuclear experts undergoing training could only collect samples using brooms, dustpans, and ordinary household battery-powered vacuum cleaners, making manual containment difficult and posing extremely high radiation exposure risks. The INL team began producing prototypes with a thermoplastic 3D printer in 2017, and after multiple rounds of iteration, has now commissioned a company in American Falls, Idaho, to mass-produce the attachment using industrial-grade 3D printing, significantly improving durability.
