Danube water levels continue to decline, Unit 4 of Hungary's Paks Nuclear Power Plant reduces power output
Affected by persistent drought, water levels of the Danube in Hungary have dropped to low levels, impacting the operation of the Paks Nuclear Power Plant, which relies on Danube water for cooling. The plant's operator announced on July 31 that, due to a further drop in the water level at the Paks section to -126 cm, experts would reduce the power output of Unit 4 by 50% starting from 22:45 local time on July 31. The Paks Nuclear Power Plant is Hungary's only operating nuclear power plant, generating approximately half of the country's total electricity. Earlier announcements had mentioned that, due to the extremely low Danube water level, shutdowns of some units at the plant had become difficult to avoid.

Six radiation monitoring posts in Kumamoto Prefecture, Japan, resumed transmission on the morning of the 30th after being interrupted by power outages caused by the earthquake
Radiation monitoring stations in Kumamoto Prefecture, Japan, have resumed operations after data interruptions caused by the earthquake. On the morning of July 30, data transmission at all monitoring stations returned to normal. The initial cause of the malfunction is believed to be power outages resulting from the earthquake, and the Nuclear Regulation Authority of Japan will conduct further investigations into the matter. A total of six radiation monitoring stations are located in Kumamoto Prefecture, distributed across Kumamoto City, Uto City, and other areas, used for real-time measurement of radiation levels in the environment. Starting around 11 p.m. on July 28, data transmission from these stations was suddenly interrupted, making it impossible to assess local radiation levels. This situation drew significant attention from relevant authorities. According to the Nuclear Regulation Authority of Japan...

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.
