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...

Japan's Fukushima Daiichi Nuclear Power Station launches 22nd release of radioactive wastewater into the ocean, approximately 7,800 tons this time

On the morning of July 30, 2026, Tokyo Electric Power Company (TEPCO) initiated a new round of nuclear-contaminated water discharge into the ocean at the Fukushima Daiichi Nuclear Power Station. This marks the 4th release within 2026 and the 22nd since the discharge plan began in August 2023. According to data released by TEPCO, this discharge is expected to continue until the 17th of next month, with a total volume of approximately 7,800 tons. The total amount of radioactive substance tritium contained therein is as high as approximately 1.3 trillion becquerels. Prior to this, Japan had conducted a total of 21 rounds of radioactive wastewater discharge by the 24th of this month, with a cumulative discharge volume reaching approximately 165,000 tons.

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.

QST completes first gyrotron 170 GHz microwave output test at ITER site

The National Institutes for Quantum Science and Technology (QST) of Japan announced on July 31 that it has completed the integration and operational testing of the first gyrotron system at the International Thermonuclear Experimental Reactor (ITER) site in southern France, successfully producing 170 GHz microwave output. This system is used for ITER plasma generation and heating, and is one of the key devices for ITER's plan to commence operations in 2034. The core equipment of this test is the gyrotron, a high-power microwave source. Gyrotron operation requires the coordinated work of peripheral equipment such as power supplies, superconducting coils, and cooling systems. QST previously completed performance testing of eight ITER gyrotron systems at the gyrotron test facility of the Naka Fusion Institute in Japan, and transported components including gyrotrons, superconducting coils, and quasi-optical matching units to the ITER site. Over the past three years, QST has advanced system installation, commissioning, and operational preparation at the site.
