Zhangzhou Nuclear Power Unit 4 Completes Hoisting of Four Internal Structure Modules
From August 18 to 27, CNNC 24 completed the hoisting of four concrete modules for the internal structure of Zhangzhou Nuclear Power Unit 4 within 10 consecutive days, covering the evaporator compartments of Loops 3, 2, and 1 as well as the pressurizer compartment, creating conditions for subsequent loop installation and commissioning work. The evaporator and pressurizer are key equipment in the nuclear island loops. The corresponding compartment concrete modules serve both load-bearing fixation and protection functions, representing an important embodiment of the "Hualong One" defense-in-depth safety philosophy at the civil construction stage. The four modules hoisted this time are all irregularly shaped structures, all adopting the "off-site prefabrication + integral modular hoisting" process, with a total hoisting weight of approximately 2,400 tons. Compared with Unit 3, Unit 4 achieved 3...

Argonne National Laboratory Measures Dust Resuspension Behavior in Radioactive Contamination Scenarios
Researchers at the U.S. Department of Energy's Argonne National Laboratory recently conducted field experiments to simulate the movement of dust particles on concrete surfaces under radioactive contamination scenarios, measuring the effects of pedestrian activity and vehicle traffic on dust dispersion. The study was published in the journal Health Physics and received support from the U.S. Department of Homeland Security Science and Technology Directorate and the Radiological/Nuclear Emergency Response and Recovery Research and Development Program. To control humidity and temperature and prevent dust generation, pedestrian tests were conducted inside a tent. In the image, researchers can be seen entering the tent on the left. Particle counters are placed on a white table, with their hoses extending into the tent to collect air samples. (Image courtesy of Ar...

Czech nuclear power plants largely unaffected by summer heat and drought
The Czech State Office for Nuclear Safety (SÚJB) stated on August 26 that this summer's heat waves and drought only caused a slight decline in electricity generation at the Temelín and Dukovany nuclear power plants, without leading to reactor power reduction or raising nuclear safety concerns. Currently, both plants meet the conditions for safe operation, including adequate cooling and water supply guarantees. SÚJB noted that some European nuclear power plants reduced output or temporarily shut down during high-temperature periods, mainly due to their cooling methods. Some plants use once-through cooling, making their operation directly affected by river water temperature and flow rate. When water temperatures rise and river flows are low, plants may reduce output due to environmental discharge limits...

France's Gravelines Nuclear Power Plant Reports Multiple INES Level 0 Events
France's Gravelines nuclear power plant recently disclosed significant events reported to the French Nuclear Safety and Radiation Protection Authority (ASNR). The events cover safety, operations, and radiation protection, and were all rated as Level 0 on the International Nuclear and Radiological Event Scale (INES), i.e., below the scale threshold, with no actual impact on facility safety, personnel health, or the environment. In a generic safety event involving EDF's 900 MWe-class nuclear reactor units, EDF discovered during inspections at the Cruas nuclear power plant that certain commercially supplied electric servomechanisms had been installed in functional positions requiring higher qualification levels, K3 or K3ad. K3 corresponds to seismic requirements, while K3ad involves both seismic and harsh environmental conditions, including radiation environments. Subsequently, EDF conducted checks on related equipment at the Blayais, Chinon, Cruas, Dampierre, Gravelines, Saint-Laurent, and Tricastin nuclear power plants and confirmed that a batch of equipment had model suitability issues.

Ikata Nuclear Power Station Unit 3 in Japan briefly deviated from operational limits due to abnormal signals in protection system instrumentation
Shikoku Electric Power Co. reported on August 27 that abnormal signals from safety protection system instrumentation appeared in the central control room of Ikata Nuclear Power Station Unit 3, which was in normal operation, indicating that one channel of the overtemperature ΔT related instrumentation was unreliable. The operator determined at 22:10 on August 26 that the unit had deviated from the operational limits stipulated in the Reactor Facility Security Regulations. On-site confirmation showed that the unreliable signal originated from 1 of the 4 channels of the overtemperature ΔT protection function. Overtemperature ΔT is one of the reactor automatic trip elements, used to protect in-core fuel; its limit value is calculated based on parameters such as reactor power, pressurizer pressure, and...

Canada's Nuclear Energy Strategy Focuses on Project Financing and Risk Sharing
The Canadian federal government recently unveiled a new nuclear energy strategy, explicitly committing to advancing new nuclear power projects nationwide, strengthening domestic supply chains, expanding uranium resources and nuclear fuel supply, and continuing to support nuclear technology innovation in fission and fusion. The strategy also states that nuclear deployment requires more modern financing tools, more efficient regulatory processes, and closer collaboration among governments, Indigenous communities, and industry. The goal of this strategy is to serve Canada's economic, social, and climate objectives through nuclear energy projects, enhancing national energy security while creating jobs and fostering innovation. As the strategic direction becomes clearer, how to translate policy goals into projects that are financeable and ready for construction has become the key question for the next phase.

Europe Advances Space Nuclear Power Research, Targeting Lunar and Mars Missions
The European Space Agency (ESA) is accelerating its assessment of nuclear energy applications in deep-space missions, focusing on using small nuclear reactors to power spacecraft electric propulsion systems, as well as providing stable energy for future fixed lunar surface facilities and subsequent Mars missions. Existing space missions primarily rely on chemical fuels and solar panels. The former is limited by the amount of propellant that can be carried, while the latter suffers from declining power generation efficiency as spacecraft move farther from the Sun. ESA believes that nuclear power systems could compensate for the shortcomings of both approaches, particularly in long-duration lunar operations and deeper space exploration. ESA completed a nuclear thermal propulsion study last year. In March this year, the agency...

Huzhou, Zhejiang Launches Phase I "Drug-Device Combination" Clinical Trial for the Province's First BNCT System
Recently, the Boron Neutron Tumor Treatment Center at Huzhou Hospital Affiliated to Zhejiang University School of Medicine has drawn attention with the introduction of the province's first Boron Neutron Capture Therapy (BNCT) system. Previously, the system had already initiated a Phase I BNCT drug-device combination clinical trial. According to the system developer, Huapeng Neutron Technology (Hangzhou) Co., Ltd., BNCT is a radiotherapy technique combining drugs and devices, with its core lying in the coordinated use of boron-containing drugs and neutron irradiation. After entering the human body, the boron-containing drug can be absorbed by tumor cells; subsequent neutron beam irradiation triggers a localized reaction to achieve targeted radiotherapy against tumor cells. Unlike conventional radiotherapy, which typically employs fractionated irradiation over a longer treatment course, BNCT emphasizes selective targeting of tumor cells, aiming to reduce damage to surrounding healthy tissues and lower radiotherapy-related side effects such as hair loss and immunosuppression.
