Radioactive liquid waste leak suspected at QST's underground facility in Chiba due to record rainfall

According to Japanese media reports, due to record-breaking rainfall in Chiba Prefecture, an underground facility of the National Institutes for Quantum Science and Technology (QST) in Chiba City was flooded, and radioactive liquid waste in underground storage tanks at the facility may have mixed with rainwater and leaked outdoors. QST stated that as of the 13th, an estimated 2,000 to 3,000 liters of liquid waste had accumulated in the relevant underground storage tanks. After investigating water bodies around the tanks, the institute confirmed that detected radioactive material concentrations were below standard values, and no environmental impact has been indicated so far. QST reported the incident to national and local governments the following day and plans to submit preventive measures to the Nuclear Regulation Authority of Japan.

Safety measure costs after Japan's nuclear plant accident rise to at least 6.606 trillion yen

A survey of 11 Japanese electric power companies shows that the total cost of safety measures required for nuclear plants to meet new regulatory standards following the Fukushima Daiichi accident has reached at least 6.606 trillion yen. Affected by rising prices, this figure has increased slightly from the previous year. About half of the surveyed companies said that rising costs of materials, equipment, and construction have pushed up related expenses, and the total may continue to rise in the future. After the Fukushima Daiichi accident, Japan implemented new nuclear regulatory standards requiring plants to strengthen earthquake and tsunami protection and improve severe accident response measures. Related costs mainly include seawalls, emergency power supplies, filtered venting equipment, and...

Huaneng Nuclear Energy Research Institute Conducts First Specialized Training on Hualong One System Principles

To enhance the Institute's technical support services and scientific research capabilities regarding Hualong One technology, and to strengthen employees' systematic understanding of Hualong One, Huaneng Nuclear Energy Research Institute organized training on Hualong One system principles, completing the first specialized session on August 12. A total of 101 company leaders and employees participated in the training through a combination of online and offline methods. The first training session reviewed China's path toward independent development of pressurized water reactor technology from an industry development perspective, systematically outlining the global evolution of nuclear power technology and the safety design criteria for Generation III nuclear power. By benchmarking against mainstream Generation III reactor designs such as the US AP1000 and European EPR, the session provided in-depth explanations of Hualong One's dual safety architecture combining active and passive safety systems...

CMS Experiment Advances Higgs Boson Pair Search with New Data

The CMS Collaboration has recently announced new progress in the study of Higgs boson pair production. The study is based on proton collision data at a center-of-mass energy of 13.6 TeV recorded by the CMS detector from 2022 to 2024, focusing on the search for processes where one Higgs boson decays to a bottom quark–antiquark pair and the other decays to a τ lepton–antitau pair, namely the HH→bbττ channel. Since the discovery of the Higgs boson in 2012, the CMS and ATLAS Collaborations have continuously measured the interactions of the Higgs boson with other Standard Model particles, and the results so far remain generally consistent with Standard Model predictions. In contrast, the “self-coupling” among multiple Higgs bosons...

Korean Hospital Team Develops AI Model to Improve Bone Metastasis Detection Using PET/CT and Other Information

A research team at Seoul Metropolitan Government Seoul National University Boramae Medical Center has recently developed an artificial intelligence model capable of identifying bone metastases that are difficult to detect on CT images. By incorporating MRI and PET/CT information during the training process, the model enables lesions that are inconspicuous on CT and prone to being missed to be included in the training data, thereby enhancing detection capability. Bone metastasis is an important basis for determining cancer staging and formulating treatment plans. If lesions are not clearly visible on CT images, bone metastasis may be detected late and may lead to complications such as pathological fractures and spinal cord compression. Previous related AI studies have largely relied on lesions clearly visible on CT to build training data, and the research team believes that this approach may...

The Egyptian Nuclear Power Plants Authority (NPPA) recently announced that installation of the fifth tier of the inner containment shell in the reactor building of Unit 1 at the El Dabaa Nuclear Power Plant has commenced. This marks a significant milestone in the civil construction and installation work for the unit. The inner containment shell is a cylindrical structure designed to house the nuclear reactor and related primary circuit equipment of the nuclear power plant. The fifth tier being installed consists of 12 components, all prefabricated on-site at the El Dabaa plant. Each component is 7.5 meters high and weighs approximately 40 to 45 tons, depending on its structural configuration. As planned, the installation of the fifth tier is expected to be completed within two weeks. Subsequently, the remaining tiers will continue to be assembled to form the complete annular inner containment structure. A heavy-duty crane with a lifting capacity of 2,200 tons will be used for the lifting operations at the construction site...

Danube Water Levels Continue to Drop, Hungary's Paks Nuclear Power Plant May Reduce Output Again

Hungary's Paks Nuclear Power Plant may reduce its power generation output again early next week due to the continued decline in Danube water levels. Péter Magyar stated on social platform X that Tuesday and Wednesday will be critical periods, with the Danube water level expected to drop by another 14 to 15 centimeters, while the current level is only 9 centimeters away from the threshold that would force the shutdown of the second-to-last turbine at the Paks plant. Magyar noted that this critical phase is expected to end on August 20, when the water level in the Hungarian section of the Danube is expected to recover, influenced by inflows from the Austrian catchment area. Previously, on August 12, Magyar stated that the Hungarian government had decided to build temporary water-retention structures near the Paks Nuclear Power Plant and sink two barges to raise local water levels and ensure the plant's water intake conditions.
