Finland's Loviisa Nuclear Power Plant Launches Turbine Island Upgrade to Support Operation Until 2050
Finnish utility Fortum has launched a large-scale modernization project for the turbine island at the Loviisa Nuclear Power Plant. The project aims to increase the plant's electrical output and ensure the continued, safe, and reliable operation of both units through the end of 2050 under the new operating licenses. The Loviisa plant consists of two VVER-440 pressurized water reactor units and is Finland's first nuclear power plant, currently supplying more than 10% of the country's electricity. Unit 1 entered commercial operation in 1977, followed by Unit 2 in 1981, and the Finnish government approved the extended operating licenses in February 2023. The core of this upgrade is the modernization of the low-pressure turbines, which is the largest single undertaking in the Loviisa turbine island upgrade...

Unit 2 of Leningrad Nuclear Power Plant Phase II automatically shut down for equipment maintenance
At 21:45 local time on August 8, 2026, Unit 2 of Leningrad Nuclear Power Plant Phase II was shut down by the automatic system due to the need for thermal-mechanical equipment maintenance. After the maintenance work is completed, the unit will be reconnected to the grid. The shutdown was carried out in accordance with established procedures and design logic. The plant reported no violations of safe operation limits or operating conditions for any of the units. Currently, RBMK-1000 Units 3 and 4 of Leningrad Nuclear Power Plant, as well as Unit 1 of Phase II, are operating normally and carrying electrical loads in accordance with the dispatch schedule. RBMK-1000 Units 1 and 2 are in the preparation stage for decommissioning...

Hungary's New Government Questions Paks II Nuclear Project, Audit Dissatisfaction May Lead to Contractor Replacement
Hungary's new government (Prime Minister Péter Magyar) has continued to send unclear signals regarding the Paks II nuclear power plant expansion project contracted to Russia's Rosatom, bringing this major energy project involving the Russian state nuclear corporation back into the spotlight. The government is dissatisfied with the interim results of the contract audit and has hinted that Budapest does not rule out the possibility of replacing the contractor. The Paks II project was originally regarded as a key component of Hungary's long-term energy security strategy. Nuclear power holds fundamental significance for Hungary's electricity supply, and the expansion of the Paks nuclear plant was also seen as a measure to reduce energy import pressure and stabilize electricity prices.

PETRA III Synchrotron Radiation Study Reveals New Clues to Aging Mechanisms of the Uterine Broad Ligament
Austrian and German research teams recently used the PETRA III facility at the German Electron Synchrotron (DESY) to conduct X-ray analysis of the broad ligament, an important ligament supporting the uterus, providing new biomechanical clues for understanding the mechanisms of pelvic organ prolapse. The findings were published in *Acta Biomaterialia*. Pelvic organ prolapse is a common but poorly understood issue in women's health, affecting approximately 40% of women, and predominantly occurring in the latter half of life. Medical researchers have previously speculated that age-related loosening of the ligaments surrounding the uterus may be a significant contributing factor to prolapse. The broad ligament connects the uterus to the pelvic wall, and its strength and elasticity primarily derive from collagen...

Danube Water Level Temporarily Recovers, Hungary's Paks Nuclear Power Plant May Continue Reduced-Power Operation
Hungarian Prime Minister Peter Magyar said on August 7 that due to rainfall in Austria, the Danube water level is expected to temporarily recover in the near term, which will help improve cooling conditions at the nuclear power plant, but the Paks Nuclear Power Plant, which supplies nearly half of Hungary's electricity, may still continue to operate at reduced power. In a social media video, Magyar said the current situation at the Paks Nuclear Power Plant remains very difficult. Affected by persistent high temperatures and historically low Danube water levels, the plant has been operating at approximately 10% output since last week. At a subsequent press conference, he stated that Hungary must find a solution for the operation of the Paks Nuclear Power Plant, because "the Hungarian economy cannot function for months without the plant." Previously, the government had called on businesses and residents to reduce electricity consumption in the evening and dim the decorative lighting of historic buildings in Budapest to alleviate power supply pressure.

Rosatom Completes First Batch of Certification for Energy Critical Information Infrastructure Products
Rosatom has recently completed the first batch of product certification for critical information infrastructure in the fuel and energy sector under the KII-Sert voluntary certification system. The certification system has been operating in Russia's nuclear energy and aerospace industries since 2024, primarily used to assess the reliability, technological independence, and sustainability of solutions related to critical information infrastructure. The certification was carried out by Atomenergoproekt JSC, part of Rosatom's engineering division. As an authorized certification body for trusted products and processes within the KII-Sert system, the company, in cooperation with the industrial testing laboratory Avtomatika-Servis LLC, certified a software and hardware system used in the oil and gas industry.

New Decommissioning Plan for Fukushima Daiichi: Priority on Internal Investigation of Unit 3 Before Fuel Debris Retrieval
The Nuclear Damage Compensation and Decommissioning Facilitation Corporation of Japan released on August 6 an outline of the 2026 edition of the "Decommissioning Strategic Plan," proposing technical approaches for the decommissioning of Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station. The plan highlights that, for the large-scale retrieval of melted fuel debris at Unit 3, expected to commence in or after fiscal year 2037, priority should currently be given to internal investigations of the reactor building to provide a more reliable basis for subsequent engineering plans. The plan states that the fuel debris retrieval method being studied by TEPCO still requires further improvement in certainty, with the key prerequisite being an understanding of the actual internal conditions of the reactor. Due to the high radiation levels of the water inside the unit following the accident...

BESIII Experiment First Confirms the Existence of Glueballs
On August 6, Beijing time, the international collaboration of the Beijing Spectrometer III experiment (BESIII) at the Beijing Electron-Positron Collider announced at the International Conference on High Energy Physics (ICHEP 2026) held in Brazil, in the form of a special plenary report: after 15 years of sustained research, the BESIII experiment has established a complete chain of evidence proving the existence of glueballs, unraveling the mystery that has puzzled the academic community for nearly half a century. This discovery not only provides a decisive validation of the theory of quantum chromodynamics, but also demonstrates the existence of a completely new form of matter—matter composed purely of force. Atomic nuclei are composed of protons and neutrons, which in turn are composed of quarks. Gluons mediate the strong interaction between quarks...

Construction of inner containment begins at Unit 4 of Leningrad Nuclear Power Plant II
Construction of the inner containment of the reactor building at Unit 4 of the Leningrad Nuclear Power Plant II in Russia has commenced. The unit features a VVER-1200 reactor, and the inner containment is a key component of the unit's passive safety system, as well as part of the plant's confinement safety system. Construction workers have installed the first tier of vertical sealed steel liner to its design position. The steel structure weighs approximately 97 tonnes, and the lifting and positioning operations were carried out using a heavy crawler crane, with the entire installation process lasting about 7 hours. The contractor, TITAN-2 Holding Company, stated that the preparatory work took several months, including component fabrication, protective coating application, on-site assembly and welding, and structural quality inspection...
