Steel Dome of Unit 1 at Liaoning Xudabao Nuclear Power Plant Hoisted into Place

On August 28, the steel dome of the nuclear island of Unit 1 at Liaoning Xudabao Nuclear Power Plant, invested and controlled by China National Nuclear Corporation (CNNC)'s China National Nuclear Power, was hoisted into place, marking that the large steel structure module construction of the unit has entered its final stage and laying a solid foundation for achieving the milestone of structural completion of the nuclear island buildings. As the core load-bearing structure of the nuclear island, the steel dome sits atop the steel-plate concrete structure, bearing all loads from the passive containment cooling water storage tank and the structures above. It serves as a critical barrier safeguarding the structural integrity and sealing reliability of the reactor building. The dome is conical in shape, composed of radial main beams, ring beams, steel cladding panels, and a bottom steel platform, with a diameter of approximately 41 meters, a height of 11 meters, and a total hoisting weight of nearly 1,000 tons...

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...

Hualong One Pressurizer Electric Heaters Achieve Coverage of Two Major Technical Routes

The pressurizer electric heater is an important safety-class component of the reactor coolant system (primary loop) in pressurized water reactor nuclear power plants, directly affecting unit pressure regulation and safe, stable operation. The localized pressurizer electric heater developed by Chuanyi Instrument Co., Ltd., a subsidiary of SINOMACH Instrumentation Group under SINOMACH Group, has been applied to China's self-developed Generation III nuclear power units such as "Hualong One." The photo shows the qualification prototype of the Hualong One pressurizer electric heater. With the batch construction of Hualong One units advancing, units adopting different technical routes have imposed new customized operating condition requirements on pressurizer electric heaters. In October 2019, Chuanyi Instrument, together with China General Nuclear Power Engineering Co., Ltd., initiated the development of the CGN-version Hualong One pressurizer electric heater...

Novartis Files Localized Production Application in China for Lutetium [177Lu] Vipivotide Tetraxetan

On August 24, information on the website of the Center for Drug Evaluation (CDE) of China's National Medical Products Administration showed that Novartis' nuclear medicine product Lutetium [177Lu] Vipivotide Tetraxetan had a localized production application submitted in China. On the same day, two indications for the drug were proposed for priority review, and the relevant review matters may correspond to this localized production application. Lutetium [177Lu] Vipivotide Tetraxetan, namely 177Lu-PSMA-617, is a radioligand therapy (RLT) drug acquired by Novartis following its acquisition of Endocyte. The drug consists of a small-molecule compound targeting prostate-specific membrane antigen (PSMA) conjugated to the therapeutic radionuclide Lutetium-177. Upon entering the bloodstream, the drug binds to prostate cancer cells expressing PSMA, and...

France Authorizes CEA to Dismantle the Pégase Research Reactor Facility at Cadarache

The French Official Journal published a decree on August 23 authorizing the French Alternative Energies and Atomic Energy Commission (CEA) to carry out dismantling operations on the Pégase (Pégase) nuclear facility located at the Cadarache site in Saint-Paul-lès-Durance, Bouches-du-Rhône department. The facility is classified as Basic Nuclear Installation No. 22 (INB 22). The decree specifies the implementation phases for the partial dismantling of the Pégase research reactor and authorizes the CEA to build the equipment required for the dismantling operations. Under the decree, the boundaries of the Pégase facility will be adjusted to provide the necessary space for the layout of dismantling equipment and the temporary storage of waste generated during the dismantling process. The dismantling scope covers the Pégase facility itself, including the main building housing the storage and treatment...

Russian Scientists Propose New Scheme for Measuring Proton and Deuteron Electric Dipole Moments in a Single Storage Ring

August 21 news, researchers from the Moscow Institute of Physics and Technology, the Institute for Nuclear Research of the Russian Academy of Sciences, the National Research Nuclear University MEPhI, and the Landau Institute for Theoretical Physics of the Russian Academy of Sciences have proposed a new experimental scheme to study the electric dipole moments of protons and deuterons in a single storage ring. The scheme can be implemented both in specially constructed new facilities and, potentially, in upgraded existing accelerator complexes. The electric dipole moments of protons and deuterons reflect the asymmetry of the internal charge distribution relative to the spin direction. According to Standard Model predictions, their values are non-zero but extremely small, on the order of 10⁻³¹ e·cm, far below current experimental sensitivity...

CERN Large Hadron Collider Data Challenge Models of Oxygen and Neon Nucleus Structure

Physicists at the European Organization for Nuclear Research (CERN), analyzing a new batch of collision data from the CMS detector at the Large Hadron Collider, have found that oxygen and neon nuclei do not behave entirely as predicted by existing models in high-energy collisions. This result indicates that the scientific community's understanding of the shapes and internal structures of certain light nuclei still requires further refinement. In high-energy nuclear collisions, a quark-gluon plasma is briefly formed in the collision region. This state of matter decays rapidly, but the collective flow characteristics of its particles can be used to infer the collision geometry and indirectly provide information about nuclear structure. Researchers believe that symmetric collisions of light ions help better control the initial collision conditions, making them suitable for studying collective responses in small systems.

Indian private enterprises lean toward 700 MWe pressurized heavy water reactors to enter nuclear power market

As India plans to significantly expand its nuclear power capacity, the domestically developed 700 MWe pressurized heavy water reactor (PHWR) is emerging as the primary choice for new entrants in the country's civilian nuclear power sector. Industry players believe this reactor type has established a relatively mature design, supply chain, and engineering service system, making it more suitable as a starting point for private enterprises to enter the nuclear power field. India has proposed increasing its domestic civilian nuclear power capacity to 100 GWe by 2047. Recently, India released the draft rules for the SHANTI Act, establishing a regulatory framework for a broader nuclear power ecosystem, covering private participation, captive power generation, licensing management, safety oversight, and nuclear liability. At an energy summit held in New Delhi...
