Rare Germanium Isotope Infrared Spectral Signatures Elucidated in Detail for the First Time

The press service of the Russian Ministry of Education and Science reported on August 25 that scientists from Tomsk Polytechnic University, in collaboration with an international research team, have for the first time conducted a detailed study of the infrared spectra of two rare germanium isotopes and identified characteristic spectral signatures that can be used to recognize the relevant isotopes in complex gas mixtures. The research team selected two highly enriched isotopes—germanium-72 and germanium-73—as the subjects of the study, recording their spectral information using a high-resolution Fourier transform spectrometer. This instrument is capable of resolving closely spaced spectral lines, providing the conditions for analyzing subtle spectral changes induced by isotopic substitution. The researchers stated that precise spectral data for different germanium isotopes remain relatively scarce in the scientific literature, and such data are of significant importance for identifying molecules in planetary atmospheres and for producing ultra-pure germanium isotopes for quantum technologies and modern electronics.

Russia's Rostov NPP Releases Chlorella into Cooling Pond to Strengthen Ecological Control

Russia's Rostov NPP recently carried out its annual ecological control operation at the plant's technical reservoir, releasing 3.6 tonnes of a bioactivator based on the planktonic algae chlorella into the water to suppress the risk of algal blooms and maintain the ecological balance of the cooling pond. Rostov NPP is part of Rosenergoatom, the power generation division of Russia's State Atomic Energy Corporation (Rosatom). The operation is part of the plant's long-standing algae management measures, primarily aimed at stabilizing water conditions under climate change and abnormally high temperatures, ensuring the smooth operation of related equipment. Chlorella acts as a natural biofilter, capable of suppressing...

U.S. Submits Civil Nuclear Agreement with Saudi Arabia to Congress for Review

U.S. government officials said on August 25 that President Donald Trump has submitted a proposed civil nuclear energy agreement with Saudi Arabia to Congress for review. The agreement, reached in July this year, includes provisions allowing U.S. companies to export civil nuclear technology to Saudi Arabia. Under the relevant procedures, Congress will have 90 session days to review the agreement. Two congressional sources said the agreement has been submitted to congressional leadership and is expected to be referred to relevant committees for consideration. If Congress raises no objections within the specified period, the agreement will enter into effect; if Congress rejects the agreement, Trump may still exercise his veto power, and Congress would need a two-thirds majority to override the presidential veto...

Singapore team develops deuterated silicon nitride waveguides for wafer-scale broadband light generation

A research team from the Singapore University of Technology and Design and the Institute of Microelectronics at the Agency for Science, Technology and Research (A*STAR) in Singapore has recently developed a low-loss deuterated silicon nitride waveguide capable of on-chip broadband light generation. By replacing hydrogen with its heavier isotope deuterium, the team fabricated silicon nitride waveguides at low temperatures, demonstrating potential for integration with CMOS-compatible semiconductor processes and wafer-scale mass production. The related paper, "Octave-spanning supercontinuum generation in wafer-scale low-loss deuterated silicon nitride waveguides," was published in *Optics Letters*. The study shows that this chip-scale waveguide can broaden infrared laser pulses to cover a spectral range from visible red light to deep infrared. Traditionally, silicon nitride thin films are grown from silane gas, and residual silicon-hydrogen bonds in the material absorb light in the telecommunications band, requiring high-temperature annealing that is incompatible with integrated electronic circuits.

TU Delft participates in innovative projects on compact reactors and molten salt reactors

The MOOI Kernenergie nuclear funding programme, operated by the Netherlands Enterprise Agency (RVO), has recently selected four innovative projects to support research and development in reactor and fuel cycle technologies, radioactive waste storage, and geological disposal solutions. TU Delft is involved in three of these projects, with researchers from its Reactor Institute participating in the MARLIN and PRONTO projects. The MARLIN project focuses on compact modular high-temperature gas-cooled reactors (HTGRs) for industrial, maritime, and offshore applications. Based on measurement data and models, the project consortium will develop and validate a reactor prototype capable of simultaneously providing electricity and high-temperature process heat, with a focus on industrial clusters as well as maritime and offshore scenarios.

South Korea Develops AI Model for Prioritizing Post-Earthquake Inspections at Nuclear Facilities

A joint research team from the Korea Research Institute of Standards and Science (KRISS) and Ulsan National Institute of Science and Technology (UNIST) has developed a deep learning model that can assist nuclear facilities in rapidly identifying priority inspection areas after an earthquake. The model uses seismic wave signals collected from a single seismometer to predict in real time the vibration responses at multiple locations within a nuclear power plant and quantitatively ranks potential risks. The research was jointly conducted by the team of Jae-Beom Lee, senior researcher at KRISS, and Young-Ju Lee, professor at UNIST. The researchers stated that this technology can, without installing sensors at every critical location...

Zaporizhzhia Nuclear Power Plant Loses External Power for Six Days

On August 25 local time, the Zaporizhzhia Nuclear Power Plant (ZNPP) stated that it had lost external power since August 20 and had been relying on backup diesel generators to meet on-site electricity demand for six consecutive days. The plant's existing fuel reserves can still ensure operation, but difficulties in fuel resupply have not yet significantly eased. Yevgeniya Yashina, head of communications at ZNPP, stated that plant staff are monitoring nuclear safety parameters and the operation of backup diesel generator units around the clock. She noted that fuel transportation still faces difficulties due to shelling on roads leading to the plant; to improve the efficiency of existing reserve utilization, the plant has optimized the operation of diesel generators...

Japan's Mihama Nuclear Power Plant Unit 3 Receives Preliminary Approval for Operation Plan Beyond 50 Years

On August 25, Japan's Nuclear Regulation Authority (NRA) gave preliminary approval to Kansai Electric Power Co. (KEPCO) for the long-term facility management plan for Unit 3 of the Mihama Nuclear Power Plant. Located in Mihama Town, Fukui Prefecture, the unit will mark its 50th anniversary of commercial operation on December 1. In May of this year, the metal top cover of the high-pressure turbine at Mihama Unit 3 suffered damage, resulting in steam leakage. At the NRA meeting held that day, KEPCO explained that the cause of the incident was believed to be thinning of the inner wall of the top cover due to steam flow. The company stated that this phenomenon falls under previously anticipated aging and degradation management for turbine equipment, and that the existing plan already includes corresponding management measures. Visual inspection and other examination methods were also deemed applicable, thus no revision to the long-term facility management plan was required.
