Carbon Nanotubes Can "Remember" Their Initial Structure, Isotope Labeling Reveals Dynamic Growth Process

A study released on September 1 shows that carbon nanotubes can maintain their initial atomic structure in dynamically changing growth environments. The research team used digital isotope labeling technology to encode the elongation process of individual carbon nanotubes as sequences of different carbon isotope compositions, and read their growth history through Raman spectroscopy, thereby tracking the structural stability of nanotubes under conditions of temperature variation and catalyst evolution. The properties of carbon nanotubes are highly dependent on their atomic arrangement. The same material may exhibit metallic or semiconducting characteristics due to structural differences, so structural uniformity has always been a key issue for the large-scale application of carbon nanotubes. In floating catalyst chemical vapor deposition and other industrial production routes, catalyst particles experience constantly changing temperatures and gas compositions within the reactor and may undergo irreversible enlargement. Previously, direct evidence was lacking on whether individual carbon nanotubes could maintain their initial structure under such complex conditions.

Japanese Team Develops High-Temperature, High-Pressure Isotope Ratio Analysis Method for Tracing Halogenated Pollutants

Researchers from Shibaura Institute of Technology (SIT) and the National Institute of Advanced Industrial Science and Technology (AIST) in Japan have collaboratively developed a customized high-temperature, high-pressure combustion interface for liquid chromatography-isotope ratio mass spectrometry (LC-IRMS), enabling carbon stable isotope ratio (δ¹³C) analysis of various halogenated organic compounds. The research findings were published online on August 2, 2026, and will appear in Volume 1421 of Analytica Chimica Acta, scheduled for release on November 1, 2026. Source of the new high-temperature, high-pressure LC-IRMS system: Professor Hiroto Kawashima, SIT, Japan. Halogenated organic compounds are widely present in disinfection byproducts, pesticides, refrigerants, and industrial chemicals, some of which exhibit persistence, bioaccumulation, and toxicity. Traditional environmental monitoring primarily relies on concentration measurements, which makes it difficult to directly provide information on pollutant sources and environmental transformation processes. δ¹³C analysis can offer clues for studying chemical sources, production processes, and environmental fate, but organic pollutants containing strong carbon—chlorine or carbon—fluorine bonds are difficult to fully oxidize under conventional LC-IRMS combustion conditions, limiting the application of this technique.

NuScale Completes First Manufacturing of Boron Carbide Pellets for SMR Safety Component in the U.S.

NuScale Power and MillenniTEK recently announced that they have successfully manufactured the first batch of boron carbide pellets for NuScale's passive emergency core cooling system (ECCS). This component will be used in NuScale's small modular reactor (SMR) technology and is one of the dedicated components in its reactor safety system. According to reports, in nuclear power plants employing NuScale technology, when the emergency core cooling system is activated, the boron carbide pellets dissolve into the reactor coolant, helping to control and maintain core reactivity at safe levels without operator intervention. This manufacturing effort is considered a key advancement in NuScale's preparation for commercial deployment, involving the validation of dedicated safety components and associated manufacturing processes.

Japan's Tomari Nuclear Power Plant Plans New Low-Level Radioactive Waste Processing Facility

Hokkaido Electric Power Company (HEPCO) recently announced plans to construct a new low-level radioactive waste processing facility within the premises of the Tomari Nuclear Power Plant in Hokkaido, Japan, to handle approximately 12,000 drums of low-level radioactive waste currently stored on site. According to HEPCO, the new facility will sort waste such as paper and metal, reduce its volume through fine shredding or compression, and then solidify it by pouring mortar into the waste drums. After processing, the waste will undergo radioactivity level testing before being transported to the disposal center in Rokkasho Village, Aomori Prefecture. Previously, the Tomari plant had stored this type of waste in 200-liter drums without further processing. The proposed facility will have an annual processing capacity of over 1,000 drums, feature a three-story structure, and cover a total floor area of approximately 4,600 square meters.

South Korea's Nuclear Safety Regulatory Budget for 2027 Rises to KRW 303 Billion

The Nuclear Safety and Security Commission (NSSC) of South Korea announced on September 1 that it has allocated KRW 303 billion for the 2027 budget, an increase of KRW 10.4 billion from this year. The new budget focuses on areas such as small modular reactor regulation, spent nuclear fuel safety, nuclear facility decommissioning review, environmental radiation monitoring, and nuclear safety information disclosure. Regarding small modular reactors, as non-light water reactor-type small modular reactor development projects aim to obtain licenses by the early 2030s, South Korea will invest KRW 8 billion in R&D to establish a new safety evaluation system. In addition, in line with the preliminary review system set to take effect in November this year, the government has allocated KRW 2.7 billion to conduct preliminary reviews of non-light water reactor-type small modular reactors expected to file applications next year. This system allows applicants to request regulatory review of reactor designs before formally submitting license applications.
