Basic research cracks an application challenge that has persisted for nearly half a century: quantitative prediction of neutron irradiation swelling via ion irradiation

Whether advanced nuclear energy systems can operate safely over the long term depends on the ability of structural materials to resist neutron irradiation damage. Neutrons create numerous atomic-scale defects in materials, which gradually aggregate into nanoscale cavities, ultimately causing material swelling, dimensional instability, and performance degradation. However, obtaining high-dose neutron irradiation data often requires years or even more than a decade, with high costs and post-irradiation sample radioactivity; in contrast, ion irradiation can simulate years of accumulated damage within days and is therefore widely adopted (approximately 95% of irradiation experimental data in existing literature come from ion irradiation). But the dose rate of ion irradiation is typically 3—4 orders of magnitude higher than that of neutron irradiation, making direct conversion between the two results difficult. Recently, the research team of Wang Chenxu and Wang Yugang from the Institute of Heavy Ion Physics, School of Physics, and the State Key Laboratory of Nuclear Physics and Nuclear Technology at Peking University, in collaboration with researchers from the University of Tennessee and other institutions, established a quantitative relationship between material swelling and irradiation dose and dose rate at fixed temperatures based on cluster dynamics simulations, theoretical derivations, and ion irradiation experiments, achieving prediction of neutron irradiation swelling using rapid ion irradiation and providing a new tool for rapid screening and lifetime evaluation of nuclear materials.

FAO and IAEA: Nuclear Technologies Are Enhancing Agricultural Production and Food Security

On March 30, 2021, the Food and Agriculture Organization of the United Nations and the International Atomic Energy Agency presented multiple applications of nuclear technologies in agriculture and food security. The two organizations have collaborated for over 50 years in knowledge sharing and capacity building, further strengthening their partnership through the establishment of the Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture. In the field of animal health, nuclear technologies are used for the detection, control, and prevention of transboundary animal diseases and zoonoses. Belize previously had to send animal disease testing samples to overseas laboratories; with support from the Joint FAO/IAEA Centre, the Belize Agricultural Health Authority established a molecular diagnostic laboratory for animal health and adopted real-time polymerase chain reaction (PCR) testing technology. This method can detect animal diseases within 24 hours, helping frontline personnel take rapid prevention and control measures. Recently, the laboratory has also been used to assist in human COVID-19 testing, reflecting the "One Health" concept that animal, human, plant, and environmental health are interconnected.

IAEA Publishes Report on Aging Management of Spent Fuel Dry Storage Systems

The International Atomic Energy Agency (IAEA) has published the findings of a decade-long study on aging management of spent fuel dry storage systems. According to IAEA estimates, by the end of 2024, spent fuel discharged from nuclear power plants worldwide had exceeded 400,000 tonnes of heavy metal (tHM). Of this, 106,000 tHM is in dry storage, a long-term storage method that is becoming increasingly common compared with wet storage. Most IAEA member states are still decades away from commissioning permanent spent fuel repositories, which means dry storage systems will likely need to continue operating safely beyond their design lifetimes. Wet storage has been in operation for decades, and the IAEA states that aging management of such facilities is generally well understood. Utilities choose dry storage for its passive safety features, and many dry storage facilities have already received license extensions. The IAEA expects demand for dry storage to continue growing, with service periods extending well beyond the original 20-to-40-year licensing terms, potentially exceeding 120 years. Aging management programs (AMPs) are therefore needed to verify continued safe operation.
