Nuclear science helps reduce global food spoilage and waste

On April 10, 2026, the International Atomic Energy Agency introduced several applications of nuclear science in reducing food spoilage and food waste. According to data from the Food and Agriculture Organization of the United Nations, approximately 1 billion tonnes of edible food are wasted globally each year, accounting for about one-fifth of the total food available to consumers. Of this, 13.2% of food is lost before reaching the retail stage, valued at approximately $400 billion; another 19% is wasted at the retail and consumption stages due to spoilage and other reasons. Food loss not only means wasted resource consumption but also exacerbates greenhouse gas emissions, pollution, and biodiversity loss.

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.

MIT Develops Ultrafast X-ray Thermometry Method to Observe Heat Transfer in Multilayer Chip Structures

Researchers at the Massachusetts Institute of Technology (MIT) have developed a new method for observing how heat transfers through multilayer materials, which can be used to precisely measure heat flow variations inside electronic devices such as computer chips. The findings have been published in Nature Communications. As computer chips continue to shrink in size and power density keeps rising, device overheating has become a major factor limiting performance improvements. Traditional heat flow measurement methods face limitations when dealing with the multilayer structures of real electronic devices—for example, the commonly used time-domain thermoreflectance method struggles to distinguish heat transport in different material layers, while infrared imaging and other approaches also fail to capture rapid changes at microscopic scales. To address this issue...
