Under the protection of the latest localized ceasefire negotiated by IAEA DG @rafaelmgrossi, repairs have been completed on power infrastructure that is of crucial importance for efforts to prevent a nuclear accident during the conflict in Ukraine. The eighth such IAEA-brokered temporary truce took effect on 15 October, paving the way for the past week’s repairs of damaged electrical switchyard equipment , around 2 km from the Zaporizhzhya Nuclear Power Plant (ZNPP) and a key link in its access to off-site power. The work - conducted near the frontline and monitored by an IAEA team - was at times accompanied by the sound of drones, gunfire and other military activity, stark reminders of constant dangers to nuclear safety and security. The successful repairs have strengthened the connection between the ZNPP and its sole remaining external power line, the Ferosplavna-1, and reduced the risk of yet another loss of off-site power for Europe’s largest nuclear power plant. The ZNPP’s connection to the electrical grid is especially important at this time as the site’s fuel reserves for emergency diesel generators have declined in recent months, potentially weakening its ability to cope with another lengthy loss of the external electricity needed for reactor cooling and other essential nuclear safety and security functions. DG Grossi thanks the Russian Federation and Ukraine for agreeing to the ceasefire and paving the way for the repairs, demonstrating a readiness by both sides to engage constructively with the IAEA for the sake of nuclear safety and security. The IAEA will continue its vital work to help protect the ZNPP and other nuclear installations during the conflict, DG Grossi adds.

Nitrogen pollution is an increasing threat to rivers, lakes and groundwater worldwide. Excess nitrate from wastewater discharges, agricultural activities and other human sources can degrade water quality, fuel harmful algal blooms and damage freshwater and coastal ecosystems. Yet identifying the origin of nitrate contamination is often difficult because nitrogen undergoes complex biological and chemical transformations as it moves through the environment.

Nobel laureate Ilya Mikhaylovich Frank was born today in 1908! This Russian physicist is famous for explaining Cherenkov radiation — the blue glow you see in a reactor. Frank, together with his colleague Igor Tamm, concluded in 1937 that Cherenkov radiation was the result of charged particles interacting with electrons because particles travel faster than light in an insulating medium such as water. This interaction produced the bluish light first discovered by and named after their compatriot Pavel Cherenkov three years earlier. This explanation earned Frank and Tamm the Nobel Prize in Physics in 1958.

An IAEA team of experts found that Kenya is committed to continuous improvement of the safe management of radioactive waste as it prepares to introduce nuclear power to its energy mix. The experts noted the considerable progress made in recent years and gave recommendations for the country to further develop, finalize and implement its national plan for waste management. atoms.iaea.org/4kagSnp

Today is the birthday of Clinton Joseph Davisson, the Nobel Prize-winning American physicist who discovered electron diffraction. In an experiment conducted with physicist Lester Germer, Davisson showed that, when directed at a crystal, an electron beam will produce a diffraction pattern with wave-like attributes. The Davisson-Germer experiment confirmed a similar hypothesis proposed in 1924 by Louis de Broglie, with Davisson and Lester becoming the first to demonstrate the wave properties of the electron. Their Nobel Prize-winning work proved the principle of wave-particle duality, which states that every elementary particle or quantic entity exhibits properties, not only of particles, but also waves.

“This new power…is harnessed for the first time for the common good of our community,” the Queen declared at Calder Hall in Cumberland shortly before pulling the lever that directed electricity from the world’s first full-scale nuclear power station into the national power grid. 24 kilometres north, the town of Workington became the first to receive light, heat and power from nuclear energy. The first nuclear-powered electricity spread to London within four hours. 70 years later, nuclear power continues to be a reliable and low carbon energy source that many countries are considering or have added to their energy mixes.

Scientists in Burkina Faso have used nuclear techniques to develop eight new rice varieties that yield more, mature faster and offer improved grain qualities, helping boost local food production and reduce its reliance on rice imports. Released in 2025, the varieties show how scientific innovation can move from the laboratory to farmers’ fields and, ultimately, to the food people eat. The achievement was made possible with support from the IAEA and the @FAO under the #Atoms4Food initiative atoms.iaea.org/4dIx9fl #WorldFoodDay
