The Zaporizhzhya Nuclear Power Plant (ZNPP) was reconnected to the grid today following successful repairs of the Ferosplavna back-up power line that were carried out under the protection of an IAEA-brokered localized ceasefire. In the ZNPP’s 19th loss of off-site power during the military conflict, the plant lost the connection to the 330 kilovolt (kV) line late on Wednesday due to military-related damage, forcing it to rely on emergency diesel generators for the electricity it needs to cool its six shutdown reactors. Lasting almost three days, it was one of the site’s longest such loss of power events, underlining the extreme fragility of the electrical grid. An IAEA team monitored the repairs near the ZNPP. In other efforts crucial for nuclear safety, the IAEA is continuing to observe repair activities at the Zaporizhzhya Thermal Power Plant (ZTPP) switchyard as well as de-mining work in another frontline area close to the ZNPP to also enable repairs of the site’s main power line, the 750 kV Dniprovska, that has been disconnected since March. Both power lines and the switchyard repairs are needed to secure off-site electricity for the ZNPP and to help prevent a nuclear accident, DG @rafaelmgrossi says. DG Grossi expresses deep concern about increased military activity in recent days and weeks that is further jeopardizing key nuclear safety principles and he reiterates the necessity of maximum military restraint near all nuclear facilities. The IAEA remains committed to doing everything it can to ensure nuclear safety and security during the conflict, DG Grossi adds.

Isotope hydrology helps governments find and understand the source of their water supplies – so they can develop management systems to build resilience to drought. This World #DesertificationAndDroughtDay  we reflect on how nuclear science is helping Kenyan experts get the food and water they need from a water-scarce land. atoms.iaea.org/4uB4231

Licensing advanced reactors across borders can be challenging when regulatory requirements differ from country to country The IAEA has launched the NHSI Regulatory Cooperation Toolkit, a practical resource that supports collaboration among regulatory bodies reviewing advanced reactor designs. This Toolkit helps reduce duplication, improve efficiency and support more harmonized review processes. For regulators — better collaboration.  For Member States — more efficient reviews.  For industry — a clearer path to deployment. ➡️ Learn more and access the Toolkit: atoms.iaea.org/NHSI-Toolkit

Neutron activation analysis is a nuclear technique used by investigators to analyse criminal evidence such as a bullet. Learn how this technique works and discover other ways nuclear techniques help crime investigations via #NuclearExplained: atoms.iaea.org/475m2XI

Prostate cancer is one of the most prevalent cancers worldwide and the second leading cause of cancer deaths among men in Tunisia. Like many cancers, early detection can make a critical difference. With IAEA support, Tunisia is now producing a key radiopharmaceutical used in advanced imaging for prostate cancer, improving access to diagnostic services and reducing reliance on imports. Local production is expected to benefit hundreds of patients across the country and further strengthen Tunisia's nuclear medicine capabilities. atoms.iaea.org/4en3Ez3

How can nuclear techniques help boost food security and the economy? Namibia's seafood sector offers one answer. This #FoodSafetyDay, discover how nuclear science is helping Namibia test seafood faster, meet international standards and protect consumers.

Sustainable agriculture made easier with modelling To keep food safer, food irradiation uses different radiation techniques to keep our food fresh and safe to eat, helping stop food waste. The IAEA, through the Joint FAO/IAEA Centre, has launched a new research project to support countries in using modelling tools to design safer and more efficient irradiation processes, ensuring the safe use of nuclear technologies for food security and safety. ➡️ atoms.iaea.org/4ohvKAD

Nearly twenty years after Ghana’s first imPACT Review mission, an international expert team led by the IAEA has highlighted the country’s strengths and opportunities to expand its cancer care services under the Agency’s #RaysofHope initiative. Assessing all areas of cancer control in Ghana, the review identified where targeted investments could deliver high-impact results, helping strengthen prevention, diagnosis and treatment of cancer. ➡️atoms.iaea.org/4vO3eJq

The IAEA has been informed that, for the 19th time since the beginning of the military conflict, the Zaporizhzhya NPP lost all off-site power at around 21:00 local time last night following an attack on an electrical substation on the other side of the Dnipro River. This latest loss of the Ferosplavna‑1 330 kV back up line comes as the plant prepares repairs on the 750 kV Dniprovska main power line — disconnected since 24 March — under the sixth localized ceasefire agreed with both sides to help restore a second off-site power connection. Operating with only one remaining power line leaves the plant extremely vulnerable to conflict-related grid disruptions as we experience it again today. The ZNPP is currently relying on emergency diesel generators to power the cooling of its six shut-down reactors and maintain other essential nuclear safety functions. The latest loss of off-site power once again highlights the extreme fragility of the electrical grid and the constant dangers to nuclear safety during the war, DG @rafaelmgrossi said, reiterating the urgent need for military restraint to prevent a nuclear accident.
