IAEA: Gunfire, drone attack at Ukraine’s Zaporizhzhia nuclear plant
The International Atomic Energy Agency team at Ukraine’s Zaporizhzhia nuclear power plant (ZNPP) reported hearing gunfire near the site this morning while a drone hit the plant’s training center.
In a news release today, IAEA director general Rafael Mariano Grossi said this is the third drone to target the training center, located just outside the site perimeter, so far this year. He called for an immediate end to drones being flown over or near nuclear facilities.

An interpretative model is proposed for a series of percolation tests conducted on glauconitic sand columns. Colloidal 241Am leached from a simulated vitrified waste was used as the migrating radioisotope. The polydispersed nature of the 241 Am colloids was demonstrated, together with a sorption saturation mechanism, which was interpreted with a Langmuir isotherm. The model equations include convection, filtration, and sorption of the polydispersed colloid in solution. Good agreement was found between model and experimental results.
