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.

Two methods for spectral shift control have been proposed for pressurized water reactors. The first method is a mechanical spectral shift where the moderator-to-fuel volume is changed. The second method is a chemical one in which the D2O/H2O ratio is changed. Utilization of a combination of the two methods has been suggested and analyzed. It was found that the advantage of the combined method is better than the sum of the advantages of the two methods separately. Emphasis was on using the spectral shift controls for one-batch reloads in order to increase the fuel cycle’s length and thus the electricity production. It was found that it is possible to increase electricity production during the plant’s lifetime by ∼6 to 9% compared to three and four batches using a regular control.
