How well protected are Ukraine’s nuclear power plants?

DW, Lilia Rzheutska, 1 Nov 23

Ukrainian air defense systems recently downed Russian attack drones near the Khmelnitsky nuclear power plant. But falling debris still damaged the site. Are power plants in danger?

On the night of October 25, Ukrainian authorities reported downing Russian Shahed kamikaze drones near the Khmelnitsky nuclear power plant, in the country’s west. Falling debris and a wave of detonations caused significant damage to the town of Netishyn, where power plant employees live. The nearby town of Slavuta was also affected. Some buildings belonging to the nuclear facility itself were also damaged. Ukrainian President Volodymyr Zelenskyy said the drones were likely sent to attack the power plant. 

Experts from the International Atomic Energy Agency (IAEA) who are at the nuclear plant confirmed two loud explosions had occurred near the plant. They were later informed that two drones had been shot down at a distance of five and 20 kilometers, respectively.

AEA director General Rafael Grossi later stated on the organization’s website that powerful explosions near the power plant that night had temporarily cut off power to two radiation monitoring stations. According to Grossi, the detonations did not, however, disrupt the plant’s operations, nor did they affect the power grid. The explosion did, meanwhile, shatter several windows at the plant. “This incident again underlines the extremely precarious nuclear safety situation in Ukraine, which will continue as long as this tragic war goes on,” Grossi said. “The fact that numerous windows at the site were destroyed shows just how close it was. Next time, we may not be so fortunate.”

……………………………… A nuclear power plant is more than just a reactor, says Dmytro Humenyuk, who heads the safety and analysis unit of Ukraine’s scientific and technical center on nuclear and radiation safety. It is a complex facility that consists of safety systems that provides electricity for the plant itself, and transports power generated by the plant. Falling debris or shelling powerlines and substations could lead to a power outage at the nuclear power plant and trigger a dangerous situation, Humenjuk says.

High-voltage substations, through which electricity produced at the nuclear power plant is fed into the power grid and without which the facility cannot function safely, must be well protected from missile and drone attacks well as falling debris. “When substations come under fire, the nuclear power plant’s emergency protection is activated,” says nuclear energy expert Olha Kozharna. “Such an emergency stop is very dangerous for the power plants.”……………………………………………………………  https://www.dw.com/en/how-well-protected-are-ukraines-nuclear-power-plants/a-67271615 #nuclear #antinuclear #nuclearfree #NoNukes
