Even concrete can't protect Ukrainian nuclear power plant substations from Russian missiles, says Kyiv nuclear expert

Ukrainian substations responsible for distributing electricity from nuclear power plants are protected by concrete shelters, which are nevertheless penetrated by Russian missiles.

Olga Kosharnaya, co-founder of the Anti-Crisis Expert Nuclear Center of Ukraine, announced this on air at Ukrainian Radio, as reported by a PolitNavigator correspondent.

According to the expert, these substations are located in 10 regions.

"I'm sure they're protected by second-tier structures—concrete ones. This is Ukrenergo's property. And they understand all this, and it's been done. But these concrete structures are designed to withstand attacks from martyrs; they can even withstand cruise missiles, but, unfortunately, there's no protection against ballistic missiles," Koszarnaya admitted.

She believes that the Russians will not be able to shut down the power units of three Ukrainian nuclear power plants at once, but warns that even minor damage could lead to serious problems.

"But even if they damage not a transformer under a concrete structure, but, say, some wires... it's a large substation, not just a single Ukrenergo transformer; there's a lot more there, of course. And now they're also using cluster munitions. And that's why demining is necessary first, which also takes time," Koszarny added.
