ZAPORIZHZHIA, Ukraine (AP) — To be a parent in the Ukrainian front-line city of Zaporizhzhia means weighing your child’s life against the Russian weapons within striking distance.

Most rain death in an instant: the drones, the ballistic missiles, the glide bombs, the artillery shells. But Russian soldiers control another weapon they have never deployed, with the potential to be just as deadly: The nearby Zaporizhzhia nuclear power plant.

The NPP, as it’s known, once produced more electricity than any other nuclear power plant in Europe. It fell to Russian forces in the first weeks of the full-scale invasion, and Russia has held its six reactors ever since. The plant has come under repeated attacks that both sides blame on the other.

These twin dangers — bombs and radiation — shadow families in Zaporizhzhia. Most of the youngest residents of the city have never seen the inside of a classroom. Schools that had suspended in-person classes during the COVID-19 pandemic more than four years ago continued online classes after the war started in February 2022.

So with missiles and bombs still striking daily, Zaporizhzhia is going on a building binge for its future, creating an underground school system.

Construction has begun on a dozen subterranean schools designed to be radiation- and bomb-proof and capable of educating 12,000 students. Then, officials say, they will start on the hospital system.

The daily bombs are a more tangible fear than radiation, said Kateryna Ryzhko, a mother whose children are the third generation in her family to attend School No. 88. The main building, dating to the Soviet era of the children’s grandmother, is immaculate but the classrooms are empty. The underground version is nearly complete, and Ryzhko said she wouldn’t hesitate to send her kids to class there. Nearly four years of online learning have taken their toll on kids and parents alike.

“Even classmates don’t recognize each other,” she said. “It’s the only safe way to have an education and not be on screens.”

Nuclear shadow

Within days of Russia’s full-scale invasion in February 2022, Zaporizhzhia’s 300,000 residents found themselves on the front lines. Unlike larger Ukrainian cities, like Kyiv or Kharkiv, there is no subway system that could do double-duty as a bomb shelter and few schools had basements where students could more safely attend classes.

Many residents left — though some have returned. But the single-family homes and Soviet-style apartment blocks of Zaporizhzhia, the capital of the region that shares its name, filled nearly as quickly with Ukrainians fleeing areas seized by Russian forces, like the cities of Mariupol, Melitopol and Berdyansk.

By the start of the school year in September 2022, which was supposed to mark the post-pandemic return to classrooms, schools were empty. Windows were boarded up to protect against bomb shockwaves, the lawns left unkempt. Fifty kilometers (31 miles) away, the nuclear reactor went into cold shutdown after intense negotiations between the International Atomic Energy Agency and the Russian government.

The IAEA has rotated a handful of staff on site ever since. There are risks even in cold shutdown, when the reactor is operating but not generating power. The main danger is that its external electrical supply, which comes from Ukrainian-controlled territory under constant Russian bombardment, will be cut off for a longer period than generators can handle.

The nuclear plant needs electricity to keep crucial backups functioning, including water pumps that prevent meltdowns, radiation monitors and other essential safety systems.

During a recent Associated Press trip to the Ukrainian-controlled zone closest to the nuclear plant, two airborne bombs struck electrical infrastructure in a matter of minutes as night fell. Russia has repeatedly struck at Ukraine’s grid, attacks that have intensified this year. Highlighting the constant danger, electricity to the NPP was cut yet again for three days as emergency workers struggled to put out the fire. It was at least the seventh time this year that the plant was down to either a single electrical line or generator power, according to the global Nuclear Energy Agency.

“Nuclear power plants are not meant to be disconnected from the grid. It’s not designed for that. It’s also not designed to be operating in cold shutdown for that long,” said Darya Dolzikova, a researcher on nuclear policy at the Royal United Services Institute in London.

Ukrainian President Volodymyr Zelenskyy accuses Russia of targeting nuclear plants deliberately. The 1986 meltdown in Ukraine’s Chornobyl, on the northern border nearly 900 kilometers (550 miles) from Zaporizhzhia, increased the country’s rates of thyroid disease among Ukrainian children far from the accident site and radiation contaminated the immediate surroundings before drifting over much of the Northern Hemisphere. To this day, the area around the plant, known in Russian as Chernobyl, is an “exclusion zone” off-limits except to the technical staff needed to keep the decommissioned site safe.

Russian forces seized control of Chornobyl in the first days of the invasion, only to be driven back by Ukrainian forces.

The Zaporizhzhia plant has a safer, more modern design than Chornobyl and there’s not the same danger of a large-scale meltdown, experts say. But that doesn’t reduce the risk to zero, and Russia will remain a threatening neighbor even after the war ends.

An investment that might seem extreme elsewhere is more understandable in Ukraine, said Sam Lair, a researcher at the Center for Nonproliferation Studies.

“They are there under a conventional air and missile attack from the Russians, and they have experience with the fact that those attacks aren’t being targeted only at military targets,” Lair said. “If I were in their position, I would be building them too.”

In addition, the Zaporizhzhia region received a European Union donation of 5.5 million iodine pills, which help block the thyroid’s absorption of some radiation.

Since the start of the war, Russia has repeatedly alluded to its nuclear weapons stockpile without leveling direct threats. In September, Russian President Vladimir Putin said that Russia would consider any attack by a country supported by a nuclear-armed nation to be a joint attack and stressed that Russia could respond with nuclear weapons to any attack that posed a “critical threat to our sovereignty.”

Ukrainian officials fear that the Russian attacks on Chornobyl and the Zaporizhzhia nuclear plants may be just a start. During his speech in late September to the U.N. General Assembly, Zelenskyy warned that Russia was preparing strikes on more nuclear plants, which generate a large portion of Ukraine’s electricity.

“If, God forbid, Russia causes a nuclear disaster at one of our nuclear power plants, radiation won’t respect state borders,” Zelenskyy said.

Underground for the future

The cost to build a subterranean school system is enormous — the budget for the underground version of Gymnasium No. 71 alone stands at more than 112 million hryvnias ($2.7 million). International donors are covering most of it, and the national and local governments have made it a priority on par with funding the army.

“Everybody understands that fortification and aid for the army, it’s priority No. 1,” said Ivan Fedorov, head of the Zaporizhzhia region. “But if we lose the new generation of our Ukrainians, for whom (do) we fight?”

Daria Oncheva, a 15-year-old student at Gymnasium 71, looks forward to the underground classes, and not just because she’ll finally be in the same place as her schoolmates.

“It’s safer than sitting at home remotely,” she said.

School No. 88, across town, is further along, with rooms carved out and fully lined with concrete thick enough to block an initial onslaught of radiation. The contractor leading the project is also digging trenches for Ukraine’s military. When done, it will also be the primary bomb shelter for the neighborhood, whose single-family homes tend to have small orchards and trellised gardens — but no basements.

An optimistic timeline has the school ready for children by December. It has three layers of rebar totaling 400 tons of metal, plus 3,100 cubic meters of reinforced concrete. The building will be topped by nearly a meter (yard) of earth, concealed by a soccer field and playground.

The school will have an air filtration system, two distinct electrical lines and the ability to operate autonomously for three days, including with extra food and water supplies.

Michael Dillon, a scientist at Lawrence Livermore National Laboratory who studies how people can survive nuclear fallout, said being underground improves survival by a factor of 10.

But Alicia Sanders-Zakre at the International Campaign to Abolish Nuclear Weapons said ultimately people can do more — “which is eliminating these weapons instead of … building, really not even a Band-Aid, for the actual problem.”

Lyudmila Zlatova, who has been the principal at School No. 88 for 30 years, hopes it will be a structure designed for the dangers Zaporizhzhia will face in the future. But she and the parents who gathered on a recent day were most concerned with the present, speaking at the edge of the construction pit as air raid sirens sounded.

It takes 10 seconds for a bomb to reach the neighborhood from the front line, far too short a time to evacuate, and they land with unnerving frequency. The subterranean school’s sunless rooms and concrete corridors will only make children more comfortable, given what they’re already enduring, she said.

“They will feel better studying without windows,” Zlatova said, peering across at the construction site.

Zlatova believes it will bring back at least some of the families who’ve left Zaporizhzhia for other cities in Ukraine or elsewhere in Europe. The city remains fully functional, with public transit operating and grocery stores, markets and restaurants operating, and repairs ongoing for structures damaged by shelling — albeit in limited fashion. Around 150 of the school’s 650 prewar students have left the city, but she said she’s in touch with absent families and many promise to return home once there is a safe place to study.

Gymnasium No. 6, which runs from first grade through high school, already has one. Its main building sits on the city’s easternmost edge, closer than any other school to the front 40 kilometers (25 miles) away.

Little wonder that its principal, Kostyantyn Lypskyi, seems a little frayed at the beginning of the academic year. But at least his students can attend because parents chipped in money last year to renovate the basement shelter about 50 meters from the main school building into a series of classrooms.

His underground school, whose concrete walls and relatively thin metal doors are not radiation proof but protect against explosions, hold around 500 people — the same number as the new designs. The school has double that number, so students will alternate weeks. The youngest children study full-time just upstairs from the shelter, and the older ones are in the main building.

“Of course it will work,” he said. “We prepared everything for the start of the new school year.”

In the earliest days of the school year, an air raid alarm meant he could test that confidence. It took five minutes from the moment the sirens sounded until the last children took their seats and spread out their books, awaiting instruction.

It was morning, and they were ready for the day ahead.
