A direct impact could result in an excessively high release of radioactivity
Na terça-feira, o diretor-geral da Agência Internacional de Energia Atômica, Rafael Grossi, levou ao Conselho de Segurança da ONU um alerta que ressoa além das fronteiras do Oriente Médio: a central nuclear de Barakah, nos Emirados Árabes Unidos, foi atingida por um drone originário do Iraque, e a humanidade esteve mais perto do que imagina de uma catástrofe radiológica de proporções históricas. O incidente não é apenas uma crise de segurança regional — é um lembrete de que a infraestrutura nuclear civil, construída sobre promessas de progresso, carrega em seu interior a possibilidade de um desastre que não respeita fronteiras nem soberanias. A crise imediata foi contida, mas a vulnerabilidade permanece exposta, como uma ferida que o alívio temporário não fecha.
- Um drone atingiu a central nuclear de Barakah no domingo, incendiando um gerador e colocando em risco os sistemas de resfriamento de reatores ativos carregados com toneladas de material nuclear.
- Grossi alertou o Conselho de Segurança da ONU que um impacto direto no reator poderia liberar radioatividade em um raio de centenas de quilômetros, exigindo evacuações em massa numa região já devastada por conflitos.
- O drone foi rastreado até o Iraque, onde grupos militantes apoiados pelo Irã conduzem uma campanha sistemática de ataques contra países vizinhos, sinalizando que Barakah não foi um alvo acidental.
- A energia foi restaurada e os sistemas de backup funcionaram, evitando o pior — mas a margem entre o incidente contido e o desastre regional dependeu inteiramente da redundância técnica, não da dissuasão política.
- O episódio expõe uma lacuna crítica: instalações nucleares civis em zonas de conflito ativo permanecem vulneráveis a ataques com drones de baixo custo e alta precisão destrutiva.
Rafael Grossi, chefe da Agência Internacional de Energia Atômica, apresentou-se ao Conselho de Segurança da ONU na terça-feira com um aviso que poucos queriam ouvir: a central nuclear de Barakah, nos Emirados Árabes Unidos, havia sido atacada por um drone no domingo, e as consequências poderiam ter sido catastróficas. O drone atingiu um gerador que abastecia a instalação na região de al-Dhafra, deflagrando um incêndio. Barakah não é um projeto em papel — é uma usina em operação, com toneladas de material nuclear ativo e irradiado em seus reatores.
Grossi foi preciso ao descrever os riscos. Um impacto direto no reator poderia liberar níveis perigosos de radioatividade. Mas há um risco ainda mais silencioso: se os sistemas de energia fossem cortados, o resfriamento dos reatores falharia, podendo provocar um colapso do núcleo. Um acidente dessa magnitude no Oriente Médio exigiria evacuações em massa, distribuição de iodeto de potássio e abrigo para populações em um raio de centenas de quilômetros — numa região já marcada por conflito e instabilidade.
Os Emirados identificaram rapidamente a origem do drone: o Iraque, de onde grupos militantes apoiados pelo Irã têm lançado ataques contra países vizinhos desde o início da guerra no Golfo. O ataque a Barakah não foi isolado, mas parte de uma escalada regional que agora mira infraestrutura nuclear.
A energia foi restabelecida. Os sistemas de backup funcionaram. A crise imediata passou. Mas o alerta de Grossi não era sobre o que aconteceu — era sobre o que pode acontecer na próxima vez que os sistemas redundantes não forem suficientes.
Rafael Grossi, the head of the International Atomic Energy Agency, stood before the United Nations Security Council on Tuesday with a stark warning: a nuclear power plant in the United Arab Emirates had just been attacked, and the consequences could be catastrophic. The target was the Barakah nuclear facility, located in the al-Dhafra region in the western part of the country. A drone had struck the plant on Sunday, igniting a fire in a generator that supplied electricity to the installation. Now, Grossi was spelling out what that meant.
The Barakah plant is not a theoretical concern or a facility in planning stages. It is operational, running right now, which means it contains thousands of kilograms of nuclear material inside its reactor cores—both fresh fuel and spent fuel that has already been irradiated. A direct hit on the reactor itself could release dangerous levels of radioactivity into the environment. But there is another, perhaps more insidious risk: if an attack disabled the power lines feeding the plant, the cooling systems could fail. Without cooling, the reactor cores could melt. And a meltdown at Barakah would not be a localized disaster. Depending on wind patterns and other factors, the radioactive release could affect an area spanning anywhere from several kilometers to several hundred kilometers in radius.
Grossi was careful to lay out the full spectrum of what that would mean. In the worst case, governments would need to evacuate populations across that entire zone. People would need to shelter in place. Potassium iodide would need to be distributed to protect thyroid function. The scale of such an operation—in the Middle East, in a region already fractured by conflict—would be unprecedented in the nuclear age. "I want to be absolutely clear," Grossi said. "In case of an attack on the Barakah Nuclear Power Plant, a direct impact could result in an excessively high release of radioactivity to the environment."
The question of who fired the drone was answered quickly. The UAE announced that the unmanned aircraft had originated in Iraq, where Iranian-backed militant groups have been conducting a campaign of strikes against neighboring countries since the war in the Gulf began. The attack on Barakah was not an isolated incident but part of a broader pattern of regional escalation, with nuclear infrastructure now squarely in the crosshairs.
What happened next offered a measure of relief, though not reassurance. The IAEA confirmed that power had been restored to the Barakah facility. The generator that had caught fire was not the only source of electricity to the plant; backup systems existed and had functioned. The immediate crisis had been averted. But the incident had exposed something uncomfortable: a major nuclear power plant in a volatile region had been successfully targeted by a drone, and the only thing standing between a contained incident and a potential regional catastrophe was the existence of redundant systems. Grossi's warning was not about what had happened. It was about what could happen next time.

Why does a successful attack on a power generator matter so much if the plant has backup systems?
Because the backups work—this time. But Barakah has four reactor units. If a drone took out both the primary and backup power supplies simultaneously, or if it hit the reactors directly, there is no backup for cooling. The plant would have minutes to prevent a meltdown.
And if that happened?
Radioactivity spreads with the wind. Grossi was saying that in the worst case, you're evacuating hundreds of thousands of people across a region that's already dealing with war. You're distributing iodine tablets. You're sheltering populations. It's not a contained industrial accident.
Who is doing this, exactly?
Iranian-backed groups in Iraq. They've been escalating attacks on Gulf states since the war started. This is the first time they've hit nuclear infrastructure. It suggests either a new capability or a new willingness to take that risk.
Why would they target a nuclear plant? What's the strategic gain?
That's the question no one wants to answer directly. Either it was a mistake—they hit what they thought was a military target. Or it was deliberate, to demonstrate that nothing is off-limits. Either way, it works as a message.
And the UAE? What are they doing?
They restored power, they're investigating, they're talking to the IAEA. But they can't make the plant invulnerable to drones. That's the real problem Grossi was pointing to.
