The plant's operators responded incorrectly to the situation and stopped cooling the reactor, which overheated, suffered damage, and released radioactive material inside the plant.

核电站的操作人员对情势反应不当，停止对反应堆进行冷却，导致反应堆过热而破损，并将放射性材料释放到核电站内。

Update: There's no evidence of any radioactive leakage, but officials have confirmed that the cooling process for the nuclear plant has not yet gone according to plan.

更新：现在还无法证明有辐射泄漏，但官方已经确认核电站的冷却程序没有按照设定的工作。
