Instead of pumps, valves and human operators, the plant USES airflow, pressure changes and gravity to gradually cool the reactor.

这家电站没有使用管道、阀门和人工操作，而使用了气流、压力变化和重力来逐步冷却反应堆。

When one row on one side blows air at a higher pressure than the other it causes the airflow over the trailing edge on that side to bend up or down, in exactly the way that an aileron would, and the plane rolls accordingly.
