The control rods are also used to shut the reactor down from 100% power to about 7% power (residual or decay heat).
它也用来关闭反应器，可以从100%的动力降到7%动力（残留的延迟的热量造成）。

The persistent heat nurtured buoyant demand for residual fuel oil and direct crude burning for power generation, as electricity consumption soared to meet air conditioning demand in the region.
