PLC power control system, having been developed, simulated the transient process of the core decay power from 8% full power to 2% full power while blackout accident.

开发PLC功率调节系统，模拟了全厂断电事故工况下堆芯衰变功率从堆芯8%额定功率到堆芯2%额定功率的变化过程；

RTGs power many space missions — including NASA's Cassini and New Horizons probes — as the slow decay of small pellets of radioactive material produces heat that can be turned into electricity.

RTG已为许多太空任务提供动力，包括美国宇航局的“卡西尼号”和“新视野”探测器。在放射性物质的小球衰退过程中可以产生出热量，从而将其转化为电能。

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）。

If the cooling system were to lose power during the initial decay period of 24 to 48 hours, a meltdown would likely follow.

The tsunami destroyed the diesel generators that provide power to drive the pumps that circulate the water coolant through the reactor that removes decay heat.

If the offcuts weren't fed into power stations, they would be burned as waste or left on the ground to decay, producing methane and CO2.
