The decay heat drops off very slowly after about 1 day where the decaypower is already below 2% of the operating power of the reactor.
在核反应产生的热量降至平时的2%后的第一天,衰变热就降低得很缓慢乐。

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