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.

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.
