Both the ICS and PCCS heat exchangers are submerged in a pool of water large enough to provide 72 hours of reactor decay heat removal capability.
22.
This is known as decay heat and is the major safety driver behind the cooling of nuclear reactors, because this decay heat must be removed.

24.
The thermal dynamics and inertia of the entire system of the core-unit in its containment silo is sufficient to absorb and disperse decay heat.
25.
These engines are able to provide emergency electrical power for reactor decay heat removal, as well as enough electric power to supply an emergency propulsion mechanism.
26.
The removal of the decay heat is a significant reactor safety concern, especially shortly after normal shutdown or following a loss-of-coolant accident.
27.
The reactors and storage pools are being cooled now and decay heat in the reactors that were running at the time of the accidents is almost entirely gone.
28.
The large mass of liquid metal also acts as a heatsink capable of absorbing the decay heat from the core, even if the normal cooling systems would fail.
29.
The remaining reactors were shut down / SCRAMed automatically after the earthquake, and the remaining decay heat of the fuel was being cooled with power from emergency generators.
30.
The oxide layer produces heat primarily by decay heat, while the principal heat source in the metal layer is exothermic reaction with the water released from the concrete.
