Which outcome occurs when a nuclear power plant's cooling system fails, during radioactive decay?

💡 Explanation

If decay heat exceeds cooling capacity, fuel assembly temperatures rapidly increase causing zircaloy cladding to react via Metal-Water Reaction. This forms zirconium oxide and hydrogen which can accelerate the runaway, therefore fuel element cladding reaches eutectic temperature, rather than control or shielding mechanisms limiting the damage.
