A15-2 Available energy

The mass of the molten core is about 110 t (61 t of UO2, 18.8 t of Zr, 29.2 t of stainless steel). The initial temperature of the corium ranges between 2000K and 2500K and the final temperature, after quenching in water, is about 400K. 

On the basis of the specific heat and of the fusion heat, the specific thermal energy is about 1 MJ kg and therefore the total energy amounts to about 110000 MJ.
