In a serious accident, a nuclear power plant's reactor vessel cracks, and all of the cooling water drains out. Although nuclear fission stops, radioactive decay continues to heat the reactor's 2.5 X 105 kg uranium core at a rate of 120 Mega-Watts. Once the core reaches its melting point, how much energy will it take to melt the core? How long will the melting take? The melting point is 1406 k and the boiling point is 4091 k.

Top Answer

Latent heat of fusion for uranium is 50 KJ/kg So Heat required to melt the entire core = 2.5*10^5 *... View the full answer
