In a serious accident,a neclear plant's reactor vessal cracks,and all of the cooling water drains out.Although nuclear fission stops,readioactive decay continues to heat the reactor's 2.5 x 10^5 kg uranium core at a rate of 120 Mega-Watts.Once the core reaches its melting point,how much energy will it takes to melt the core? How long will the melting take?
