those control rods (scram system) had done their work.
as a nature of nuclear reactor, the power won't go zero as it 'shutdown',
decay heat from fission products still generate a faily large amout of heat,
say, around 6.5% of its orginal normal power at the moment of reactor
shutdown, 0.4% one day later. Think of thermal power of a typical reactor is
around 1000~3000MW, decay heat is A LOT.
Now the key is to cool the core from decay heat to prevent its melt... 阅读全帖 |
