I recently saw National Geographic's movie special called "Aftermath: Population
Zero" where they showed how the world will become if all humans suddenly disappeared.
Part of the movie they talked about how there are these radioactive rods which
can heat to 1000+ ^c if left uncooled, so if energy is gone then the cooling mechanism
fails, leaving the super heating rods to heat and explode, resulting in a massive
explosion per power plant(I think they said something like 500 times bigger
explosion than Hiroshima and Nagasaki's).
Question is - Can't they just link up the energy that these hot rods produce to the
cooling mechanisms.. it'll take some time before the machinery fails... better then nothing, eh?
Another solution is digging a deep hole which the hot rods will fall into in case of
major problem, this way the demage will be MUCH less severe..
Hell, why won't they move the power plants underground and live risk free(for us, not them)??
