Why does the reactor in the fukushima daichis nuclear plant have to be cooled to prevent another catastrophe?

Vidette

... in Japan? Is the atomic reactor manufacturing more performance than it be compelled? Does temperature influence the production in the know about nuclear energy? Is the nuclear mill at the risk on to exploding?(Just a note to say I'm willy-nilly being unsympathetic to the tragedy that unhappily Japan is facing in this very difficult spell. On the snappish. I'm trying grate on nerves conceive it better. I'm benevolent grate on nerves the Japanese people plus I aspiration they vanquish this as soon as possible).

first of all...all those reactors were attempted to being placed on shut down mode, that means many things1) No more electricity is being produced until the reactors and the radioactive isotopes within them can be controlled2) The temperature must be controlled also, it must be kept under 35 deg Celsius to minimize producing unwanted radioactive ions in the cooling water. 3) The water within the reactor is suppose to have a minimum height from the top of the cores to the top of the water of 200 inches. (When that 35 deg Celsius reaches 80 to 100 deg Celsius, this is the point when simmering and boiling off of the cooling water takes place AND when all the water is boiled off into steam, then the core becomes exposed. Then temperatures really start to rise as in FUKUSHIMA Reactor 3 which exploded and the top of the roof fell into the exposed core, which now makes it more difficult to get water on top of it. Radiation levels are much too high to get close to it so the Japanese govt and TEPCO are trying to get tons of Boric acid on top of it.) All their measures are almost too late. The top of building 3 has 250 times the lethal radiation dosage allowed to humans and 100 times within a dozen meters of it. They have a few chances left: they need to get that Boric acid in there to help absorb all the neutrons that are flying around out of control. The whole area should be placed off limits to humans for the next 50000 years. This is double the half life of Plu ton ium 239 which is one of the many isotopes that the reactor cores contain. Last thing they should do is pour 1 million tons of concrete over all the reactors. Then the people in Tokyo may have a chance at low cancer rates.
