The backups can only do so much. If you take 5\6 off line to cool 3\4, the 5\6 overheats.

I looked up the old posts from last week. The gen-sets were knocked out, but the reactors were in cold shutdown for maintenance so they didn't need the additional cooling.

The gen-sets were knocked out, but the reactors were in cold shutdown for maintenance so they didn't need the additional cooling.

After the quake, the control rods dropped and ALL the units were in "cold shutdown." However, cooling must continue as heat is still generated by the deterioration of the remaining byproducts of the reaction. Hence, all reactors (except 4, which had no fuel rods in the reactor), and all the spent fuel pools need continuous cooling.

Reactors 4, 5 and 5 were down for maintainence but the fuel pools needed to be kept cool. 5 and 6 still had the gensets so no big deal. 4 did not so now it is one of the problem children.
