How much cooling do those reactors need if the fuel rods were OK and the control rods are fully inserted? More than passive water cooling with whatever flow can be achieved through convection? Are these MOX fuel rods hotter than regular uranium? Because if they can't keep the place flooded with water, it sounds like they are going to need to pump out the (underground?) electrical room and hope they can get circulating pumps working again. I can imagine the electricians drawing straws who has to do that job. :( In a couple of hours the sun comes up on another day there.=20 It sounds like a tough scramble.
