Well, see the link in that message, apparently pour water
as they were doing. -g- There was certainly
some melt if there was hydrogen explosion, likely
significant melt. -ng- But... we printed over it. HOHOHO!

Message 27245816

For the boil-off rate of 60 gallons per minute a week after
shut down, it takes around 200 seconds for the water level
inside the reactor pressure vessel to drop an inch. If the
reactor cooling system fails one week after the reactor was
shut down with the water level inside the reactor vessel is
at its normal level, it would take approximately 11 hours for
boil-off to reduce the water level down to the top of the
reactor core.

Without cooling, the boil-off would continue to drop the
water level below the top of the nuclear fuel in the reactor
core. As nuclear fuel was uncovered by water, it would begin
heating up. As the fuel temperature increased to 1,800°F, a
chemical reaction between the metal cladding of the fuel rods
and the steam flowing past would generate large quantities of
hydrogen. If the heat-up continued past 2,200°F, the exposed
fuel would begin to melt.
