Japan Earthquake: nuclear plants - Page 429

Lets just get the facts straight, using this data that 200GJ of energy is required for a melt through we can then calculate using the formulas provided that the time for melt through is using Po=1380MW
0 minutes after shut down - 4hours
01 hours after shut down - 5 hours
02 days after shut down - 11 hours
30 days after shut down - 26 hours
60 days after shut down - 36 hours

It's pointed out that that is time for fuel melt rather than melt of core through the bottom

I would go with water level is one metre below where the bottom of the rods would have been had there been any rods left, then.

Nuclear fuel at Fukushima No. 1 unit melted after full exposure | Kyodo News

Tokyo Electric Power Co., the operator of the crippled Fukushima Daiichi nuclear power plant, revealed Thursday that holes had been created by melted nuclear fuel at the bottom of the No. 1 reactor's pressure vessel.
The company said it has found multiple holes adding up to several centimeters in welded piping. Earlier in the day, it said the amount of water inside the troubled reactor was unexpectedly low -- not enough to cover the nuclear fuel -- hinting that a large part of the fuel melted after being fully exposed.

So it was, after all, the meltdown that pierced the pressure vessel?
