Fukushima Daiichi Unit 3 melt-through
May 24, 2011, TEPCO admitted (core melt) melt down from past February after the accident.
I was investigated melt down melt-through of Unit 3.
TEPCO, does not expose the data of 3/11 19:30 previously for water level and pressure of the reactor.
Further, it does not expose the data in the 3/19 06:30 previously also temperature data.
Therefore, no choice but to guess situation immediately after the accident.
I , report of October [National Institute of JNES '22 (BWR) Heisei analysis of 2009 year earthquake level 2PSA] from data,
I think the accident of Unit 3 to choose the case closest to the accident of Unit 3 of this time.
Adopted the [accident progress analysis of 2.3 BWR-4 Mark Ⅰ type reactor facility] Since the BWR-4 Mark Ⅰ The Unit 3.
Power loss assumption at this time is (TBU).
The analysis result, the fuel falls, try reactor pressure vessel damaged in about 3.6 hours, it is overtemperature damage containment about 6.9 hours to about 1.7 hours.
