概要
An accident scenario of Fukushima Daiichi Nuclear Power Plant, Unit 3 is analyzed from the data open to the public. The author assumed that the high pressure coola nt injection system stopped before TEPCO stopped it manually, and the vapor in the reactor pressure vessel is condensed in the condensate storage tank. The estimat ion describes that the rupture time of the reactor pressure vessel was at 8:55 13/3/2011. The estimation shows that the rupture time of the pressure containment ves sel was at 9:05 13/3/2011. These estimations are different from the ones by TEPCO, however; many measured evidences show good accordance with the present scenario.
