Reactor4 had one explosion and 2 fires in March 2011

Tepco published the in-house Fukushima accident investigation report on 6/20/2012.

In this report, which is assumed to downplay the accident, Tepco reported that there were 2 fires in reactor4 after the explosion, and those fires were naturally extinguished fortunately.

Also, it is stated that they could not approach SFP4 because the radiation level was too high.

Tepco is emphasizing the safety of SFP4 to say they can inject cooling water even when another aftershock hits Fukushima, but it suggests they won’t be able to reach SFP4 in case of another accident. (cf, Tepco has no clue for the worst senario of SFP4)
