This paper describes the root causes of the catastrophe that resulted from the failure to protect Fukushima Daiichi Nuclear Power Plant under combined impact of March 11, 2011, M= 9.0 Tohoku Earthquake and the powerful tsunami that followed. The root causes are examined from the PRA (Probabilistic Risk Assessment) point of view specifically focusing on the event tree analysis used in fundamental design decision making for construction of Fukushima Daiichi Nuclear Power Plant reactors.
