  • 1. Japan Nuclear Energy Safety Organization, Tokyo (Japan)

Description

In order to contribute to an improvement of accident managements and station blackout countermeasures for NPSs in Japan after the accident of Fukushima Dai-ichi Nuclear Power Stations (NPSs), Japan Nuclear Energy Safety Organization (JNES) has analyzed the progress of the accident scenarios and situation of reactor of the unit 1, 2 and 3 of Fukushima Dai-ichi NPS based on the information such as fragmentary plant chronologies, parameters and information disclosed by TEPCO and tried to figure out the rational explanation of behavior of each plant. In addition, JNES has compared and categorized the event sequences by using event tree method based on the event progression of Fukushima Dai-ichi, Fukushima Dai-ni, Tokai Dai-ni and Onagawa NPSs in order to extract important events and key factors from the viewpoint of prevention of core damage events and impact to event progression.
