In order to understand the situation of the Fukushima Daiichi Nuclear Power Plant accident that occurred on March 11, 2011, we analyzed the measured values of the amount of released radionuclides that are considered to reflect the core damage state at the time of the accident. The core damage state is estimated based on the analysis results.
