Due to the Great East Japan Earthquake that occurred on March 11, 2011, Fukushima Daiichi Nuclear Power Station Units 1 to 3 were considered to have experienced a severe accident accompanying core melting. Analytical work to grasp the situation of the accident is carried out simultaneously with the waste furnace work. We independently tried to estimate the state of core damage by analyzing the measurement values of radionuclides after the accident.
