[2I04] Estimation of plant condition of Fukushima Daiichi Nuclear Power Station
(1) Analysis of measured values of released radionuclide into atmosphere
Keywords:Fukushima Daiichi Nuclear Power Station, severe accident, FP behavior, analysis of radioactivity, estimation of plant condition
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.
