Keywords:Fukushima Daiichi Nuclear Power Station, Dose Rate Distribution, ORIGEN2, Decay Library, Photon Library

Decay and photon data libraries for ORIGEN2 calculation were developed for burnup calculation and dose rate distribution based on JENDL Decay Data Library (JENDL/DDF-2015). The validity of the libraries was confirmed by comparing the calculated results with measured decay heat and photon spectral data.
