Calculation of gamma and neutron emission characteristics emitted from fuel debris of Fukushima Daiichi Nuclear Power Station

ABSTRACT Determination of fuel debris location and distribution inside the primary containment vessel of Fukushima Daiichi Nuclear Power Station is important to decide further decommissioning step and strategy. We calculate neutron and photon spectra including the contribution of secondary particles in the primary containment vessel of Fukushima Daiichi Nuclear Power Station. The Calculated Neutron and photon spectra can be used as the base for determination suitable spectrometer system or detector for searching, localizing and treatment of fuel debris.
