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

Riyana, E. S.; Okumura, Keisuke; Terashima, Kenichi

Determination of fuel debris location and distribution inside primary containment vessel of Fukushima Daiichi Nuclear Power Station is important to decide further decommissioning step and strategy. We calculate neutron flux produced from fuel debris and secondary particles photon resulted from neutron reaction with nuclides inside fuel debris, including direct photon emission from FPs in fuel debris. Neutron and gamma characteristics resulted from calculation could be use as basis for determination suitable spectrometer system or detector for searching, localizing and treatment of fuel debris.
