AbstractAbstract
[en] TEPCO (Tokyo Electric Power Company Holdings) and NDF (Nuclear Damage Compensation and Decommission Facilitation Corporation) plan to start mass-extraction of nuclear fuel debris from the Fukushima Daiichi 1st, 2nd and 3rd plants in 2021. Several methods for quantitative nuclear material analysis of debris are investigated and considered. For the purpose, we have proposed to perform dual energy X-ray CT (Computed Tomography) and neutron resonance absorption by portable 950 keV/3.95 MeV X-band (9.3 GHz) electron linac X-ray/neutron sources. Proof-of-Principle experiments are under way. Updated achievement is presented. (author)
