For decommissioning and contaminated water countermeasures in Fukushima Daiichi NPS, we identify locations and mounts of fuel debris in RPV using muon technologies, and it is intended to contribute to the selection of an efficient fuel removal methods. Therefore we conducted muon measurement using Attenuation Method at Unit-1, and we confirmed that Muon measurement for the investigation of damaged reactor is promising technology. And the measurement results at Unit-1 suggested the non-existence of fuel...
