A Consideration on Nuclear Data Needs for 1F Decommissioning
After 8 years from the accident at TEPCO Fukushima Daiichi Nucleat Power Station (1F), the "on-site" R&D situation has been changed into new phase. It can be considered like from understanding to predicting by many direct and indirect measurements and analyses. In this presentation, nuclear data needs for 1F decommishioning are revisited according to these situation. The needs for accident evolution characteristcs, criticality management, deburis strage, waste management, etc. are considered with the view point of R&D on prediction what is going on and will be happened in each stage of decommisioning.
