Keywords:Fukushima Daiichi nuclear power station, decommissioning, fuel debris retrieval, dose rate distribution, Monte Carlo calculation

The three-dimensional dose rate distribution at the end of 2021 in the primary containment vessel of the Fukushima Daiichi nuclear power station was predicted by combining various numerical calculations such as Monte Carlo calculation and measured data obtained in the internal investigations.
