The dose rate around the surface of retrieved fuel debris is important information for radiation shielding, handling, transport, analysis and storage of the fuel debris. Therefore, we have developed a dose rate prediction method applicable to various fuel debris to be sampled from the Fukushima Daiichi Nuclear Power Station in the near future. Using the method, we predicted the dose rate of the fuel debris to be sampled in 2021 and clarified the sensitivities to the contributing parameters.
