Environmental protection is a big issue of NPP technology. Approaches so far have not conducted adequate assessments for severe accidents. Efforts to correct this deficiency are carried out by utilizing the phenomenon of the Fukushima Daiichi NPP accident that has been documented. Relevant aspects were selected to be contributed to the NPP EIA thereby increasing coverage to severe accidents. Content analysis of accident reports and supporting information from international nuclear institutions as well as expert opinion was carried out. The analysis provides results in the form of eight aspects that are suitable to be contributed to the NPP EIA. The correlation between nuclear power generation capacity and environmental radioactive contamination from its accidents and recovery needs is a knowledge challenge that is still being faced. The idea of making the impact of a nuclear power plant accident easy to recover has the potential to be a direction for the development of knowledge and engineering.
