This paper statistically analyzes residents’ understanding of problems related to radioactively contaminated water discharged from nuclear power and nuclear reprocessing plants. Moreover, this paper examines their impact on the surrounding fisheries by using the cases of La Hague, Sellafield, and Fukushima Daiichi Nuclear Power Plant. Survey data shows that more than 60% respondents disagree with the release of contaminated water, and this sentiment is particularly strong among both British and French respondents. Regarding seafood caught in the vicinity of the nuclear power and nuclear reprocessing plants, although British respondents noted that they hold it in high regard, many people do not purchase this seafood. In contrast, many Japanese respondents reported that they were less concerned, and thus, willingly purchase seafood caught off the coast of Fukushima Prefecture. In all three countries, many people did not trust government information on the release of contaminated water. Compensation to the affected people was provided by the central government, companies involved, and local governments, in that order. Japanese and British respondents reported higher expectation for compensation as compared to French respondents. Japanese and French respondents noted that they have knowledge of radioactive materials and contaminated water, and many of them purchased seafood caught in the vicinity of the nuclear power and reprocessing plants. British respondents were the most opposed to the release of contaminated water, whereas Japanese respondents were the least reliant on government information about the release of contaminated water. Finally, among those who trusted information from the government and retailers, French respondents were the least concerned about contamination. French respondents were also the least likely to expect any compensation for the fishermen affected by contamination. Both British and French residents around the affected plants expected the central government to compensate the affected fishermen, whereas those who did not reside around the affected plants did not expect the fishermen to be compensated. French respondents were more likely to expect compensation from the local governments; affluent respondents were more likely to expect the compensation to be funded by taxation, whereas less affluent respondents expected them to be funded by donations. Respondents who were more skeptical of government information wanted the companies involved to compensate the fishermen. British respondents reported a tendency for wanting the companies involved to provide this compensation, and did not support the concept of compensation provided through donations.
