Five walls against risk communication of nuclear technology

The author has made efforts to establish risk communication in the nuclear industry since the JCO criticality accident. Some people understood the importance and the usefulness of risk communication both for local residents and their own business. Others, however, thought it troublesome, costly, and useless for their organization and nuclear safety. I think, unfortunately, experiences after the Fukushima accident force them to hesitate at communicating risks with the public more and more. I will discuss why and how risk communication of nuclear technology is difficult. (author)
