Abstract

  In this paper, we focus on the kind of information the nuclear industry should provide for the general public to understand and trust in the plan of plutonium utilization for mixed-oxide fuel in light water reactors, i.e., Pu thermal utilization. We conducted an interview survey for 30 people who live in the Tokyo metropolitan area to analyze what they know and how they feel about Pu thermal utilization, and to compare three information materials based on their subjective evaluation of the degree of understanding, trust and so on. The content analysis of interviewees' comments regarding Pu thermal utilization shows that they have vague but correct knowledge, that is, “Pu thermal utilization is to recycle nuclear fuel or nuclear waste.” However, people do not have background information concerning the necessity of Pu utilization, such as the resource limitation of uranium. According to the comparative analysis of the three materials, a material that presents the necessity and usefulness of Pu thermal utilization using figures and graphs was evaluated most understandable, informative, trustful, and persuasive. The material including information of risk was evaluated more informative, but the evaluation of trust indicated a divided opinion. People who feel anxiety about nuclear power generation evaluated the material including risk messages more trustful than other materials. Others evaluated it less trustful because the risk management of Pu thermal utilization and the process to solve remaining problems, such as HLW disposal, are uncertain.<br>
