Since the FUKUSHIMA-DAIICHI Nuclear Power Plant accident, a significant issue to develop human resources for nuclear and radiation technology has been growing up. A strong effort will be made, based on the serious experiences of troubles/accidents, to restore social confidence by developing engineers having high sense of ethics beyond logic of organization.

Japan Atomic Energy Agency has performed risk communication at Horonobe Underground Research Center, using the Public Information House and Underground Research Laboratory (URL), to promote understanding R&D of geological disposal technology and waste disposal against public. In this paper, we conducted the analysis of questionnaire investigation performing after visiting those facilities from FY2013 to FY2017. The results show that long-term safety would gain prominent attention as agita factor by growing understanding. The results also shows that visiting to those facility would become valuable experience to understand geological disposal because, for example, respondents with visiting to URL positively evaluated necessity, appropriates and safety of geological disposal, compared with those without visiting URL.

In the 2016 fiscal year, communication cases on general waste disposal facility construction plans in recent years were surveyed. Results suggested as follows: (1) Existing long-term relationships or agreements in local area promote local accepting. (2) An operator needs to consider alternative plans and explain reasons for the decision making to local stakeholders. (3) Even after first announcement of a new plan, an operator needs to review the plan depending on local concerns. (4) Announcement of a new plan will activate communications on local development including the site redevelopment.

JAEA Ningyo-toge Environmental Engineering Center and Fukushima Environmental Safety Center have same challenges in risk communication. As reference, similar domestic cases were investigated by our two Centers, and requirements for building long-term relationship were clarified. As follows; (1) Develop new relationship with various stakeholders in the region. (2) Make better use of existing resources (personnel, land and facilities, etc.). (3) Make a concerted effort to create new values with local stakeholders. (4) Make an opportunity which local stakeholders confirm safety and build confidence to the project. These efforts will enhance the opportunities for operators and residents to learn about environment management and environmental protection.

At the request of the government of Japan and Fukushima prefecture, the Nuclear Fuel Cycle Engineering Laboratories and the Nuclear Science Research Institute of the Japan Atomic Energy Agency (JAEA) conducted the internal dosimetry examination program for the residents of Fukushima prefecture (Fukushima residents) affected by the Tokyo Electric Power Company (TEPCO) Fukushima Daiichi Nuclear Power Plant accident by whole-body counting (WBC) starting in July 2011, the year of Great East Japan Earthquake and Tsunami. At the internal dosimetry examination, almost Fukushima residents worried about effects of radiation and suffered from various serious situations, which were caused by not only the nuclear accident but also the earthquake and tsunami. Therefore, JAEA had direct dialogue focused on active listening, as risk communication with Fukushima residents in order to mitigate Fukushima residents' anxiety and stress. This report evaluates the effects of the activities and shows the ways of our communication with Fukushima residents during WBC to mitigate Fukushima residents' anxiety and stress.

Nuclear Fuel Cycle Engineering Laboratories (NCL) of JAEA has held the explanatory meetings in Ibaraki prefecture since May 2011 in order to transmit factual information and reduce the excessive anxiety about radiation risk. Applying to our past risk communication process to the explanatory meetings, we built a process of interactivity between participants and our staff for the meetings. We incorporated the participants' needs into the meetings, and, as far as possible, we had interactive two-way communication so that the meetings were not one-way and persuasive but promote mutual understanding. According to the opinions and the results of questionnaire survey that were received from the participants, it became evident that the interactive explanatory meetings were effective in reducing participants' anxiety. This report explains the risk communication process for carrying out the explanatory meeting, and shows the activities of the meetings, questions and opinions from the participants, and questionnaire results that NCL implemented.

JAEA has held public meetings on radiation and its health effects mainly for parents of students in kindergartens, elementary schools, and junior high schools in Fukushima prefecture after the Fukushima nuclear accident. These meetings are held based on our experience of practicing risk communication activities for a decade in JAEA with local residents. Questionnaires were collected after the meetings. By analyzing questionnaires, we confirmed that interactive communication is effective in increasing participants' understanding and in decreasing their anxiety. Risk communication study office supported the staff members of the meetings providing information such as participants' questions in the past meetings. To provide information, we made a homepage and held the orientation for the staff members Questionnaires of the staff members were also collected and analyzed after the public meetings.

We had been conducting a research on risk perception and confidence-building among stakeholders regarding environmental remediation of Uranium mine site and disposal of industrial waste from FY 2007. FY 2011, we study how the Great East Japan Earthquake and Fukushima nuclear accident affects public risk perception. Therefore, a questionnaire survey on public risk perception of environmental remediation of Uranium mine site and disposal of the industrial waste in Okayama prefecture had been carried out. Another questionnaire survey on public risk perception of the disposal of disaster waste for residents in Okayama prefecture has been carried out. Following are some of the results: (1) For risk perception regarding environmental remediation of Uranium mine site, "knowledge of radiation" and "Concern about radioactive material" and "Information literacy" did not change significantly. Conversely trust in "Public administration" and "facility owner" and "Science and technology" was decreased significantly. (2) For risk perception regarding disaster waste, many people recognize the need for wide area disposal of disaster waste. Conversely, many residents are concerned about radioactive materials.

Times Cited Count：14 Percentile：71.01(Public, Environmental & Occupational Health)The Fukushima Daiichi accident raises a fundamental question: Can science and technology prevent the inevitability of serious accidents, especially those with low probabilities and high consequences? This question reminds us of a longstanding challenge with the trans-sciences, originally addressed by Alvin Weinberg well before the Three Mile Island and Chernobyl accidents. This paper, revisiting Weinberg's issue, aims at gaining insights from the accident with a special emphasis on the socio-technical or human behavioral aspects lying behind the accident's causes. In particular, an innovative method for managing the challenge is explored referring to behavioral science approaches for a decision-making process on risk management; such as managing human behavioral risks with information asymmetry, seeking a rational consensus with communicative action, and pursuing procedural rationality through interactions with the outer environment. In short, this paper describes the emerging needs for Japan to transform its national safety management institutions so that these might be based on interactive communication with parties inside and outside Japan.

This paper presents a study on knowledge dependency of plant operator behavior. The ultimate purpose of this study is to establish a methodology to support human operators in forming an integral understanding (i.e., mental model) of target plants, and thus to enhance potential performance in unexpected situations and in non routine cognitive tasks. The authors conducted a series of experiments to acquire behavioral data of two plant anomalies not included in the training curriculum. A formulation methodology of operator protocols has been proposed from the observations of the acquired behavioral data. It has been concluded that engaged plant operators have sufficient knowledge about physical phenomena of the major components, and that possible improvements of operators' cognitive performance can be expected mainly by knowledge enhancement about utilization strategy of physical information.

Even if good relationship with stakeholders is build once, there is a possibility that the relationship is lost over time. And this might be risk of long-term management. Therefore, it is important to prevent the relationship is gradually lost. Information sharing with consideration on changing needs of stakeholders or changing values in society is required.
