Horonobe Underground Research Center managed by Japan Atomic Energy Agency (JAEA) is the Japan's best environment to understand the project of geological disposal of high-level radioactive waste, because there is an Underground Research Laboratory (URL) in the center besides an exhibition facility which explains the content of research conducted in the URL. In the area of the center, there is also an exhibition facility for the full-scale model of engineered barrier system of geological disposal. JAEA takes advantage of this opportunity to conduct public hearing including questionnaire research regarding the questions, anxieties and comments by the visitors for geological disposal project. This report summarizes the result of statistical analysis of 3,349 visitors from April 2018 to January 2019.

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.

The Horonobe Underground Research Center conducts research and development to enhance the reliability of geological disposal technology, indicate the margin of technical safety for legally decided depth of repository, improve understanding of the deep geological environment, and promote greater public understanding for geological disposal technology. "YUME chisoukan" ceased its role as an exhibition facility as of end August 2012 as part of an administrative reform under the then Democratic Party rule, and came to be focused on disclosing the underground drifts to ascertain that JAEA is true to its tripartite agreement signed between the Hokkaido Prefecture, Town of Horonobe and JAEA (i.e., no nuclear materials will be used, etc.). It is also used as the facility to provide information on the research results of the Center. This report presents the statistical results of a questionnaire (2,566 responses) conducted from April to October 2013.

This report summarizes the review work to paraphrase nuclear technical terms with clear and brief explanations. Explanation with nuclear technical terms was not very acceptable to the public in a variety of contexts. The objective of this study is to paraphrase from the public point of view. JAEA has conducted a survey on public attitudes toward fifty-nine nuclear technical terms by using an online questionnaire. Most of them were frequently used in the brochures of JAEA. The survey clarified the public awareness and comprehension of each term. Thirty-two terms, which was subject to paraphrase on a priority basis, were selected from fifty-nine nuclear technical terms based on our importance rating. At the work to paraphrase thirty-two terms, emphasis was placed more on clearness and briefness than on scientific accuracy. They are reviewed through focus group interviews. This study brought results on recognizable style and thirty-two well-polished paraphrases.

Recently, an imaging plate (IP) was developed. Pu analysis by an IP was studied in the JAEA Cooperative Research Scheme on the Nuclear Fuel Cycle, and the availability about detection of Pu and discrimination with radon progenies was shown. In order to apply these results to the radiation control, this research aims at evaluation of radioactivity, discrimination with radon progenies, and evaluation of AMAD by an IP. In the conventional autoradiography (ARG) by a ZnS and Polaroid film, Contamination of Pu can only be grasped by viewing. Since the digital data of the radiation and location is obtained by an IP, Pu can be detected quantitatively and radioactivity can be evaluated. As a result of this research, the image of alpha emitter on an IP is the same as that of the conventional ARG, and can be applied also to the ARG of beta and emitter. In measurement of Pu, the function of Image J (image-analysis software) was very available. Pu radioactivity was evaluated by an IP.

This research aims to gain an understanding of local socio-environmental characteristics surrounding the Ningyo-Toge Environmental Engineering Center, from the viewpoint of bidirectional information sharing. In order to clarify the relevant issues, we analyzed publicly available information over the past 20 years. We also conducted an internet survey to assess risk perceptions etc. and feelings toward local enterprises, of residents in the surrounding localities and the general public. Expectations for economic benefits of the facilities began to fade in mid 1980s while negative aspects drew increasing attention. Local assemblies disputed over reliability, not technical safety. In Okayama prefecture there found a strong sense of avoidance toward radioactive waste disposal, the background of their refusal of carrying-in of waste rock from Togo-cho, Shimane prefecture. A majority of local residents see nuclear facilities as highly dangerous. National newspapers, NHK, professional researchers were identified as reliable sources of information regarding atomic energy and radioactivity, indicating the effectiveness of information dissemination through them. Though residents in the surrounding localities are aware of economic benefits of nuclear facilities, a majority of them would refuse the siting of a new one. Meanwhile, revitalization of local communities was found to be in need, in which local enterprises were expected to participate.
