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.

Risk communication at Horonobe Underground Research Center, using the Public Information House and Underground Research Laboratory

Osawa, Hideaki; Nogami, Toshinobu; Hoshino, Masato; Tokunaga, Hiroaki*; Horikoshi, Hidehiko*

Genshiryoku Bakkuendo Kenkyu (CD-ROM), 26(1), p.45 - 55, 2019/06

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 paper describes an analysis of the opinion survey that is carried out at the internal dosimetry using whole body counters conducted in Japan Atomic Energy Agency. JAEA staffs explained the examination results of WBC to the residents in private booths and provide necessary advice for them. We carried out two opinion surveys at the internal dosimetry. The first survey was carried out before the screening in order to realize the residents' views of the accidents; the second survey was carried out after the personal dialogue in order to receive the evaluation from examinee for our correspondence. The first survey showed that residents' anxiety about radioactive exposure, hereditary influence on next generation, and so on. On the other hand, more than 90% residents answered in the second survey that "uneasiness reduced" as a result of the direct dialogue. Our private dialogue has also considerably effects.

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.

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.

Japan Atomic Energy Agency has been carrying out internal dosimetry for Fukushima residents by trust of Fukushima prefecture from July 2011. To perform result explanation on the inspection day is the merit of investigation at JAEA. As a result of analysis of the awareness of the examinee, anxiety about radiation exposure tended to be considerably reduced after inspection. The importance of the interactive communication was demonstrated.
