Generally speaking, a vast, advanced and unfamiliar science and technology which has the potential hazard, is unacceptable by public for the fear of its unknown nature. The siting problem of geological disposal for high level radioactive wastes is one of the typical examples.
There is only one disposal concept in Japan now. However, there might be a lot of choices because it can be promoted greater understanding by comparative study. This study examined the point that installed appropriate choices to explain in specialists in another field etc. other than the nuclear backend field.
At first, this study surveyed the part where recognition and understanding of the safety when disposing of high level radioactive wastes (HLW) were not able to be shared by the discussion between specialists before. As a result, it has been understood that it is the evaluation etc. part which are "Disposal scenario and safety evaluation result" and "Forecast of a technology concerned in the future".
Therefore, it seems as the position and the region of the evaluation etc. good to install these choices. Moreover, the form of choices seems to be good two or more disposal concepts that cost and safety are evaluated on one candidate site. In addition, it seems that these choices are used and it is good for "Specialists other than the nuclear power back end to which the range in the field made a specialty has adjusted" at the academic society etc. to repeat the explanation and the discussion.
