High science and technology lead to the large gap between experts and non-experts in the level of understanding or the decision making about acceptability regarding the science and technology. We took up a high-level radioactive waste (HLW) as one of high science and technology, developed the communication field on the web for public outreach regarding a HLW, and carried out the second test operation of the communication field in 2005. In this paper, we analyzed the results of the second test operation from the viewpoints of information flow both from experts to citizens and from citizens to experts. In consequence, we found that this field is effective as a information supplement field, but is not sufficient as a interactive communication field between experts and citizens.
