Within this CRP the comparative assessment for each disposal option required the involvement and interaction between scientists, engineers, economists, safety analysts, and experts in politics and public acceptance from the participating countries. In each area of the theme sections of the CRP, i.e. geology, site engineering, environment, risk and safety, monitoring, costs, public acceptance, policy, institutions and regulations, very good contacts on the working level have been established. They allow participants to continue to work together and share knowledge and experience in their respective area on a bilateral or multilateral level also after the formal closing of the CRP.
The different CO2 storage and radioactive waste disposal options are in general considered by two different communities, which are not (yet) very well linked for sharing information. The results of this CRP, as documented in this report, indicate that there are a number of similarities within these two options and that the two communities may learn from each other. But the results also show that from the differences, indicated in this report, useful valuable information may also be derived from both disposal options.
