| Outline of Final Research Achievements |
In the disposal facility of high-level radioactive waste, bentonite blocks will be used as artificial barriers. It is necessary to use a lot of pieces of bentonite block to fill up the disposal pit. A bentonite block is very low hydraulic conductivity, however, water migration of contact part between bentonite blocks is a cause for concern. To solve this concern, this study has researched the possibility on binding of compacted bentonite blocks by electromagnetic wave raying and water putting through laboratory experiments. From the experimental results, the conditions of possible bonding has be clarified.
