2006 annual report of No.8 sub-group (evaluation and modeling of geochemical mechanisms for long-term dissolution and alteration of waste glass) in the prioritized cooperative research program

This is the 2006 annual report of No.8 sub-group (evaluation and modeling of geochemical mechanisms for long-term dissolution and alteration of waste glass) in the Prioritized Cooperative Research Program (PCRP). Target of the study in this sub-group is improving reliability of radionuclide release from the waste glass as source of long-term behavior. And then elucidating geochemical mechanisms of the waste glass, and making long-term dissolution model are scheduled. In the fiscal year of 2006, the PCRP meeting was held two times. Previous data on dissolution of waste glasses and the recent research results were discussed in these meeting. Documents and the minutes are shown in this report. (author)
