INVESTIGATION ON THE SPECIES OF Np AND Pu IN GROUNDWATER AND ENGINEERED MATERIALS BALANCED WATER BY CALCULATION

The species of Np and Pu under the geological disposal conditions are studied by the calculation method. Using the geochemistry model EQ3/6, the species of Np and Pu in groundwater, engineered barriers balanced water are investigated. Input parameters including all the environment factors such as temperature, pH, Eh and CO 2 concentration, are studied to show the effects on the species. The calculated results provide useful information for the lab work.
