The solubility of Zr, Nb and Ni in groundwater and concrete water, and sorption on crushed rock and cement

Abstract

The Finnish power companies, Teollisuuden Voima Oy (TVO) and Imatran Voima Oy (IVO) intend to dispose of decommissioning and operating wastes in repositories at the power plant sites, Olkiluoto and Haestholmen. The Olkiluoto repository is fully operational for operating wastes and the Haestholmen repository is under excavation. This study examines the solubilities and sorption of three activation product metals, zirconium, niobium and nickel. The solubilities were investigated by oversaturation method in NaOH solutions of Different pH and in TVO groundwater and by undersaturation method in TVO and IVO groundwaters and concrete waters. The solution concentrations in the undersaturation studies were 2x10{sup -9} mol/l, 2x10{sup -9} mol/l and about 1x10{sup -7} mol/l for zirconium, niobium and nickel, respectively. The sorption of the metals was studied for crushed rock/groundwater systems, for crushed rock/concrete water systems (tonalite and TVO waters; rapakivi granite and IVO waters) and for crushed cement/concrete water (TVO and IVO) systems. The K{sub d} values of zirconium were 0.19-0.36 m{sup 3}/kg in the tonalite/TVO groundwater system and 0.53-1.88 m{sup 3}/kg in the cement/TVO concrete water system. For niobium the K{sub d} values were 0.04-0.17 m{sup 3}/kg for tonalite/TVO groundwater, 0.07-0.60 m{sup 3}/kg for cement/TVO concrete water, 0.09-0.58 m{sup 3}/kg for  More>>
