Solubilities of neptunium and plutonium were studied in J-13 groundwater (ionic strength of about 3.7 mmol; total dissolved carbonate of 2.8 mmol) from the proposed Yucca Mountain Nuclear Waste Repository site, Nevada, at three different temperatures (25, 60, and 90 °C) and pH values (6.0, 7.0, and 8.5). Experiments were performed from both over- and undersaturation at defined CO2 partial pressures. The solubility of 237Np from oversaturation ranged from a high of (9.40 ± 1.22) × 10-4 M at pH 6…

The partitioning of uranium and neptunium onto hydrothermally altered concrete
Partition coefficients (Kd) of U(VI) and Np(V) on untreated and hydrothermally altered concrete were measured in 0.01 M NaCl and 0.01 M NaHCO3 solutions as functions of concentration of the
