Dissolution experiments were performed on actual samples of NWCF Run H-4 radioactive calcine in fiscal years 1998 and 1999. Run H-4 is an aluminum/sodium blend calcine. Typical dissolution data indicates that between 90-95 wt% of H-4 calcine can be dissolved using 1gram of calcine per 10 mLs of 5-8M nitric acid at boiling temperature. Two liquid raffinate solutions composed of a WM-188/aluminum nitrate blend and a WM-185/aluminum nitrate blend were converted into calcine at the NWCF. Calcine made from each blend was collected and transferred to RAL for dissolution studies. The WM-188/aluminum nitrate blend calcine was dissolved with resultant solutions used as feed material for separation treatment experimentation. The WM-185/aluminum nitrate blend calcine dissolution testing was performed to determine compositional analyses of the dissolved solution and generate UDS for solid/liquid separation experiments. Analytical fusion techniques were then used to determine compositions of the solid calcine and UDS from dissolution. The results from each of these analyses were used to calculate elemental material balances around the dissolution process, validating the experimental data. This report contains all experimental data from dissolution experiments performed using both calcine blends.

This report provides information on the timing of submission of the mid-session review for FY1980-FY2009, a 30-year period that covers all or part of the administrations of five Presidents, applying to the last two years of the Carter Administration, and the full terms of the Reagan, George H. W. Bush, Clinton, and George W. Bush Administrations.

This report shows in tabular form how much the Administration requested and how much Congress appropriated during the past 11 years for U.S. payments to the multilateral development banks (MDBs). It also provides a brief description of the MDBs and the ways they fund their operations. It will be updated periodically. Three companion reports provide further information on the MDBs. See CRS Report RS20793, Multilateral Development Banks: Basic Background, CRS Report RS20791, Multilateral Development Banks: Procedures for U.S. Participation, and CRS Report RS22134 International Financial Institutions: Funding U.S. Participation.
