Calculation of Quad-Cities Central Bundle Documented by the U.S. in FY98 Using Russian Computer Codes (open access)

Calculation of Quad-Cities Central Bundle Documented by the U.S. in FY98 Using Russian Computer Codes

The report presents calculation results of isotopic composition of irradiated fuel performed for the Quad Cities-1 reactor bundle with UO{sub 2} and MOX fuel. The MCU-REA code was used for calculations. The code is developed in Kurchatov Institute, Russia. The MCU-REA results are compared with the experimental data and HELIOS code results.

Experimental Results of NWCF Run H4 Calcine Dissolution Studies Performed in FY-98 and -99 (open access)

Experimental Results of NWCF Run H4 Calcine Dissolution Studies Performed in FY-98 and -99

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.

A/M Area DNAPL Characterization Report for Cores Collected in FY97 and 1Q98 and 2Q98 (open access)

A/M Area DNAPL Characterization Report for Cores Collected in FY97 and 1Q98 and 2Q98

Drilling activities were conducted in FY97 and FY98 in the A/M Area to further identify areas of pure phase DNAPL below the water table. The purpose of the work was to further understand the subsurface contaminant distribution and to identify locations below the water table where aggressive DNAPL remediation technologies should be pursued.

Texas Environmental Enforcement Task Force: Report to the Task Force Member Agencies (open access)

Texas Environmental Enforcement Task Force: Report to the Task Force Member Agencies

Report summarizing the work of the Texas Environmental Enforcement Task Force for fiscal years 1991-2001. It provides an overview of the task force organization and activities, general progress, and supporting statistical data. The report also discusses specific programs -- Environmental Crime Prevention Week in Texas, and training for law enforcement allies to prevent pollution -- and discusses new challenges for the group.
