2 Software Program to Ascertain Radionuclides Residual Concentration (SPARRC) Rajiv Khera,P.E. *** Radionuclides Web Cast Meeting August 4, 2004

3 2 Overview Background Capabilities Demonstration Next Steps

4 3 Background SPARRC (Software Program to Ascertain Radionuclides Residual Concentration) mass balance model estimates uranium and radium concentration and volume of in waste streams and finished water appropriate for pre-design decision making 1992 SAB Panel recommendations guided approach

5 4 Capabilities Current Visual Basic ® application has 6 treatment technologies TechnologyContaminants Coagulation FiltrationUranium/(Arsenic) Lime SofteningUranium/Radium Ion ExchangeUranium/Radium/(Barium) Reverse OsmosisUranium/Radium/(TDS) Activated AluminaUranium/(Arsenic) Greensand FiltrationRadium/(Barium)

6 5 Capabilities Predictive, decision-making tool Regional and State personnel Utility operators Comparisons across technologies Quantity and quality of wastes Radionuclide removal efficiency Comparisons across operating parameters Treatment optimization Waste treatment or disposal planning

7 6 Lime Softening Demonstration

8 7 Next Steps External peer review Incorporate review comments and user data SPARRC available at: Users can upload field input and output data Actual plant data help improve the precision and accuracy of SPARRC
