Abstract	During the FY 1998 Saltcake Dissolution Workshop, participants identified nine tasks to be performed prior to the FY 1999 workshop. Discussions during the workshop indicated that significant progress was made in each area. The workshop focused on the strengths and weaknesses of the Environmental Simulation Program (ESP). In addition, the ESP predictions for the Tank SY-101 remediation and the ESP validation efforts were evaluated. Finally, the need for a broader user base was identified. At the request of the Tank Waste Remediation System (TWRS), the ESP model was successfully utilized to predict the effects of Hanford tank farm operations such as waste transfers and water dilutions. The ESP model was originally developed to predict the compositions of solutions from off gas scrubbers. Therefore, the original database for the ESP model was designed for use with solutions with low ionic strengths. However, the Hanford tanks contain waste with very high ionic strengths. TWRS and Tank Focus Area (TFA) staff members have measured the solubilities of key components at high ionic strengths. The results from these studies were used to develop the Hanford database for the ESP model so the model could more accurately predict the compositions of Hanford waste streams with high ionic streams. The OLI Corporation, which developed the ESP model, has now incorporated most of the Hanford database into its standard ESP database. Another deficiency of the ESP model involves the lack of detailed documentation. Most new users of the ESP model normally encounter several obstacles. Therefore, TWRS management has proposed the development of an ESP user guide based on the experiences of TWRS and TFA researchers. The objective of the user guide is to make the ESP model more user friendly for the Hanford process engineers.
