This letter report describes the technical activities of the waste element solubility study during Fiscal Year (FY88, October 1, 1987 to September 30, 1988). This experimental waste element solubility study provides experimentally determined limits on radionuclide concentrations in groundwater from Yucca Mountain. Furthermore, the results of this study are essential for verifying the validity of radionuclide transport calculations, and for providing the maximum concentrations for the radionuclide sorption tests. Solubility is the source term for radionuclide transport calculations. The solubility in this study is controlled by fewer variables than are used in the multiparameter transport model. Therefore, modeling must be capable of predicting the results of this waste element solubility study. Agreement between the experimental result and the modeling predictions will validate the geochemical module of the transport model. 3 refs., 8 figs.

The U.S. Interagency Geothermal Coordinating Council was a multi-agency group charged with identifying and reducing barriers to geothermal energy development in the U.S. Many of the issues covered related to regulations for and progress in the leasing of Federal lands in the West for power development. The IGCC reports are important sources of historical information. (DJE 2005)
