The Next Generation Geothermal Power Plants (NGGPP) study provides the firm estimates - in the public domain - of the cost and performance of U.S. geothermal systems and their main components in the early 1990s. The study was funded by the U.S. Department of Energy Geothermal Research Program, managed for DOE by Evan Hughes of the Electric Power Research Institute, Palo Alto, CA, and conducted by John Brugman and others of the CE Holt Consulting Firm, Pasadena, CA. The printed NGGPP reports contain detailed data on the cost and performance for the flash steam cycles that were characterized, but not for the binary cycles. The nine Tables in this document are the detailed data sheets on cost and performance for the air cooled binary systems that were studied in the NGGPP.

This document provides; a decision analysis summary; problem statement; constraints, requirements, and assumptions; decision criteria; intermediate waste feed staging system options and alternatives generation and screening; intermediate waste feed staging system design concepts; intermediate waste feed staging system alternative evaluation and analysis; and open issues and actions.

Nuclear waste is presently stored in 177 underground storage tanks at -the U. S. Department of Energy`s Hanford Site in Washington State. The storage tanks are of two construction types, 149 single-shell tanks (SSTS) and 28 double-shell tanks (DSTs). No waste has been added to the SSTs since 1980. However, the DSTs are configured to receive additional waste from site waste generators. The overall waste inventory is time dependent and strongly influenced by present and future tank farm operations. These operations include waste evaporation, retrieval, pretreatment, and processing; waste generated from various site facilities; and SST waste inventory transferred to the DSTS. A risk-based simulation model was developed to replicate the waste inventory through the year 2015. The DST waste,,; were divided into three waste types (aging, complexed, @md non-complexed) that were simulated in the model. For each of the three waste types, statistical analyses were performed and the time-de,Pendent waste volumes at the ``mean`` and ``90% confidence level`` were compared with existing DST capacity. Several ``off-normal`` operation scenarios were also analyzed using the risk-based simulation model. Mitigating actions or fallback positions were modeled where off- normal scenarios indicated that capacity shortfalls could potentially occur. The results indicated that selected …

The objective of this effort was to delineate the vertical distribution and concentration of anthropogenic radionuclides in the subsurface surrounding nine boreholes in the 100-N Area available for geophysical logging with the Radionuclide Logging System (RLS). Cesium was defined in eight boreholes, and the ninth hole was found to not contain any such radionuclides.

This report has been developed to support information needs for wastes buried in the Burial Ground Complex. Information discussed is presented in a total of four individual attachments. The general focus of this report is to collect information on estimated source inventories, leaching studies, source control technologies, and to provide information on modeling parameters and associated data deficiencies.

Compilation of monthly reports from departments in the city of San Antonio, Texas providing statistics, project updates, and other information about services and activities. This set of reports includes information about permits for September 1996.
