Concrete Chemical Evolution

Description: The objectives of this analysis are to discuss and evaluate testing results that were performed for the M&O by the Pennsylvania State University (PSU) to evaluate the potential long-term evolution of organic admixtures in cementitious materials at elevated temperatures. The testing was designed to help provide a basis for a determination by the Performance Assessment group (PA) of the long-term acceptability and longevity of cementitious materials for repository use. The main purpose of the… more

Behavior of temperature and concentration of shallow groundwater in the Raft River Geothermal Area

Description: A moderate-temperature (140/sup 0/C) geothermal power plant demonstration, sponsored by the Department of Energy, is currently under development in South Central Idaho. Environmental concerns about the quality of the local shallow groundwater prompted a modeling study. Simulation results (1) suggest significant thermal and quality levels within the 30-year projected plant operation and (2) makes obvious the importance of understanding the interconnected hydraulic systems.
