In-situ tuff Water Migration/Heater Experiment: instrumentation design and fielding
Description
In conjunction with the Nevada Nuclear Waste Storage Investigation Project, Sandia National Laboratories conducted a Water Migration/Heater Experiment in welded tuff at the Nevada Test Site. The heater and associated instrumetation were operated underground for about 7 months during FY80. The instrumentation measured water depth and alkalinity, temperatures, cavity pressures, relative humidity, in-situ stress changes, and displacement in the drill holes and surrounding rock mass. An on-line, calculator-based data acquisition system controlled the experiment and accumulated 120 channels of data. Most instrumentation operated satisfactorily and almost all was recovered for postmortem examination
