Part of: Dynamic Analysis and Design Considerations for High-Level Nuclear Waste Repositories


This paper discusses categories of instruments that are available and recommended for consideration to monitor the engineering performance and interactions of the geologic media, groundwater, and the structural facilities in a high-level waste repository. Instrumented performance monitoring is a means of verifying design assumptions for both the construction, or pre-closure phase, as well as the sealed, or post-closure phase after construction. The seismic response of the media and the constructed facilities is an important consideration in planning the instrumentation. Surface and sub-surface facilities are discussed, and settlement, pore water pressures, soil/rock pressures and displacements, structural stress/strain, and temperature monitoring needs are described.
