Sensors and Monitoring to Assess Grout and Vault Behavior for Performance Assessments

Abstract
To support performance assessment (PA) of waste vaults and grout monoliths, the National Institute of Standards and Technology (NIST) has performed a preliminary evaluation of the state-of-the-art of sensors, nondestructive evaluation methods, and any relevant geophysical techniques that may be used to quantify changes to the intended chemical (e.g. redox state) and structural properties (e.g. crack initiation, development and propagation) of large engineered waste isolation systems. If the vaults and monoliths remain intact, the system performance should be consistent with the successful performance anticipated from the PA. Events such as cracking, however, could lead to significant changes in the overall vault or monolith performance. Measurement techniques that could be used to detect the onset of cracks and to detect changes in the chemical are summarized in the context of a monitoring program.Citation
