Abstract:
The Grout Disposal Program at Hanford, Washington, will dispose of low-level radioactive mixed wastes as a grout in near-surface disposal vaults. The radioactivity makes direct physical measurement of the quality of the grouted waste difficult. This article describes the development of pulse-velocity testing methods for verification of grout quality and the evaluation of three test methods: ultrasonic pulse velocity, crosshole sonic logging, and mechanical crosshole seismic tests.
