Nuclear-waste repository in basalt: seal development studies
Current efforts have concentrated on establishing performance requirements and design criteria for a seal system. To accomplish this objective, the repository seal system is considered as one component of the multiple barriers concept of waste isolation. During fiscal year 1982, a simple calculational method to predict steady-state flow rates through a system of shaft seals and backfill zones as a function of plug dimensions, material permeability, and predicted hydraulic gradient has been developed. A Tektronix desk top computer has been programmed to assist in executing the calculations. A preliminary analysis of computer-produced data indicates disturbed rock zone permeability dominates calculated flow rates and travel times and, therefore as further studies proceed, greater emphasis will be given to the disturbed rock zone characterization. As model development continues, many of the assumptions will be removed and fracture flow conditions will be considered. The goal is to develop a model that is supported and verified by design development and laboratory, field, and in situ materials testing. 4 figures.
