Information base for waste repository design. Volume 3. Waste/rock interactions

Abstract

This report is Volume 3 of a seven volume document on nuclear waste repository design issues. A portion of the work reported in this document was performed by Colder Associates, Inc., under a subcontract to TASC.

Permeameter studies of water flow through cement and clay borehole seals in granite, basalt and tuff

“…Regulatory Commission a seven volume.document on nuclear waste repository design issues entitled "Information Base for Waste Repository Design". Volume 1 of this document, by Koplik et al (1979) concerns borehole and shaft sealing. The main conclusions regarding borehole sealing were as follows:…”

“…The technique of sealing by compaction of natural earth Two other points are worth noting in this report. First, regarding seal failures, Koplik et al (1979) indicate that the most common cause of seal failure during emplacement is by contamination and/or transport of the seal material by ground water. Failure to achieve seal effectiveness usually results from underestimating the difficulties of emplacement.…”
