... Project Salt Vault (Bradshaw, 1971) isolation of nuclear waste in mined openings in rocksalt has been rigorously investigated. To eliminate the possibility of radio-nuclide escape to the biosphere, a primary requirement of the design of an underground repository must be the long term stability...

..., and by overcoring tests at shallow depths in the same general area. The measured stresses were used in an assessment of the stability of large reactor caverns for housing the nuclear components of a proposed 4 × 850 MWe underground nuclear power plant in Precambrian hard rock. It was found that under ambient...

... stability for alternative magnet designs and proposed rock sites in Wisconsin for a prototype magnet present unique engineering problems requiring comprehensive field, laboratory and numerical studies. Analysis of three promising magnet designs and five possible rock units (granite, quartzite, rhyolite, two...

... Compressed air energy storage in salt caverns induces low-frequency cyclic loading effects in rock salt. An ongoing study is described which will furnish data for assessing associated stability of storage caverns. Some initial findings are presented from laboratory and in-situ mine tests...

... The suitability of the old and operating mines in Finland for the storage and final disposal of the different kinds of nuclear wastes was analysed. Due to several unfavorable factors related to either the design or stability of the free spaces, the geological conditions, or the environmental...

... In some designs, the rock at the face of an unlined storage cavity may be stressed beyond its maximum strength, and the article presents how an analytical model can be used to describe the conditions of failure in the rock and their effects on stability. It is henceforth possible to use...

... led to examine with particular care the problems of cavity stability and well tightness. Brine reinjection into a cavity has confirmed the predictions and legitimized the approach adopted. INTRODUCTION For over 10 years now, Gaz de France has been storing natural gas in underground cavities...

... better space for future installations or it might offer better prospects for long-term stability of the rock surrounding the excavation. Restrictions to the proposed blasting to avoid damage or disturbances should be clarified already at the planning stage, too. If this is done before bidding takes place...

... measurements are considered in assessing design of rock cavern support systems, cavern liner requirements, and rock cavern stability under both thermal and seismic loads. The overall safety of the underground station design is also discussed. In this context the predictions of a preliminary analysis...
