This is true, in particular, for the relationship between tectonics and the ground-water flow system which, of course, is a key player in the .

    Geologic characterization of Yucca Mountain and its surroundings has taken more than 2 decades of investigations carried out by the U.S. Geological Survey, the national laboratories, and numerous academic and consulting groups. The object of this work—to quantify the environmental hazards that might attend a proposed high-level nuclear waste repository at Yucca Mountain—has produced a body.

Get this from a library. Three-dimensional thermal analysis of a high-level waste repository. [T J Altenbach; United States. Department of Energy.; U.S. Nuclear Regulatory Commission.]. A three-dimensional thermal analysis using finite difference techniques was performed to determine the near-field response of a baseline spent fuel repository in a deep geologic salt medium.

A baseline design incorporates previous thermal modeling experience and OWI recommendations for areal thermal. The cooling response of a single ventilated storage room in an unventilated array of rooms is examined.

Calculations show that ventilation provides a thermal sink in the heated system inducing temperature gradients in the formation different from the unventilated case. An asymptotic cool-down limit. The engineering design of disposal of the high level waste (HLW) packages in a geologic repository requires a thermal analysis to forecast the temperature history of the packages.

Calculated temperatures are used to demonstrate compliance with criteria for waste acceptance into the geologic disposal gallery system and as input to assess the Cited by: 2.

Introduction. Three principal repository designs that have been identified for the disposal of high level radioactive waste (HLW) in geological formation are in-floor disposal, in-room disposal (EUR, ; EUR EN/FR, ) and disposal in very deep drill holes (Ringwood,Ringwood, ).The “in-floor” type disposal concept comprises the construction of a tunnel network Cited by: T.

Altenbach has written: 'Three-dimensional thermal analysis of a high-level waste repository' -- subject(s): Thermal analysis, Radioactive waste disposal in the ground. This is followed by a coupled thermal-hydrologic-mechanical analysis to evaluate the impact of nuclear waste repository in porous water containing rock mass.

This analysis has been under taken in accordance with the Indian reference disposal system. The paper considers the changes in pore pressure and stresses due to excavation of disposal by: For the mechanical stability assessment of a deep underground high-level waste repository.

computer simulations using FLAC3D were carried out and important parameters including stress ratio, depth.

Worldwide, there has been a long-standing scientific consensus that the best method for permanent disposal of high-level radioactive waste is in deep geologic repositories (e.g., see National Academy of Sciences, National Research Council report,and Nuclear Energy Agency report, ).There are many analogues that support this conclusion, e.g., ore deposits that have existed for.

The FRACON code was used in the preliminary analysis of the coupled T-M-H response of a sparsely fractured rock mass around a hypothetical nuclear fuel waste repository.

It was found that the flow and structural characteristics of this rock mass could be significantly Cited by: 3. Spent nuclear fuel and high-level radioactive waste can be disposed in deep horizontal drillholes in sedimentary, metamorphic or igneous rocks.

Horizontal drillhole disposal has safety, operational and economic benefits: the repository is deep in the brine-saturated zone far below aquifers in a reducing environment of formations that can be shown to have been isolated from the surface for Cited by: 1.

Environmental Monitoring and Adaptive Staging Essential steps in an Adaptively Staged geologic repository program are: (1) monitoring the repository environment, including its component engineered barriers as well as its natural barriers; (2) scientific and programmatic evaluation of the new data, and (3) using this data in decisions to move.

The analysis was performed using the ANSYS finite- element analysis code. The waste package is modeled as a three-dimensional solid. The seismic loads were applied as acceleration loads at supports. After the model was constructed, a modal solution was obtained to find the natural frequencies and mode shapes of the geometry.

The post-closure performance of a generic horizontal drillhole repository for the disposal of spent nuclear fuel (SNF) is quantitatively evaluated using a physics-based numerical model that accounts for coupled thermal-hydrological flow and radionuclide transport processes.
