Download or read book Summary of Ground Motion Prediction Results for Nevada Test Site Underground Nuclear Explosions Related to the Yucca Mountain Project written by and published by . This book was released on 1996 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes available data on ground motions from underground nuclear explosions recorded on and near the Nevada Test Site, with emphasis on the ground motions recorded at stations on Yucca Mountain, the site of a potential high-level radioactive waste repository. Sandia National Laboratories, through the Weapons Test Seismic Investigations project, collected and analyzed ground motion data from NTS explosions over a 14-year period, from 1977 through 1990. By combining these data with available data from earlier, larger explosions, prediction equations for several ground motion parameters have been developed for the Test Site area for underground nuclear explosion sources. Also presented are available analyses of the relationship between surface and downhole motions and spectra and relevant crustal velocity structure information for Yucca Mountain derived from the explosion data. The data and associated analyses demonstrate that ground motions at Yucca Mountain from nuclear tests have been at levels lower than would be expected from moderate to large earthquakes in the region; thus nuclear explosions, while located relatively close, would not control seismic design criteria for the potential repository.

Download or read book Nonlinear Ground Motion from a Megaton Near Surface Nuclear Explosion written by Norton Rimer and published by . This book was released on 1980 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents finite difference calculations of the ground motions from a one-megaton near-surface nuclear explosion over a saturated soil. These calculations are unique in that they were carried out to a time of 3.26 sec so that the motions could be computed at ranges at which the soil response was linearly elastic. Having a detailed specification of the explosion-induced ground motion on cylindrical monitoring surfaces in the elastic regime, analytical techniques from elasticity will be applied to continue the ground motion through layered earth models out to ranges of 10 to 500 km. The finite difference calculations were initialized at 0.8 msec using results of the Source 3/5 ground coupling calculation which incorporates a detailed model of the nuclear device mass, materials and dimensions. The ground motions were computed out to 5.0 msec in an Eulerian hydrodynamic code and then transferred to the Lagrangian CRAM stress wave code containing appropriate constitutive models, shear failure, tension failure, etc. A bowl-shaped crater was calculated with a cratering efficiency of 37 cu ft/ton of explosive energy, a factor of 5 or 6 smaller than given by empirical scaling formulae based on Pacific nuclear tests.

This book was released on 1984 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of a continuing investigation of the characteristics of the low frequency ground motions produced by atmospheric explosions. The studies reported here have focused on two aspects of this problem: (1) the full-scale validation of nuclear tests, and (2) the preliminary evaluation of a theoretically-based prediction methodology. With regard to the validation study, the mathematical model has been applied to the theoretical simulation of ground motion data recorded from the Nevada Test Site atmospheric nuclear explosions TUMBLER I, UPSHOT-KNOTHOLE 10 and SMALL BOY. The results of these simulations have confirmed the fact that the observed low frequency ground motions from such explosions can be accounted for by the airblast-induced, elastic surface waves. Moreover, the simulation analysis of the ground motion data recorded from the near-surface SMALL BOY explosion has confirmed the existence of an 'exclusion radius' for such events, within which incident airblast energy is not efficiently coupled into the surface wave mode of propagation due to dissipation associated with strong, nonlinear interaction effects. On the other hand, the evidence provided by the TUMBLER I and UPSHOT-KNOTHOLE 10 analyses has indicated that this exclusion radius is effectively zero for explosions with significant height of burst.

This book was released on 1973 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses vertical airblast-induced ground motions produced by nuclear explosions over a dry soil medium taken to model Frenchman Flat of the Nevada Test Site (NTS). Material properties for use in first principle calculations were synthesized from very limited dynamic laboratory stress-strain data, various soil index characteristics, and seismic data. Parametric calculations with a one-dimensional, plane-strain finite difference code were used to define a theoretical simplified model that expresses peak vertical particle velocities and displacements as a function of yield, peak overpressure and depth. Ground motions predicted by this model were then compared to ground motion data from nuclear explosions in Frenchman Flat. In particular, predictions of the simplified model were reasonably consistent with PRISCILLA data which were a primary basis of empirical prediction procedures widely used in the design and analysis of strategic structures during the past ten years. The theoretical model could be altered (where little or no dynamic soil property data exist) to provide even better agreement between calculated and measured ground motions. Conversely, study of qualitative features of the theoretical results provide insight into the basic wave propagation phenomena in Frenchman Flat that could improve the interpretation of the experimental data such that a more consistent comparison between theory and experiment may result.
