This book was released on 1985-02-01 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the earth's population would survive the immediate horrors of a nuclear holocaust, but what long-term climatological changes would affect their ability to secure food and shelter? This sobering book considers the effects of fine dust from ground-level detonations, of smoke from widespread fires, and of chemicals released into the atmosphere. The authors use mathematical models of atmospheric processes and data from natural situationsâ€"e.g., volcanic eruptions and arctic hazeâ€"to draw their conclusions. This is the most detailed and comprehensive probe of the scientific evidence published to date.

This book was released on 2005-10-06 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underground facilities are used extensively by many nations to conceal and protect strategic military functions and weapons' stockpiles. Because of their depth and hardened status, however, many of these strategic hard and deeply buried targets could only be put at risk by conventional or nuclear earth penetrating weapons (EPW). Recently, an engineering feasibility study, the robust nuclear earth penetrator program, was started by DOE and DOD to determine if a more effective EPW could be designed using major components of existing nuclear weapons. This activity has created some controversy about, among other things, the level of collateral damage that would ensue if such a weapon were used. To help clarify this issue, the Congress, in P.L. 107-314, directed the Secretary of Defense to request from the NRC a study of the anticipated health and environmental effects of nuclear earth-penetrators and other weapons and the effect of both conventional and nuclear weapons against the storage of biological and chemical weapons. This report provides the results of those analyses. Based on detailed numerical calculations, the report presents a series of findings comparing the effectiveness and expected collateral damage of nuclear EPW and surface nuclear weapons under a variety of conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The approximate physical distribution and condition of displaced and ruptured rock materials in the Rainier and Neptune areas were established by geologic observation of structural and lithologic details, and stratigraphic correlations. The effects of the detonations were found to be related to the rock types considered from the standpoint of engineering materials as well as to their structural positioning. Gross displacements and fracturing are in apparent accord with Mohr theory of rupture stress orientation. Factual data find explanation on the fundamental basis of primary (blast) and secondary (gravity) induced principal stresses. The 90 plus or minus 20-ton Neptune explosion disaggregated and displaced rock materials to a radial distance which ranged between 45 and 100 feet from ground zero depending on the orientation of bedding plane weaknesses and proximity of the ground surface to the point of detonation. Primary fracturing extended from ground zero to a radial distance which ranged from 55 feet to an estimated 145 feet depending on the favorable distribution of geologic structural weaknesses. Neptune was found to exhibit primary (blast) and secondary (gravity) rupture features which are fundamentally the same as those found in thc Rainier area. The 1700-ton Rainier shot initiallyformed a fused- rock-lined cavity of an average 62 plus or minus 10foot radius below ground zero and an undetermined radius above ground zero Gross primary rock displacement and gain disaggregation took place to a radiul distance of from 80 to 130 feet from ground zero. Visible primary fracturing extended to a radial distance which ranges between 150 and 220 feet depending on the proximity of hard brittle rock (welded tuff) which, it is concluded, transmitted rupture stresses to a much greater distance than the "punky" granular tuff. Collapse of rock material into the initial cavity was favored by primary shear fractures, which developed prominently to a radius of 150 feet from ground zero. The collapsed rock defines a 100-foot-diameter cylindrical zone. This zone is presumed to extend for 388 feet upward from ground zero. A dome-shaped top is postulated on the basis of Mohr stress theory. It should be noted that, with the exception of drill hole G, there has been no drilling or underground working above the Raise'' Drift. Cavities, distributed around the perimeter of the cylinder, are attributed to variations in the coherence of the rock strata which were disrupted during collapse. The collapse block has remained essentially intact. This fact, coupled with the virtual absence of radioactive fission products above ground zero and nearly complete pulverization of the central collapse block, leads to the conclusion that underground nuclear explosions are applicable to mining by block-caving methods. Furthermore, material within the crushed zone should be mineable without the use of additional explosives. The mineability of material within the fracture limit is a question that is difficult to answer at present, as the degree of fracturing has not been established. Perhaps the direct approach of experimental excavation would be the best solution to the problem. The conclusions presented should be considered as hypotheses awaiting verification. There is still much to be learned from the Rainier explosion. (auth).

Book excerpt: Gnome, an underground test of a nuclear device, was located at a point 303 meters on a bearing N49 deg 43'11''E from the center of Section 34, Township 23 South, Range 30 East, New Mexico Principal Meridian, at an elevation of about 674 meters referred to mean sea level or at a depth from the surface of 361 meters. This site is about 40 km southeast of Carlsbad, New Mexico, in salt beds of the Salado formation in the Delaware Basin. The topography, geology, and structure of the site are described. Theoretical calculations indicated that the effects of the Gnome nuclear explosion would result in a cavity 17 meters in radius and total tunnel collapse to a point 125 meters from the blast. E ssentially no permanent displacement was expected in the shaft. Damage was not expected in the Shell gas well, 9.3 km distant; the potash mines, the nearest 13 km distant; nor in Carlsbad Caverns, 55 km distant. The theoretical maximum limit of displacement of a free particle at the surface was 3.035 meters. This was expected to develop fractures and visible permanent displacements. At the Gnome shot point a relatively stable cavity about 40 meters high was formed that could be used for underground storage of gas, petroleum, or waste products or to assist in mineral extraction. Surface effects from the explosion were minor, because the lithology, geologic structures, and topography were favorable for minimizing effects. The only potentiallydangerous effect of the deformation was the escape of radiation, and this could probably be prevented by additional stemming in the tunnel or by firing the shot in a vertical drill hole. It was concluded that nuclear detonations of 3 plus or minus 1-kt yield can be fired in horizontally-layered salt without damaging shafts at distances of 400 or more meters, and a drift near a nuclear detonation in salt does not suffer total collapse as it does in tuff and granite and as it was theorized would happen to a point 125 meters from the shot point. It was also concluded that a 5-kt nuclear explosion can be detonated in halite 200 meters under a water-bearing formation (aquifer) without so seriously fracturing both the upper part of the halite and the aquifer that water would penetrate downward to the cavity or to any part of the mine. The significantly different results between Gnome and Logan events, both having a yield of approximately 5-kt (Gnome 3 plus or minus 1-kt), demonstrate that different environmental characteristics will almost certainly cause differing effects from nuclear explosions. There is a critical need to reduce the necessity for interpolation by increasing both empirical and theoretical knowledge by other experiments in different environments. The transient displacement at the surface, reported to be 1.5 meters, was just half the theoretical maximum limit of 3 meters estimated for displacement of a free particle at the surface. (C.H.).
