Physics of Nuclear Explosives


Book Description

This book (an improved English version of the one published in Portuguese in 2009) deals with topics essential to understanding the physics of nuclear explosives. Prepared based on strictly academic scientific activity, it is intended for those who wish to know more deeply the theory and physical processes involved in nuclear explosions. The main topics covered are: neutronic and criticality (neutron transport); hydrodynamics and thermodynamics at high temperatures and densities; dense and heavy plasmas; opacity and transport of thermal radiation; hydrodynamic theory of chemical detonations; shock waves, dynamic compression of solids, implosions; statistics of fission chain reactions; and inertial confinement fusion (thermonuclear detonations). Three types of explosives are analyzed: Pure fission explosives, the so-called "boosted bombs" (with the introduction of deuterium-tritium into the fissile mass) and thermonuclear explosives. Results of complex numerical and computational simulations (many of which presumably have never been published in the open scientific literature) are presented and discussed.""The Physics of Nuclear Explosives" provides a rather comprehensive account of the physical principles involved in nuclear detonations, including both fission and fusion weapons. The author has broken new ground in presenting the results of his numerical simulations of nuclear detonations and characterizations of particular weapons, such as the W-87 warhead."

Effects of Nuclear Earth-Penetrator and Other Weapons


Book Description

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.




Project Plowshare


Book Description

Inspired by President Dwight D. Eisenhower's "Atoms for Peace" speech, scientists at the Atomic Energy Commission and the University of California's Radiation Laboratory began in 1957 a program they called Plowshare. Joined by like-minded government officials, scientists, and business leaders, champions of "peaceful nuclear explosions" maintained that they could create new elements and isotopes for general use, build storage facilities for water or fuel, mine ores, increase oil and natural gas production, generate heat for power production, and construct roads, harbors, and canals. By harnessing the power of the atom for nonmilitary purposes, Plowshare backers expected to protect American security, defend U.S. legitimacy and prestige, and ensure access to energy resources. Scott Kaufman's extensive research in nearly two dozen archives in three nations shows how science, politics, and environmentalism converged to shape the lasting conflict over the use of nuclear technology. Indeed, despite technological and strategic promise, Plowshare's early champions soon found themselves facing a vocal and powerful coalition of federal and state officials, scientists, industrialists, environmentalists, and average citizens. Skeptical politicians, domestic and international pressure to stop nuclear testing, and a lack of government funding severely restricted the program. By the mid-1970s, Plowshare was, in the words of one government official, "dead as a doornail." However, the thought of using the atom for peaceful purposes remains alive.




Monitoring Nuclear Weapons and Nuclear-Explosive Materials


Book Description

In this study, CISAC tackles the technical dimensions of a longstanding controversy: To what extent could existing and plausibly attainable measures for transparency and monitoring make possible the verification of all nuclear weaponsâ€"strategic and nonstrategic, deployed and nondeployedâ€"plus the nuclear-explosive components and materials that are their essential ingredients? The committee's assessment of the technical and organizational possibilities suggests a more optimistic conclusion than most of those concerned with these issues might have expected.




The Case for U.S. Nuclear Weapons in the 21st Century


Book Description

“An excellent contribution to the debate on the future role of nuclear weapons and nuclear deterrence in American foreign policy.” ―Contemporary Security Policy This book is a counter to the conventional wisdom that the United States can and should do more to reduce both the role of nuclear weapons in its security strategies and the number of weapons in its arsenal. The case against nuclear weapons has been made on many grounds—including historical, political, and moral. But, Brad Roberts argues, it has not so far been informed by the experience of the United States since the Cold War in trying to adapt deterrence to a changed world, and to create the conditions that would allow further significant changes to U.S. nuclear policy and posture. Drawing on the author’s experience in the making and implementation of U.S. policy in the Obama administration, this book examines that real-world experience and finds important lessons for the disarmament enterprise. Central conclusions of the work are that other nuclear-armed states are not prepared to join the United States in making reductions, and that unilateral steps by the United States to disarm further would be harmful to its interests and those of its allies. The book ultimately argues in favor of patience and persistence in the implementation of a balanced approach to nuclear strategy that encompasses political efforts to reduce nuclear dangers along with military efforts to deter them. “Well-researched and carefully argued.” ―Foreign Affairs
