Plutonium: A History of the World'S most Dangerous Element
by Jeremy BernsteinWhen plutonium was first manufactured at Berkeley in the spring of 1941, there was so little of it that it was not visible to the naked eye. It took a year to accumulate enough so that one could actually see it. Now there is so much that we don't know what to do to get rid of it. We have created a monster. The history of plutonium is as strange as the element itself. When scientists began looking for it, they did so simply in the spirit of inquiry, not certain whether there were still spots to fill on the periodic table. But the discovery of fission made it clear that this still-hypothetical element would be more than just a scientific curiosity--it could be a powerful nuclear weapon. As it turned out, it is good for almost nothing else. Plutonium's nuclear potential put it at the heart of the World War II arms race--the Russians found out about it through espionage, the Germans through independent research, and everybody wanted some. Now, nearly everyone has some--the United States alone has about 47 metric tons--but it has almost no uses besides warmongering. How did the product of scientific curiosity become such a dangerous burden? In his new history of this complex and dangerous element, noted physicist Jeremy Bernstein describes the steps that were taken to transform plutonium from a laboratory novelty into the nuclear weapon that destroyed Nagasaki. This is the first book to weave together the many strands of plutonium's story, explaining not only the science but the people involved.
Plutonium: How Nuclear Power’s Dream Fuel Became a Nightmare
by Jungmin Kang Frank von Hippel Masafumi TakuboThis book provides a readable and thought-provoking analysis of the issues surrounding nuclear fuel reprocessing and fast-neutron reactors, including discussion of resources, economics, radiological risk and resistance to nuclear proliferation. It describes the history and science behind reprocessing, and gives an overview of the status of reprocessing programmes around the world. It concludes that such programs should be discontinued. While nuclear power is seen by many as the only realistic solution to the carbon emission problem, some national nuclear establishments have been pursuing development and deployment of sodium-cooled plutonium breeder reactors, and plutonium recycling. Its proponents argue that this system would offer significant advantages relative to current light water reactor technology in terms of greater uranium utilization efficiency, and that separating out the long-lived plutonium and other transuranics from spent fuel and fissioning them in fast reactors would greatly reduce the duration of the toxicity of radioactive waste. However, the history of efforts to deploy this system commercially in a number of countries over the last six decades has been one of economic and technical failure and, in some cases, was used to mask clandestine nuclear weapon development programs. Covering topics of significant public interest including nuclear safety, fuel storage, environmental impact and the spectre of nuclear terrorism, this book presents a comprehensive analysis of the issue for nuclear engineers, policy analysts, government officials and the general public. "Frank von Hippel, Jungmin Kang, and Masafumi Takubo, three internationally renowned nuclear experts, have done a valuable service to the global community in putting together this book, which both historically and comprehensively covers the “plutonium age” as we know it today. They articulate in a succinct and clear manner their views on the dangers of a plutonium economy and advocate a ban on the separation of plutonium for use in the civilian fuel cycle in view of the high proliferation and nuclear-security risks and lack of economic justification." (Mohamed ElBaradei, Director General, International Atomic Energy Agency (1997-2009), Nobel Peace Prize (2005))"The 1960s dream of a ‘plutonium economy’ has not delivered abundant low-cost energy, but instead has left the world a radioactive legacy of nuclear weapons proliferation and the real potential for nuclear terrorism. Kang, Takubo, and von Hippel explain with power and clarity what can be done to reduce these dangers. The governments of the remaining countries whose nuclear research and development establishments are still pursuing the plutonium dream should pay attention.” (Senator Edward Markey, a leader in the US nuclear-disarmament movement as a member of Congress since 1976)"The authors have done an invaluable service by putting together in one place the most coherent analysis of the risks associated with plutonium, and the most compelling argument for ending the practice of separating plutonium from spent fuel for any purpose. They have given us an easily accessible history of the evolution of thinking about the nuclear fuel cycle, the current realities of nuclear power around the world and, arguably most important, a clear alternative path to deal with the spent fuel arising from nuclear reactors for decades to centuries to come."

Pneumatic Conveying: Basics, Design and Operation of Plants
by Peter HilgrafBulk materials are processed and refined in many industrial plants. They are transported back and forth between the various process steps. If bulk materials are dust-fine to coarse-grained, they can be transported pneumatically through pipelines with flowing gas - over distances of several metres to several kilometres.This book introduces the basics of pneumatic conveying, the construction of plants and their operation. The first three chapters deal with the physical properties of the bulk material and the conveying gas as well as their behaviour in gas-solid systems. The following chapter describes the application of these basics in pneumatic conveying: starting with different flow forms, via processes at the plug, up to pressure loss in pneumatic conveying lines. The following sections are devoted, among other things, to calculation approaches for the transfer of test models to large-scale systems, as well as to modern dense-phase conveying methods in which material to be conveyed moves at low speed in the form of threads, plugs or flowing. Separate chapters deal with the design of pneumatic conveying systems and various forms and causes of their wear.The book offers calculation examples for many topics and is state of the art. It is aimed at engineers, plant constructors and operators of product lines with pneumatic conveying. They benefit from the author's decades of experience in the development and design of plants with new conveying processes.
Pneumonia Before Antibiotics: Therapeutic Evolution and Evaluation in Twentieth-Century America
by Scott H. PodolskyPneumonia—Osler's "Captain of the Men of Death" and still the leading infectious cause of death in the United States—has until now received scant attention from historians. In Pneumonia Before Antibiotics, clinician-historian Scott H. Podolsky uses pneumonia's enduring prevalence and its centrality to the medical profession's therapeutic self-identity to examine the evolution of therapeutics in twentieth-century America. Focusing largely on the treatment of pneumonia in first half of the century with type-specific serotherapy, Podolsky provides insight into the rise and clinical evaluation of therapeutic "specifics," the contested domains of private practice and public health, and-as the treatment of pneumonia made the transition from serotherapy to chemotherapy and antibiotics—the tempo and mode of therapeutic change itself. Type-specific serotherapy, founded on the tenets of applied immunology, justified by controlled clinical trials, and grounded in a novel public ethos, was deemed revolutionary when it emerged to replace supportive therapeutics. With the advent of the even more revolutionary sulfa drugs and antibiotics, pneumonia ceased to be a public health concern and became instead an illness treated in individual patients by individual physicians. Podolsky describes the new therapeutics and the scientists and practitioners who developed and debated them. He finds that, rather than representing a barren era in anticipation of some unknown transformation to come, the first decades of the twentieth-century shaped the use of, and reliance upon, the therapeutic specific throughout the century and beyond. This intriguing study will interest historians of medicine and science, policymakers, and clinicians alike.
