Available in PDF, EPUB and Kindle. Book excerpt: A series of experiments was performed at the Los Alamos critical assembly facility in the early 1950s to determine the critical mass of highly enriched uranium spheres surrounded by thin reflectors of various materials. The objective of these experiments was to obtain a precision graph of the critical mass of highly enriched uranium metal as a function of reflector thickness and to generate transport cross sections for the reflector material. Thirteen configurations are described and evaluated under ICSBEP identifier, HEU-MET-FAST-085; two with 1.98-inch-thick and 4.158-inch-thick copper reflectors, two with 2- and 4-inch-thick cast iron reflectors, one with a 1.945-inch-thick nickel reflector, two with 1.88- and 2.02-inch-thick nickel-copper-zinc alloy reflectors, one with a 1.81-inch-thick thorium reflector, two with 2-inch-thick and 4-inch-thick tungsten alloy reflectors, two with 2-inch-thick and 4.075-inch-thick zinc reflectors, and one with a 2-inch-thick tungsten alloy reflector surrounded by a 2-inch-thick cast iron reflector. All configurations were slightly subcritical with measured multiplications ranging from 20 to 162. Analyses were performed in which uncertainty associated with six different parameters was evaluated; namely, extrapolation to uranium critical mass, uranium density, 235U enrichment, reflector density, reflector thickness, and reflector impurities were considered. Uncertainty in cast-iron alloying elements was also considered when appropriate. In addition to the idealizations made by the experimenters, two simplifications were also made to the benchmark models that resulted in a small bias and additional uncertainty. First of all, since impurities in core and reflector materials are only estimated, they are not included in the benchmark models. Secondly, the room, support structure, and other possible surrounding equipment were not included in the model. Bias values that result from these two simplifications were determined and associated uncertainty in the bias values were included in the overall uncertainty in benchmark keff values. Bias values range from 0.0021?k low to 0.0016?k high. Overall uncertainties range from? 0.0023 to? 0.0064. Major contributors to the overall uncertainty include uncertainty in the extrapolation to the uranium critical mass and the uranium density. Results are summarized in the following figure. The 3 configurations described and evaluated in HEU-MET-FAST-085 are judged to be acceptable for use as criticality safety benchmark experiments and should be valuable integral benchmarks for nuclear data testing of the various reflector materials. Details of the benchmark models, uncertainty analyses, and final results are given in this paper.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1983, this book presents both the technical and political information necessary to evaluate the emerging threat to world security posed by recent advances in uranium enrichment technology. Uranium enrichment has played a relatively quiet but important role in the history of efforts by a number of nations to acquire nuclear weapons and by a number of others to prevent the proliferation of nuclear weapons. For many years the uranium enrichment industry was dominated by a single method, gaseous diffusion, which was technically complex, extremely capital-intensive, and highly inefficient in its use of energy. As long as this remained true, only the richest and most technically advanced nations could afford to pursue the enrichment route to weapon acquisition. But during the 1970s this situation changed dramatically. Several new and far more accessible enrichment techniques were developed, stimulated largely by the anticipation of a rapidly growing demand for enrichment services by the world-wide nuclear power industry. This proliferation of new techniques, coupled with the subsequent contraction of the commercial market for enriched uranium, has created a situation in which uranium enrichment technology might well become the most important contributor to further nuclear weapon proliferation. Some of the issues addressed in this book are: A technical analysis of the most important enrichment techniques in a form that is relevant to analysis of proliferation risks; A detailed projection of the world demand for uranium enrichment services; A summary and critique of present institutional non-proliferation arrangements in the world enrichment industry, and An identification of the states most likely to pursue the enrichment route to acquisition of nuclear weapons.

Book excerpt: In the wake of the Fukushima Daiichi nuclear power plant accident, questions are being raised about the future of the uranium market, including as regards the number of reactors expected to be built in the coming years, the amount of uranium required to meet forward demand, the adequacy of identified uranium resources to meet that demand and the ability of the sector to meet reactor requirements in a challenging investment climate. This 24th edition of the "Red Book", a recognised world reference on uranium jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, provides analyses and information from 42 producing and consuming countries in order to address these and other questions. It offers a comprehensive review of world uranium supply and demand as well as data on global uranium exploration, resources, production and reactor-related requirements. It also provides substantive new information on established uranium production centres around the world and in countries developing production centres for the first time. Projections of nuclear generating capacity and reactor-related requirements through 2035, incorporating policy changes following the Fukushima accident, are also featured, along with an analysis of long-term uranium supply and demand issues

Book excerpt: The book has two themes based on my direct participation as Chairman of the Design Authority in Iraq's Atomic Organization (1987-1992). The first theme focuses on Iraq's engineering capacity to design and build the Al-Atheer nuclear facilities, without any prior experience in this field and with no foreign assistance. Al Atheer was principally involved in the nuclear weaponization program and function as a materials research center. Al Atheer was the Iraqi equivalent to Los Alamos, Research and development project that produced the first US atomic bombs in 1946. All other Iraqi nuclear facilities were designed and built by the Russians, French, Italians, Yugoslavs, and Brazilians. The second theme is about successfully passive defence plan( camouflage ) the Al Atheer facilities through 42 days of air raids during the second gulf war 1991. US intelligence and Satellite surveillance deemed Al Atheer facilities to other (non-nuclear) industrial programs. Al Atheer discovered through united inspection missions after eight months of ceasefire.

Download or read book Saddam's Bombmaker written by Jeff Stein and published by Simon and Schuster. This book was released on 2001-06-24 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Iraqi scientist who designed Baghdad's nuclear bomb tells how he did it in secret with the cynical help of U.S., French, German, and British suppliers and experts, and kept it hidden from U.N. inspectors after the Gulf War. Today, he says, Saddam Hussein is only months away from making a workable bomb and has every intention of using it. Don't tell me about the law. The law is anything I write on a scrap of paper." Saddam Hussein In 1994, after twenty years developing Iraq's atomic weapon, Dr. Khidhir Hamza made a daring escape to warn the CIA of Saddam's nuclear ambitions...only to be ridiculed and turned away! After a harrowing journey across three continents with Iraqi agents on his trail, Hamza finally came in from the cold at the U.S. embassy in Hungary. Now he tells a frightening story that U.S. officials have finally come to believe: that Saddam is still feverishly at work on the bomb and, if pushed to the wall, will use it. Dr. Hamza also presents a startling, unprecedented portrait of Saddam himself his drunken rages, his women, his fear of germs, and his cold-blooded murder of underlings. A former resident of the presidential palace, Hamza is the only defector who has lived to write a firsthand, intimate portrait of the Iraqi inner circle, its spies and hit men, and their brutal chief. Saddam's Bombmaker is also a saga of one man's journey through the circles of hell. Educated at MIT and Florida State University, dedicated to a life of peaceful teaching in America, Dr. Hamza relates how the regime ordered him home, seduced him into a pampered life as an atomic energy official, and forced him to design a bomb. The price of refusal was torture. As the father of the Iraqi bomb, Dr. Hamza designed a device from scratch with the help of World War Twoera blueprints from America's Los Alamos labs, all the while planning an escape. Privately, he and his colleagues believed they could procrastinate long enough to outlive Saddam. But the dictator outmaneuvered them, whipping the scientists into a crash program to build a crude bomb that could be dropped on Israel. Had U.S. and Allied forces not quickly mobilized for Desert Storm, Dr. Hamza relates, Saddam may well have succeeded; except for sufficient uranium, the device was ready. It still is. Dr. Hamza's tale of his escape, his first bungled contact with CIA agents, and his flight abroad will keep readers turning pages toward a climax worthy of a well-crafted spy thriller. Along the way, he reveals: The West's "don't ask, just sell" attitude toward Iraq's nuclear, chemical, and biological programs as long as it was fighting Iran. How Iraq tested biological and chemical weapons on human subjects. How the Palestinian Liberation Organization (PLO) tried to recruit Dr. Hamza to make a bomb. Baghdad's secret program to break into U.S. and other foreign computer systems. Saddam's Bombmaker is not only a shocking political and scientific exposé -- it is a riveting adventure tale.
