Download or read book Delayed Neutron Emission Measurements for U-235 and Pu-239 written by Yong Chen and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The delayed neutron emission rates of U-235 and Pu-239 samples were measured accurately from a thermal fission reaction. A Monte Carlo calculation using the Geant4 code was used to demonstrate the neutron energy independence of the detector used in the counting station. A set of highly purified actinide samples (U-235 and Pu-239) was irradiated in these experiments by using the Texas A & M University Nuclear Science Center Reactor. A fast pneumatic transfer system, an integrated computer control system, and a graphite-moderated counting system were constructed to perform all these experiments. The calculated values for the five-group U-235 delayed neutron parameters and the six-group Pu-239 delayed neutron parameters were compared with the values recommended by Keepin et al. (1957) and Waldo et al. (1981). These new values differ slightly from literature values. The graphite-moderated counting station and the computerized pneumatic system are now operational for further delayed neutron measurement.

Download or read book Management and Disposition of Excess Weapons Plutonium written by National Academy of Sciences and published by National Academies Press. This book was released on 1995-08-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the next decade, many thousands of U.S. and Russian nuclear weapons are slated to be retired as a result of nuclear arms reduction treaties and unilateral pledges. Hundreds of tons of plutonium and highly enriched uranium will no longer be needed for weapons purposes and will pose urgent challenges to international security. This is the supporting volume to a study by the Committee on International Security and Arms Control which dealt with all phases of the management and disposition of these materials. This technical study concentrates on the option for the disposition of plutonium, looking in detail at the different types of reactors in which weapons plutonium could be burned and at the vitrification of plutonium, and comparing them using economic, security and environmental criteria.

Download or read book Analytical Applications for Delayed Neutrons written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical formulations that describe the time dependence of neutron populations in nuclear materials contain delayed-neutron dependent terms. These terms are important because the delayed neutrons, even though their yields in fission are small, permit control of the fission chain reaction process. Analytical applications that use delayed neutrons range from simple problems that can be solved with the point reactor kinetics equations to complex problems that can only be solved with large codes that couple fluid calculations with the neutron dynamics. Reactor safety codes, such as SIMMER, model transients of the entire reactor core using coupled space-time neutronics and comprehensive thermal-fluid dynamics. Nondestructive delayed-neutron assay instruments are designed and modeled using a three-dimensional continuous-energy Monte Carlo code. Calculations on high-burnup spent fuels and other materials that contain a mix of uranium and plutonium isotopes require accurate and complete information on the delayed-neutron periods, yields, and energy spectra. A continuing need exists for delayed-neutron parameters for all the fissioning isotopes.

This book was released on 1955 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delayed neutron studies have been made in the Experimental Breeder Reactor (EBR), using a conventional sample transfer system and a neutron counter comprised of BF3 tubes in a graphite geometry. Samples of U-235, U-233, U-238, Pu, and Th were irradiated in a fast flux; samples of U-235, U-233, and Pu were irradiated in a thermal flux.

This book was released on 1988-02-01 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes hazards from radon progeny and other alpha-emitters that humans may inhale or ingest from their environment. In their analysis, the authors summarize in one document clinical and epidemiological evidence, the results of animal studies, research on alpha-particle damage at the cellular level, metabolic pathways for internal alpha-emitters, dosimetry and microdosimetry of radionuclides deposited in specific tissues, and the chemical toxicity of some low-specific-activity alpha-emitters. Techniques for estimating the risks to humans posed by radon and other internally deposited alpha-emitters are offered, along with a discussion of formulas, models, methods, and the level of uncertainty inherent in the risk estimates.

Download or read book The Plutonium Files written by Eileen Welsome and published by Delta. This book was released on 2010-10-20 with total page 814 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the vast wartime factories of the Manhattan Project began producing plutonium in quantities never before seen on earth, scientists working on the top-secret bomb-building program grew apprehensive. Fearful that plutonium might cause a cancer epidemic among workers and desperate to learn more about what it could do to the human body, the Manhattan Project's medical doctors embarked upon an experiment in which eighteen unsuspecting patients in hospital wards throughout the country were secretly injected with the cancer-causing substance. Most of these patients would go to their graves without ever knowing what had been done to them. Now, in The Plutonium Files, Pulitzer Prize-winning reporter Eileen Welsome reveals for the first time the breadth of the extraordinary fifty-year cover-up surrounding the plutonium injections, as well as the deceitful nature of thousands of other experiments conducted on American citizens in the postwar years. Welsome's remarkable investigation spans the 1930s to the 1990s and draws upon hundreds of newly declassified documents and other primary sources to disclose this shadowy chapter in American history. She gives a voice to such innocents as Helen Hutchison, a young woman who entered a prenatal clinic in Nashville for a routine checkup and was instead given a radioactive "cocktail" to drink; Gordon Shattuck, one of several boys at a state school for the developmentally disabled in Massachusetts who was fed radioactive oatmeal for breakfast; and Maude Jacobs, a Cincinnati woman suffering from cancer and subjected to an experimental radiation treatment designed to help military planners learn how to win a nuclear war. Welsome also tells the stories of the scientists themselves, many of whom learned the ways of secrecy on the Manhattan Project. Among them are Stafford Warren, a grand figure whose bravado masked a cunning intelligence; Joseph Hamilton, who felt he was immune to the dangers of radiation only to suffer later from a fatal leukemia; and physician Louis Hempelmann, one of the most enthusiastic supporters of the plan to inject humans with potentially carcinogenic doses of plutonium. Hidden discussions of fifty years past are reconstructed here, wherein trusted government officials debated the ethical and legal implications of the experiments, demolishing forever the argument that these studies took place in a less enlightened era. Powered by her groundbreaking reportage and singular narrative gifts, Eileen Welsome has created a work of profound humanity as well as major historical significance. From the Hardcover edition.
