Book excerpt: Energy distributions and energy release rates of fission product gammas and energy release rates of the fission product betas are presented in tabular and graphical form, and the computation methods are outlined in detail. The data given for beta and gamma decay rates pertain directly to the thermal fission of U/ sup 235/. The possible effects of neutron energy spectra, other than thermal, and neutron flux level upon the fission product decay rates were examined, and the results are reported. The importance of bremsstrahlung caused by beta particles from fission products and the effect of photoneutron production due to the photonuclear reactions of the fission product gammas with D or Re were studied. Methods of evaluating these effects in the reactor are briefly described. (J.E.D.).

Available in PDF, EPUB and Kindle. Book excerpt: Calculations and measurements of delayed beta and gamma activities and spectra following nuclear fission are presented. There is good agreement between various calculations and measurements of gamma activity and spectra of U-235 fission products. There is a degree of agreement in calculated and measured beta activity. U-235 fission product beta and gamma activities are integrated over time to determine the total number of betas and the total gamma energy emitted per fission. Analysis of various information reveals that: (1) Gamma activity and spectra following fission of U-235 by thermal neutrons coincide with that of fission of U-235 by fission spectrum neutrons. (2) Gamma activities of U-235 fission products and Pu-239 fission products are identical within limits of experimental error. (3) Initial beta and gamma activities of U-238 fission products are approximately a factor of 2 higher than for U-235 fission products.

Available in PDF, EPUB and Kindle. Book excerpt: A comparison is made of activity and the computed photon energy radiation rates for 1 hr to 3 years after fission. A comparison is also made of the number of fissions and neutron capture/fission ratio for neutron bombarded samples of U-235 and of U-235 + U-238 as determined by the decay curve analyses and by radiochemical analyses. The computed decay curves for 104 fissions from slow-neutron fission of U-235 using the USNRDL 4-pi Ionization Chamber is presented.

Download or read book Medical Isotope Production Without Highly Enriched Uranium written by National Research Council and published by National Academies Press. This book was released on 2009-06-27 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the product of a congressionally mandated study to examine the feasibility of eliminating the use of highly enriched uranium (HEU2) in reactor fuel, reactor targets, and medical isotope production facilities. The book focuses primarily on the use of HEU for the production of the medical isotope molybdenum-99 (Mo-99), whose decay product, technetium-99m3 (Tc-99m), is used in the majority of medical diagnostic imaging procedures in the United States, and secondarily on the use of HEU for research and test reactor fuel. The supply of Mo-99 in the U.S. is likely to be unreliable until newer production sources come online. The reliability of the current supply system is an important medical isotope concern; this book concludes that achieving a cost difference of less than 10 percent in facilities that will need to convert from HEU- to LEU-based Mo-99 production is much less important than is reliability of supply.

This book was released on 2012-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1980s, the National Cancer Institute initiated an investigation of cancer risks in populations near 52 commercial nuclear power plants and 10 Department of Energy nuclear facilities (including research and nuclear weapons production facilities and one reprocessing plant) in the United States. The results of the NCI investigation were used a primary resource for communicating with the public about the cancer risks near the nuclear facilities. However, this study is now over 20 years old. The U.S. Nuclear Regulatory Commission requested that the National Academy of Sciences provide an updated assessment of cancer risks in populations near USNRC-licensed nuclear facilities that utilize or process uranium for the production of electricity. Analysis of Cancer Risks in Populations near Nuclear Facilities: Phase 1 focuses on identifying scientifically sound approaches for carrying out an assessment of cancer risks associated with living near a nuclear facility, judgments about the strengths and weaknesses of various statistical power, ability to assess potential confounding factors, possible biases, and required effort. The results from this Phase 1 study will be used to inform the design of cancer risk assessment, which will be carried out in Phase 2. This report is beneficial for the general public, communities near nuclear facilities, stakeholders, healthcare providers, policy makers, state and local officials, community leaders, and the media.
