Critical Studies Of Uranium Steel And Uranium Steel Sodium Fast Reactor Cores written by P. I. Amundson and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1963 with Criticality (Nuclear engineering) categories.

Critical studies of two fast reactor cores are described: one contains uranium and steel; the other contains uranium, steel, and sodium. Experimental results are given for fission ratio, central and edge reactivity coefficients, fuel bunching, average prompt neutron lifetime, and distributed worth measurements.

Critical studies were performed with a metallic, fast reactor core designed to investigate the effects of replacing highly absorbing U-238 diluent with high-scattering, low-absorbing sodium diluent. The fuel was 15.7 wt.% enriched U-235 and the core contained 18.2 vol.% sodium and 12.68 vol.% stainless steel. The experimental program was designed to measure the effect of the material replacement on spectral indices, which consisted of the standard fission ratios, foil irradiations, and a large number of central reactivity coefficients. Other measurements included the Rossi-alpha, radial fission traverses, and edge reactivity worths of a few samples.

Critical Studies Of A Dilute Fast Reactor Core written by J. M. Gasidlo and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1961 with Aluminum categories.

Critical studies were performed on a dilute, metallic, fast reactor core. The fuel was 38.6% enriched uranium and reduced-density aluminum was used to simulate sodium coolant. The measured critical mass was 463 kg of U-235 in a 425-liter core. The main part of the experimental program consisted of measurements of the standard fission ratios, a number of central reactivity coefficients, and the prompt neutron lifetime. An additional series of experiments were performed to obtain the worths of aluminum, aluminum oxide, and sodium at various radial positions in the core.

Critical Studies Of Core B For The Enrico Fermi Atomic Power Plant written by T. A. Doyle and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1963 with Ceramic metals categories.

Critical studies of a simplified mockup of the second loading (Core B) for the Enrico Fermi fast reactor were made. The core consists of a fully enriched, uranium dioxide-stainless steel cermet clad in stainless steel and cooled by sodium. The high critical mass found for the reactor mockup led to a series of experiments on reducing neutron leakage from the core by surrounding it with different reflectors. With a nickel reflector in place, measurements were made of the reactivity worths of various engineering features of the Fermi reactor, distributed and local reactivity coefficients, various fission and capture rates and fission ratios, and the prompt-neutron lifetime. Finally, with a nickel oxide reflector in place, some of the above measurements were repeated.

Critical studies were made with a simulated, large, dilute power reactor having uranium carbide as a fuel. The uranium in the core was 30.7% enriched, and the atomic ratio of uranium to carbon was 0.946. The critical mass was 503.01 kg U-235 and the critical volume 574.47 liters. Central reactivity coefficients, effective fission cross-section ratios, heterogeneity effects, reactivity worth of distributed materials, foil irradiations, and the average prompt neutron lifetime were measured. Multigroup calculations using the Yiftah, Okrent, and Moldauer, cross-section set overestimate k for the critical configuration by 4.7%.

Assembly 43 is the second two-zone core built in the ZPR-III facility. The central zone and the low-density axial blanket were designed to simulate a large power-breeder reactor. Criticality was achieved by an annular driver, while an interposed buffer modified the spectrum of the neutrons diffusing from the driver to the central zone.

In this book, Thomas B. Cochran takes a critical look at the economic and environmental arguments which have been made in favour of an early introduction of the liquid metal fast breeder reactor (LMFBR) as a central component of the United States electrical energy system. First published in 1974, Cochran presents LMFBR as having no environmental advantage over light water reactors and the high temperature gas reactor and seriously questions the economic advantages. This title should be a useful for students interested in environment and sustainability studies, and it is a valuable resource for discussions of future energy strategy.

This study was conducted to determine what properties of a previously studied dilute power reactor could be duplicated in a smaller two-zone assembly. Reactivity measurements performed included determinations of plate-orientation worth, homogeneity corrections, reactor-segment worths, central reactivity coefficients, and radial worth distributions of axial columns of core materials. Spectral index determinations included: central fission ratios, nuclear track emulsion measurements, fission counter traverses, Rossi-alpha measurements, sodium activation, and natural and enriched uranium foil measurements.
