Download or read book Critical Studies of a 450 liter Uranium Oxide Fast Reactor Core written by A. L. Hess and published by . This book was released on 1961 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of studies with ZPR-IH Assembly 29, a mockup of a typical, dilute UO2-fueled fast reactor, are reported. The assembly consisted of a 454-liter cylindrical core, blanketed with depleted uranium, with a critical mass of 42l kg U-235. Experiments included measurements of fission rates, material reactivity worths, and Rossi alpha. The results of multi-group calculations using the present Argonne cross-section sets are presented, and discrepancies between experimental results and calculations are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1963 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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%.

This book was released on 1962 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical comparison of measured and calculated central fission ratios for 18 ZPR-III fast reactor assemblies was made with the object of examining the accuracy of computation of spectra and of the fission cross sections used. This comparison uses fission ratios measured with Kirn absolute fission chambers and computed with ANL cross section Set 635.
