Download or read book K Calculations for 22 ZPR III Fast Reactor Assemblies Using ANL Cross section Set 635 written by W. G. Davey and published by . This book was released on 1962 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Yiftah, Okrert, and Moldauer cross-section set (ANL Set 135) was modified to include new measurements of nu and alpha for U235, and to include, in an approximate manner, Hummel, Rago, and Meneghetti's corrections for flux depression at resonance energies in aluminum and stainless steel. This modified set, ANL Set 635, was used to compute values of k for 22 ZPR-III assemblies of widely varying composition. The DSN neutron transport code was used in spherical geometry and the S4 approximation; shape factors were used to convert from cylindrical to spherical geometry. Seventeen of the calculated values of k lie within plus or minus 1% of a mean value of 1.003, and the remaining 5 lie within plus or minus 2%. In terms of prediction of critical mass, it appears that the procedure used here can achieve an accuracy of 5% to 10% for a wide range of U235-fueled assemblies.

Book excerpt: Fast Breeder Reactors presents the proceedings of the London Conference on Fast Breeder Reactors organized by the British Nuclear Energy Society on May 17-19, 1966. The book covers topics about the place of the fast breeder reactor in the energy programs (including fuel cycles), operating experience with fast reactors; the design of fast reactor prototypes and power reactors (including advanced concepts with coolants other than sodium); fast reactor physics; and fuel technology. The text also describes topics about sodium technology and engineering of fast reactors and provides definitions of fast reactor breeding and inventory. Civil engineers will find the book useful.

Download or read book A Comparison of Experimental and Calculated Prompt Neutron Lifetimes and Central Reactivity Coefficients in ZPR III Assemblies and Their Relationship to Other Reactor Parameters written by W. G. Davey and published by . This book was released on 1963 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental parameters of ZPR-III fast reactor assemblies were compared with those calculated through use of a cross-section set derived from that of Yiftah, Okrent, and Moldauer, and initially used for a study of the critical sizes of ZPR-III assemblies. This cross-section set was also used to study central fission ratios in ZPR-III assemblies. The analysis was extended to prompt neutron lifetimes and the relative reactivity effects of the substitution of materials at the reactor centers. The results of the work were examined in conjunction with those of the critical size and fission ratio studies.

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.

Available in PDF, EPUB and Kindle. Book excerpt: A series of calculations, centered around a possible zoned critical in a ZPR-III-type machine, is presented and discussed. Criteria of selection for equivalent samples and optimum drivers are discussed. The conclusion is drawn that measurements on a combination of one or more zoned critical, and the careful computation of correction terms, can yield nearly all the experimental data which might be derived from a full-scale, all-sample critical without significant loss of accuracy. The major exception is an experimental value for critical mass.
