This book was released on 1965 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new activation technique has been developed for the measurement of the ratio of the capture cross section of uranium-238 and the fission cross section of uranium-235 in zero-energy fast reactors. This work was initiated because of the long-standing discrepancy between calculated values in this ratio and radiochemically measured values. The new technique is a direct counting method which does not involve chemical separation in any way. Measurements have been made in four ZPR-3 fast reactor assemblies, two with hard spectra and two with soft spectra. In all four cases the measured ratio was slightly higher, on the average, than the calculated value. This is in strong contrast with the past radiochemical measurements in ZPR-3 assemblies, which gave vales 16% less than calculation.

Download or read book Determination of Absolute Fission Cross Section Ratios Using the Method of Threshold Cross Sections written by and published by . This book was released on 1973 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fission cross section measurements for a collection of uranium and plutoninm isotopes are presertly being made at LLL by using the 100-MeV electron linear accelerator as a pulsed source for neutrons. The cross sections are measured as a function of neutron energy from 15 MeV down to thermal energy by using the time-of-flight technique. For neutron energies above 1 MeV, a new method for determining absolute fission cross section ratios is used. This method, called the method of threshold cross sections, gives absolute fission cross section ratios without the need for determing the absolute masses of flssionable material within flssion chambers. An explanation of the threshold cross section method is given, and an example is cited for the absolute ratio sigma /sub f/(238): sigma /sub f/ (235) above 1 MeV. (auth).

This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The error information from the recent measurements of the fission cross section ratios of nine isotopes, 23°Th, 232Th, 233U, 234U, 236U, 238U, 237Np, 239Pu, and 242Pu, relative to 235U at 14.74 MeV neutron energy was used to calculate their correlations. The remaining 36 non-trivial and non-reciprocal cross section ratios and their errors were determined and compared to evaluated (ENDF/B-V) values. There are serious differences but it was concluded that the reduction of three of the evaluated cross sections would remove most of them. The cross sections to be reduced are 23°Th - 13%, 237Np - 9.6% and 239Pu - 7.6%. 5 refs., 6 tabs.

Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.
