Book Synopsis Neutron Cross Section Uncertainties in the Thermal and Resonance Regions by :
Download or read book Neutron Cross Section Uncertainties in the Thermal and Resonance Regions written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 'Atlas of Neutron Resonances', special care was expended to ensure that the resonance parameter information reproduces the various measured thermal cross sections, as well as the infinite dilute resonance integrals for Z = 1-100. In contrast, the uncertainties of the recommended quantities do not match those generated from the uncertainties of the resonance parameters. To address this problem, the present study was initiated to achieve consistency for 15 actinides and 21 structural and coolant moderator materials. This is realized by assigning uncertainties to the parameters of the negative-energy resonances and changing, if necessary, significantly the uncertainties of the low-lying positive-energy resonances. The influence of correlations between parameters on the derived uncertainties is examined and discussed.

Book Synopsis Experimental neutron resonance spectroscopy by : J Harvey
Download or read book Experimental neutron resonance spectroscopy written by J Harvey and published by Elsevier. This book was released on 2012-12-02 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental Neutron Resonance Spectroscopy deals with the experimental technique of neutron resonance spectroscopy. Pulsed accelerator time-of-flight spectrometers and gamma rays from neutron capture in resonances are discussed. Total neutron cross section measurements are presented, along with neutron scattering and capture cross-section measurements and measurements on fissile nuclides. This book is comprised of five chapters and begins with an introduction to pulsed accelerator time-of-flight spectrometers with moderated continued neutron spectra, together with the pulsed Van De Graaff. Experimental techniques used for neutron cross section measurements, including detectors and data acquisition equipment, are then outlined. Scattering measurements and capture measurements as well as gamma-ray spectra from the capture of neutrons in resonances are considered. The final chapter focuses on the detailed and varied experiments that have been performed on the complicated fission process, together with the parameters of the resonances of the fissile nuclides. This monograph will be a useful resource for spectroscopists and physicists.
Book Synopsis Neutron Cross Section Covariances in the Resonance Region by :

Book excerpt: We evaluated covariances in the neutron resonance region for capture and elastic scattering cross sections on minor structural materials, {sup 50,53}Cr, {sup 54,57}Fe and 6°Ni. Use was made of the recently developed covariance formalism based on kernel approximation along with data in the Atlas of Neutron Resonances. Our results of most interest for advanced fuel cycle applications, elastic scattering cross section uncertainties at energies around 100 keV, are on the level of about 7-10%.
Book Synopsis Neutron Cross Sections by : S Mughabghab
Download or read book Neutron Cross Sections written by S Mughabghab and published by Elsevier. This book was released on 2012-12-02 with total page 847 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutron Cross Sections, Volume 1: Neutron Resonance Parameters and Thermal Cross Sections, Part A represents the fourth edition of what was previously known as BNL-325, Neutron Cross Sections, Volume 1. This three-chapter book provides the extensive list of detailed individual resonance parameters for each isotope. The first chapter deals with the thermal cross sections and average resonance parameters, as well as the physics of thermal and resonance neutrons, with particular emphasis on evaluation methods. This chapter also includes tables of standards of capture cross sections and scattering lengths, and commonly used nuclear physics formulas. The second chapter covers the direct or valence capture and the Brink-Axel treatment of electric dipole radiation. These topics are followed by a discussion on spin-dependent scattering lengths that are of interest to solid state. The third chapter describes the Maxwellian 30-keV capture cross sections that are of importance to studies of nucleosynthesis and age of the universe. This chapter also examines the s- and p-wave average radiative widths and gamma-ray strength functions that are required in capture cross section measurements. This book will appeal to nuclear and astrophysicists.

Download or read book Neutron Cross Section Covariances in the Resolved Resonance Region written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a detailed analysis of the impact of resonance parameter uncertainties on covariances for neutron capture and fission cross sections in the resolved resonance region. Our analysis uses the uncertainties available in the recently published Atlas of Neutron Resonances employing the Multi-Level Breit-Wigner formalism. We consider uncertainties on resonance energies along with those on neutron-, radiative-, and fission-widths and examine their impact on cross section uncertainties and correlations. We also study the effect of the resonance parameter correlations deduced from capture and fission kernels and illustrate our approach on several practical examples. We show that uncertainties of neutron-, radiative- and fission-widths are important, while the uncertainties of resonance energies can be effectively neglected. We conclude that the correlations between neutron and radiative (fission) widths should be taken into account. The multi-group cross section uncertainties can be properly generated from both the resonance parameter covariance format MF32 and the cross section covariance format MF33, though the use of MF32 is more straightforward and hence preferable.

Book excerpt: We evaluated covariances for neutron capture and elastic scattering cross sections on major structural materials, 52Cr, 56Fe and 58Ni, in the resonance region which extends beyond 800 keV for each of them. Use was made of the recently developed covariance formalism based on kernel approximation along with data in the Atlas of Neutron Resonances. The data of most interest for AFCI applications, elastic scattering cross section uncertainties at energies above about few hundred keV, are on the level of about 12% for 52Cr, 7-8% for 56Fe and 5-6% for 58Ni.
