Book excerpt: Experimental energy-averaged neutron total cross sections of 238U were evaluated from 0.044 to 20.0 MeV using rigorous numerical methods. The evaluated results are presented together with the associated uncertainties and correlation matrix. They indicate that this energy-averaged neutron total cross section is known to better than 1% over wide energy regions. There are somwewhat larger uncertainties at low energies (e.g., less than or equal to 0.2 MeV), near 8 MeV and above 15 MeV. The present evaluation is compard with values given in ENDF/B-V.

Available in PDF, EPUB and Kindle. Book excerpt: Work is reported here on the process and present results of an international evaluation of the neutron cross section standards. The evaluations include the H(n,n), 3He(n,p), 6Li(n,t), 10B(n,?), 10B(n,?1?), 197Au(n,?), 235U(n,f), and 238U(n,f) standard reactions as well as the 238U(n,?) and 239Pu(n,f) reactions. This evaluation was performed to include new experiments on the standards that have been made since the ENDF/B-VI evaluation was completed and to improve the evaluation process. Evaluations have been completed for the 6Li(n,t), 197Au(n,?) and 238U(n,?) cross sections. Also below 20 MeV the H(n,n), 235U(n,f), 238U(n,f) and 239Pu(n,f) cross sections are completed. Many of the cross sections being evaluated are used in neutron dosimetry for fluence determination. The general trend observed for the evaluations is an increase in the cross sections for most of the reactions from fractions of a percent to several percent compared with the ENDF/B-VI results.

Book excerpt: Good nuclear data are essential for accurate prediction of reactor parameters. Several cross section libraries are currently available for use with GLASS physics calculations. In recent Mark 15 and Mark 22 studies, cross section data were developed to provide more accurate buckling calculations for Mark 15 and Mark 22 charges. This report documents evaluation of these new data for universal application.

Book excerpt: The Weapons Neutron Research Facility has been used to obtain moderate-resolution total neutron cross section data for H, C, 2°8Pb, 232Th, 238U, and 242Pu over the energy range 5 to 200 MeV. Neutrons were produced by bombarding a 2.5-cm diam by 15-cm long Ta target with an 800 MeV pulsed proton beam from LAMPF. A 10.2-cm diam by 15.2-cm thick NE110 proton recoil detector was used at a flight path of 32 meters, giving a time-of-flight resolution of 60 ps/m. The total cross section results are compared to ENDF/BV evaluations and to previous data where possible.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Differential cross sections for the (p, n) reactions to the isobaric analog states (IAS) of 232Th and 238U targets were measured at 26 and 27 MeV. The analysis of the data was done in conjunction with the proton elastic and inelastic (2, 4, 6+) differential cross sections measured at 26 MeV. Because collective effects are important in this mass region, deformed coupled-channels calculations were carried out for the simultaneous analysis of the proton and neutron outgoing channels. The sensitivity of the calculations was studied with respect to the optical model parameters used in the calculations, the shape of the nuclear charge distribution, the type of coupling scheme assumed among the levels, the magnitude of the deformation parameters, and the magnitude of the isovector potentials, V1 and W1. A Lane model-consistent analysis of the data was used to infer optical potential parameters for 6- to 7-MeV neutrons. The neutron elastic differential cross sections obtained from these calculations are compared with measurements available in the literature, and with results obtained using neutron parameters from global sets reported at these energies. 7 figures, 3 tables.

Available in PDF, EPUB and Kindle. Book excerpt: This report comprises the deliverable D1.8 of the ANDES project (EURATOM contract FP7-249671) of Task 1.2 "High accuracy measurements of neutron capture cross sections" of Work Package 1. This deliverable provides evidence of a successful completion of subtasks 1.2.a and 1.2.c of Task 1.2. The main objective of these subtasks was to obtain accurate capture cross section data (i.e. capture yields) from measurements at the time-of-flight facilities GELINA and n_TOF in response to the Nuclear Data High Priority Request List. The data produced within the ANDES project will be used to produce a new evaluation of the cross section for the neutron induced capture reaction on 238U with an accuracy between 1% - 2% for neutron energies between 22 eV and 25 keV.

Available in PDF, EPUB and Kindle. Book excerpt: Accurate total and partial cross sections for 238U are important for nuclear reactor design. In the resolved resonance region, energies below 4.0 keV, these cross sections are described in terms of individual resonance parameters of which the neutron widths in the 1.5 to 4.0 keV region from various workers appear discrepant. In order to determine these widths, (0.880 to 100.0 keV) neutron transmissions through 0.076, 0.254, 1.080, and 3.620 cm thick enriched 238U samples were measured, and (0.880 to 100.0 keV) range transmissions were analyzed.
