Book Description
An experimental investigation of the total neutron cross section for natural carbon was made at Kyiv Research Reactor using neutron-filtered beams with energies 24, 59, and 148 keV. The intense neutron beams formed by composite neutron filters at reactor horizontal channels )had fluxes of about 106 to 107 neutron/cm2 s at the fixed neutron energies, which enabled us to measure the neutron cross sections with accuracy better than 1 %. Transmission method was used in these measurements. The results of the measurements are presented together with the analysis of the known previous experimental data and the evaluated nuclear data from ENDF libraries. Sample thickness dependence of the observed neutron cross section, measured at the 148-keV filter, has been detected which hypothetically may be connected with existence of a very strong resonance in the 13C neutron cross section in the energy range 119 to 157 keV.

Reactor Dosimetry
Author: David W. Vehar
Publisher: ASTM International
ISBN:
Category : Science
Languages : en
Pages : 536
Book Description
"The latest edition of this popular ASTM series provides an extensive overview of the latest advances in reactor dosimetry. As operating nuclear power reactors have aged and continue to operate on extended operating licenses, new pressure vessel surveillance techniques have been required. Eastern European pressurized water reactors, especially those of the VVER-440 type, continue to have greater concerns about steel embrittlement, because of higher neutron radiation exposures than most Western European and US reactors. Accordingly, broader dosimetry studies are being made on the VVER reactors through retrospective dosimetry, ex-vessel dosimetry, and careful re-analysis of previously reported data."--Publisher's website.
