Book Description
The primary aim of the present study was to put fission yields from U235 on a quantitative basis. The absolute fission yield of a convenient reference nuclide, 12.8d Ba140, was measured in a more direct manner than had previously been done. Fission yields in U235 and U238 were compared for a number of nuclides to determine whether or not the fission yields in natural uranium in a thermal neutron reactor might be influenced appreciably by fast fission of U238. As a result of this last experiment it was noted that the fission yield curves of U235 and U238 have significantly different shapes.

Measurement of Delayed Neutron Yields in Plutonium, Uranium-233, Uranium-238, and Thorium Relative to Yield in Uranium-235
Author: G. S. Brunson
Publisher:
ISBN:
Category : Delayed neutrons
Languages : en
Pages : 32
Book Description
Delayed neutron studies have been made in the Experimental Breeder Reactor (EBR), using a conventional sample transfer system and a neutron counter comprised of BF3 tubes in a graphite geometry. Samples of U-235, U-233, U-238, Pu, and Th were irradiated in a fast flux; samples of U-235, U-233, and Pu were irradiated in a thermal flux.

Gamma-ray Spectra of the Products of Fast Neutron Fission of U235 and U238 at Selected Times After Fission

Pages : 28
Book Description
Experimental measurements of the gamma-ray pulse height distributions due to the products of fast-neutron-induced fission of Uranium-235 and Uranium-238 are presented. The measurements were made at nine selected times after fission from 15 minutes to 3 days. Irradiation times and counting intervals were chosen to minimize saturation and decay effects. The experimental data were used to calculate 100 energy bin distributions of the absolute number of photons/fission-sec. by means of absolute calibrations of the collimated NaI(T1) detector. The number of fissions in each sample was determined radiochemically. Machine computation was used extensively.
