An Integral Experiment to Measure the Tritium Production From Li7 By 14 Mev Neutrons in a Lithium Deuteride Sphere

Description: A sphere of LiD 2 feet in diameter was irradiated by 2 x 10<sup>15 14 Mev neutrons. Samples of Li<sup>7 metal were positioned at various radii for the irradiation. An analysis of these samples for tritium led to a determination of the number of tritons produced by 14 Mev neutrons acting on Li<sup>7 in a LiD system.

A Measurement of the [Lithium-7] Cross-Section for Several Neutron Energies From 4 to 15 Mev by Absolute Counting Techniques

Description: A measurement of the [Lithium-7] reaction cross section by absolute counting of the tritium betas is described. The cross section was measured at several neutron energies between 4 Mev and 15 Mev. A comparison with results by emulsion techniques is given.

Nuclear Propulsion Test Reactor Kiwi-A Neutronic Studies

Description: Critical conditions were obtained for a series of uranium-graphite fueled assemblies in the C/Oy range 150 to 500 with thick graphite reflectors and Be or D2O islands. Perturbations were studied in order to find the effect on reactivity of geometrical changes and engineering features. Information from these studies was used to develop a mock-up of an optimum reactor geometry for the first rocket reactor test device, Kiwi-A. Studies on a zero power mock-up (Zepo-A) helped establish its design de… more
