Abstract

A device for accurately measuring the mass of /sup 240/Pu and /sup 239/Pu in a sample having arbitrary moderation and mixed with various contaminants. The device utilizes a thermal neutron well counter which has two concentric rings of neutron detectors separated by a moderating material surrounding the well. Neutron spectroscopic information derived by the two rings of detectors is used to measure the quantity of /sup 239/Pu and /sup 240/Pu in device which corrects for background radiation, deadtime losses of the detector and electronics and various other constants of the system.

Direct fissile assay of enriched uranium using random self-interrogation and neutron coincidence response

Patent Menlove, H.O.; Stewart, J.E.

An apparatus is described for determining the quantity of fissile nuclides contained in a sample having substantially one type of fissile nuclide in the presence of nuclides which spontaneously generate alpha particles and nuclides which interact with alpha particles to produce neutrons, by random self-interrogation and neutron coincidence response. The apparatus consists of: (a) neutron detectors disposed in a substantially cylindrical manner around the cylindrical sample under investigation so that a fraction of neutrons escaping from the cylindrical sample as a result of fission processes in the fissile nuclides, (..cap alpha..,n) processes in other nuclides, and from less important sourcesmore »« less
Direct fissile assay of enriched uranium using random self-interrogation and neutron coincidence response

Patent Menlove, H.O.; Stewart, J.E.

Apparatus and method for the direct, nondestructive evaluation of the /sup 235/U nuclide content of samples containing UF/sub 6/, UF/sub 4/, or UO/sub 2/ utilizing the passive neutron self-interrogation of the sample resulting from the intrinsic production of neutrons therein. The ratio of the emitted neutron coincidence count rate to the total emitted neutron count rate is determined and yields a measure of the bulk fissile mass. The accuracy of the method is 6.8% (1sigma) for cylinders containing UF/sub 6/ with enrichments ranging from 6% to 98% with measurement times varying from 3-6 min. The samples contained from below 1more »« less
Method for determining random coincidence count rate in a scintillation counter utilizing the coincidence technique

Patent Horrocks, D.L.

A method is described for the reliable determination of a random coincidence count attributable to chance coincidences of single-photon events which are each detected in only a single detector of a scintillation counter utilizing two detectors in a coincidence counting technique. The method includes the steps of measuring a coincidence count rate as indicated by essentially coincident output pulses from the detectors, measuring a single photon count rate as indicated by output pulses from both of the detectors, whether coincident or not, and determining a random coincidence count rate from the difference between the single photon count rate and themore »« less
Method and apparstus for determining random coincidence count rate in a scintillation counter utilizing the coincidence technique

Patent Horrocks, D.L.

A method and apparatus for the reliable determination of a random coincidence count attributable to chance coincidences of single-photon events which are each detected in only a single detector of a scintillation counter utilizing two detectors in a coincidence counting technique are described. A firstdelay device is employed to delay output pulses from one detector, and then the delayed signal is compared with the undelayed signal from the other detector in a coincidence circuit, to obtain an approximate random coincidence count. The output of the coincidence circuit is applied to an anti-coincidence circuit, where it is corrected by elimination ofmore »« less
Multiple channel programmable coincidence counter

Patent Arnone, G.J.

This patent describes a programmable digital coincidence counter having multiple channels and featuring minimal dead time. Neutron detectors supply electrical pulses to a synchronizing circuit which in turn inputs derandomized pulses to an adding circuit. A random access memory circuit connected as a programmable length shift register receives and shifts the sum of the pulses, and outputs to a serializer. A counter is input by the adding circuit and downcounted by the seralizer, one pulse at a time. The decoded contents of the counter after each decrement is output to scalers.
