A -- COINCIDENT GAMMA-NEUTRON ASSAY TECHNIQUE Contact Dr. Michael E. McLLwain Lockheed Idaho Technologies Company (LITCO), P.O. Box 1625, Idaho Falls, ID 83415-3805. U.S. Patent No. 5,378,895. Contact Dr. Michael E. McLLwain. Potential Licensing Opportunity with LITCO, the prime operating contractor of the Department of Energy at the Idaho National Engineering Laboratory (INEL). LITCO has developed and patented the following technology: Coincident Gamma-Neutron Assay Technique (GNAT), that measures the isotopic ratios of special nuclear material, is available for licensing. The method uses a totally new, nondestructive approach to identifying the specific fissioning isotopes. Currently used safeguard instruments for the assay of fissionable materials, rely on detection of low-energy gamma-rays having low penetrating power or the measurement of neutron multiplication requiring a complex detector geometry. The INEL GNAT system overcomes the deficiencies of standard safeguard methods with an entirely new approach based on the understanding of and using the physics of the fission process. In the fission process many different isotopes are produced, with these products called ``fission fragments.'' The important fact associated with these fragments is that for every fission, a pair of fragments is produced. GNAT can identify the element that is fission because the sum of the fission pair protons is equal to the number of protons in the nucleus that fissioned. The conversion property does not hold for the combined mass of the two fragments, which is generally less than the initial mass of the fissioning isotopes. By determining which different isotopes of the light-mass fragments are present using the coincidence relationships, and in what ratio, the isotopic ratios of the fissioning material can be determined. LITCO is soliciting a written indication of interest from industry parties who would consider entering into a licensing agreement for the purpose of commercializing this technology. No later than 30 days following posting of this announcement, interested industry parties should send a description of their company, their research capability, and the potential application of the subject technology to: Dr. Michael E. McLLwain, Technology Transfer Office, LITCO, P.O. Box 1625, Idaho Falls, ID. 83415-3805. (265)
