Feasibility Studies of a Carbon/Oxygen Logging Tool for Evaluating the CO sub 2 Content of the Medium in Nuclear Device Containment

摘要

The feasibility of using oil-well bore-hole logging techniques for assaying the carbonate content of a potential shot site has been investigated. The procedure makes use of the detection of the 4439-keV gamma ray of carbon and the 6130-keV gamma ray of oxygen produced by the inelastic scattering of 14-MeV neutrons in the bore-hole medium. For the needs of the containment program, a sensitivity of detection of CO sub 2 to less than or equal to 0.02 weight fraction must be achieved. Laboratory measurements indicate that only with considerable development effort could a tool be made that would come close to achieving this goal. (ERA citation 09:010635)
