摘要： A coaxial electrical signal cable is inherently compensated for gamma flux induced currents by the use of selected alloys for the central conductive wire. The central conductive wire alloy comprises a first metal which interacts with the gamma flux to produce a negative current contribution between the central conductive wire and the conductive sheath, and a second metal which interacts with the gamma flux to produce a positive current contribution, which in combination with the signal produced in the conductive sheath results in a null gamma induced current for the cable.

摘要： A self-powered neutron detector in which two electrically isolated emitter electrodes are provided. The emitters are formed of different materials having differing responses to thermal and epithermal neutron flux. The separate signals generated between the separate emitters and a common collector electrode are used to determine the respective thermal and epithermal neutron fluxes for a more accurate flux mapping of the reactor core.

摘要： Seismic restraint means are provided for mounting an elongated, generally cylindrical nuclear radiation detector within a tubular thimble. The restraint means permits longitudinal movement of the restraint means and the radiation detector into and out of the thimble. The restraint means includes spring bias means and thimble constant means whereby the contact means engage the thimble with a constant predetermined force which minimizes seismic vibration action on the radiation detector.
