摘要： A self-powered in-core neutron detector assembly in which a plurality of longitudinally extending self-powered detectors have neutron responsive active portions spaced along a longitudinal path. A low neutron absorptive extension extends from the active portions of the spaced active portions of the detectors in symmetrical longitudinal relationship with the spaced active detector portions of each succeeding detector. The detector extension terminates with the detector assembly to provide a uniform perturbation characteristic over the entire assembly length.

摘要： A method of fabricating a self-powered nuclear radiation detector assembly comprising a detector portion of accurately predetermined dimensions and a cable portion connected to the detector portion to carry the signal current which is generated in a radiation flux field to remote monitoring means. The detector portion consists of a radiation responsive elongated central emitter electrode which is insulated from a generally tubular sheath collector electrode. The emitter electrode and the signal cable center wire are electrically connected at one end and disposed within the collector electrode tubular sheath with compressible insulating means disposed between the wires and the tubular sheath. The above assembly is reduced in diameter while elongating the tubular sheath and the emitter wire and signal cable wire. The emitter wire is reduced to a predetermined desired diameter, and is trimmed to a predetermined length. An end cap is hermetically sealed to the tubular sheath at the extending end of the emitter with insulating means between the emitter end and the end cap.

摘要： An improved heater facsimile temperature detector (47) has an increased dynamic responsiveness in measuring temperature changes. The improved HFTD (47) reduces the amount of mass surrounding the thermocouple tip, thus, reducing the time lag caused by the intervening heating or cooling of this material before the temperature change can affect the thermocouple. The thermocouple (69) is welded to a body (59) extending beyond a machined flat (54) on the outer surface of an intermediate portion (49) of the HFTD. The body does not extend beyond the outer surface (51) of the intermediate portion.
