摘要： A long-lifespan in-core instrument having an extended lifespan due to an enhanced combustion lifespan of an emitter according to the present invention comprises: a central tube; an outer sheath tube distanced from the outer circumferential surface of the central tube; self-powered neutron detectors placed between the central tube and outer sheath tube, and each comprising an emitter of a material having a reaction cross section with neutron that is comparatively smaller than that of rhodium; a background detector for compensating for the background noise signal; core exit thermocouples for detecting the core exit temperature; and filler wires filling in the space between the self-powered neutron detectors, background detector and core exit thermocouples, and as such, the present invention can markedly reduce the amount of spent in-core instrument waste, which is high-level radioactive material, and thus can contribute in securing a utility space for the high-level waste material, as well as in reducing radiation exposure of the nuclear power plant personnel.

摘要： The apparatus includes two or more electrical conductors, one or more signal devices, an analyzer and a time-domain reflectometer. The one or more signal devices may be adapted to apply one or more signals to the two or more electrical conductors and receive one or more signals from the two or more electrical conductors. The analyzer is adapted to determine power level in the nuclear reactor using at least one of the applied signals and at least one of the received signals. The method of determining power level in a nuclear reactor includes: measuring impedance values of two or more electrical conductors disposed in the nuclear reactor and using the measured impedance values to determine the power level.

摘要： A neutron detection system may include a neutron detection device located outside of a reactor vessel. The neutron detection device may be configured to detect neutrons generated within the reactor vessel. A containment region located intermediate the reactor vessel and a containment vessel may be configured to house a containment medium. A neutron path device may be at least partially located between the reactor vessel and the containment vessel, and the neutron path device may be configured to provide a neutron path to the neutron detection device through a neutron path medium contained within the neutron path device. A neutron attenuation coefficient associated with the neutron path medium may be smaller than a neutron attenuation coefficient associated with the containment medium.
