    摘要： A fuel ball detecting method and system with a self-diagnosis function are provided. The method includes: exciting a first detecting coil and a second detecting coil of a fuel ball sensor disposed outside a pipeline; obtaining a first voltage signal U1 from the first detecting coil and a second voltage signal U2 from the second detecting coil; processing U1 and U2 by differential amplification, band pass filtering, phase sensitive detection and low pass filtering by a signal processor to obtain a fuel ball waveform signal U0; determining whether the fuel ball passes the pipeline according to U0 by a single chip microcomputer; determining whether the first and the second detecting coils, the signal processor and the single chip microcomputer work normally; outputting a result showing whether the fuel ball passes the pipeline, when the first and the second detecting coils, the signal processor and the single chip microcomputer work normally.

    摘要： The invention provides a regulating apparatus (10) for regulating the movement of spherical elements from one location, typically from a container (14), to another. The apparatus (10) includes a cylindrical tubular member (18) and a feed head (20) mounted in the spherical tubular member (18) so that it is rotatable relative thereto about an axis of rotation (22). A feed passage (32) opens upwardly out of a radially outer edge portion of the feed head (20). As the feed head (20) rotates, spherical elements enter the feed passage (32) and are discharged therefrom.

    摘要： The invention discloses a serial high-temperature gas-cooled reactor nuclear energy system and an operating method thereof. The serial high-temperature gas-cooled reactor nuclear energy system includes a plurality of high-temperature gas-cooled reactors and a serial gas-cooled reactor. The high-temperature gas-cooled reactor includes a first reactor pressure vessel comprising a first reaction chamber for accommodating the first fuel element; a second reactor pressure vessel comprising a second reaction chamber interconnected with the first reaction chamber, allowing the first spent fuel in the first reaction chamber to enter the second reaction chamber. The system of the present invention allows the spent fuel discharged from the high-temperature gas-cooled reactor to be directly reused as fuel for the serial gas-cooled reactor, thereby improving the utilization rate of nuclear fuel and reducing the cost of gas-cooled reactors, which is conducive to the promotion of industrialized application of high-temperature gas-cooled reactors.
