Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0030] A preferred embodiment of the present invention provides a connection device for a neutron flux measuring instrument outside the nuclear power plant, such as figure 2 As shown, the measuring device includes two or more sequentially connected sleeves 1, the sleeve 1 includes a connection section arranged at the end and an accommodating section for setting a neutron flux detector. The flux detector is fixedly installed in the accommodating section.
[0031] Further, the measuring device also includes a rotating connector 2 respectively arranged between every two adjacent sleeves 1, and the a...

The invention discloses a connecting device of a nuclear power plant out-of-core neutron flux measurer and a mounting method of the connecting device. The connecting device of the nuclear power plant out-of-core neutron flux measurer is provided with at least two sleeves which are connected sequentially, and rotating connecting pieces, two adjacent sleeves are connected through the rotating connecting pieces, the sleeves comprise connecting sections arranged at the ends and containing sections for containing neutron flux detectors, the neutron flux detectors are fixedly arranged in the containing sections, the rotating connecting pieces are detachably and fixedly connected with the connecting sections of the sleeves, and every two adjacent sleeves can relatively rotate. According to the connecting device of the nuclear power plant out-of-core neutron flux measurer and the mounting method of the device, the sleeves can relatively rotate under action of external force, and therefore a measuring device is not prone to being broken and damaged, when one neutron flux detector fails, a user only needs to take down the faulted sleeve to replace the faulted sleeve with a new one, or the faulted sleeve is opened, then, a new neutron flux detector is contained in the sleeve, and a whole detection device does not need to be changed.
Description
technical field [0001] The invention relates to the field of nuclear power, in particular to a connection device and an installation method for a neutron flux measuring device outside a nuclear power plant. Background technique [0002] The neutron flux measurement equipment outside the reactor of a million-kilowatt nuclear power plant mainly uses measurement equipment with overlapping ranges to measure the neutron flux in different reactor operating stages (start-up, rising power, and full power, etc.). The neutron flux measurement equipment outside the reactor generally adopts three different ranges of measurement equipment, which are source range, intermediate range and power range neutron flux measurement equipment. The extra-core neutron flux detectors with three ranges must be placed at a fixed position with the entire height of the active section of the core (axial direction); at the same time, by installing push-pull devices in the radial direction (radial direction)...
