Problems solved by technology
[0005] However, the above-mentioned existing technologies have at least the following defects: adding similar equipment will greatly increase the procurement cost of processing equipment, and it is difficult to control the procurement cycle, which will affect the use of the system; the difficulty of auxiliary equipment transformation will increase the storage pressure of system equipment space; system equipment The processing space is limited, which brings limitations to equipment design; human intervention will increase the accidental radiation risk of operating personnel
[0006] In view of this, it is necessary to provide a smartly structured nuclear power plant waste filter element transfer container to solve the problem of filter element jamming

Embodiment Construction
[0024] In order to make the purpose of the invention, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.
[0025] see figure 1 and figure 2 As shown, the nuclear power plant waste filter element transfer container of the present invention includes a container body 10 and an inner sleeve 20 with a tapered top opening. The inner sleeve 20 is coaxially arranged with the container body 10 and is at the same height as the container body 10. The top end of the barrel 20 is fixedly connected with the inner wall of the container body 10 .
[0026] see figure 1 As shown, the inner sleeve 20 includes a cone section cylinder 202 an...

The invention discloses a waste filter cartridge transfer container of a nuclear power plant comprising a container body and an inner sleeve having a tapered opening at the top end. The diameter D of the inner sleeve satisfies the formula: D1<D<=LsinAlpha + dcosAlpha, wherein D1 is a the maximum diameter of the filter cartridge, L is the length of the jam filter cartridge, d is the diameter of the jam filter cartridge, and alpha is the inclination angle formed by the minimum filter cartridge which does not appear in the jam condition and the inner wall of the container body. Compared with the prior art, the waste filter cartridge transfer container transfer container of the invention has the following advantages: the problem of radioactive filter cartridge jamming is solved, the exposure of the radioactive waste in the plant is avoided, the safe operation of the power station and the safety of the surrounding environment are guaranteed; without changing the equipment, implement is simple, loading of the nuclear power unit is not restricted, and economic cost of treatment is greatly reduced; technical vulnerabilities of improvements of 8TES system are effectively compensated, and the progress of nuclear power technology is promoted.
Description
technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a transfer container for nuclear power plant waste filter elements. Background technique [0002] At present, during the operation of nuclear power plants, the advanced high-density polyethylene high-integral container (HIC) barrel treatment process is usually used to directly fill and dehydrate radioactive waste (waste resin and waste filter element). The waste filter element filling process includes: the waste filter element falls into the waste filter element transfer container from the filter element descending channel, and then the transfer container is transported to the HIC barrel treatment process, and the waste filter element slides from the transfer container into the HIC barrel. [0003] The design of the filter element transfer container should not only realize the transfer of the four main filter elements of 6 inches, 8 inches, 12...
