The following will be combined with... Figure 1-4 The structure of the uranium hexafluoride leakage experimental device based on a polygonal prism according to the embodiments of this application will be described in detail.

[0062] In one exemplary embodiment, the uranium hexafluoride leakage experimental apparatus based on a polygonal prism of this application is used to simulate and observe the basic parameters during uranium hexafluoride leakage. By monitoring and sampling, the chemical components of the uranium hexafluoride leakage and the physical state of the chemical reaction products are obtained, providing a basis for nuclear and radiation safety analysis of uranium hexafluoride leakage accidents.

[0064] In one exemplary embodiment, the number of lateral edges of the polygonal prism 101 is a positive integer multiple of 8, which can be understood as the polygonal prism 101 being an octagonal prism, a hexagonal prism, etc.

[0065] In one exemplary embodiment, the polygonal prism 101 is a regular prism, that is, the side edges of the polygonal prism 101 are perpendicular to the end face and the end face is a regular polygon.

[0066] In one exemplary embodiment, the polygonal prism 101 is made of a transparent hydrophobic material.

[0067] In one exemplary embodiment, the polygonal prism 101 is made of transparent acrylic material, or transparent polysulfone, or transparent polytetrafluoroethylene.

[0068] In one exemplary embodiment, the polygonal prism 101 is made transparent to facilitate observation and measurement.

[0069] In one exemplary embodiment, the side of the polygonal prism 101 is provided with an observation surface 106, a sampling surface 107, a particle size measurement laser emitting surface 109, and a particle size measurement laser receiving surface 108.

[0070] In one exemplary embodiment, the side of the polygonal prism 101 includes a particle size measurement laser emitting surface 109 and a particle size measurement laser receiving surface 108; it can be understood that when the polygonal prism 101 is an octagonal prism, one side is the particle size measurement laser emitting surface 109 and the other side is the particle size measurement laser receiving surface 108.

[0071] In one exemplary embodiment, the particle size measuring laser emitting surface 109 and the particle size measuring laser receiving surface 108 are arranged facing each other, and the particle size measuring laser emitting surface 109 and the particle size measuring laser receiving surface 108 are parallel to each other, such as... Figure 3 As shown.

[0072] In one exemplary embodiment, a laser emission interface is also provided on the particle size measurement laser receiving surface 108, such as... Figure 3 As shown.

[0073] In one exemplary embodiment, the laser beam emitted by the laser emission interface is parallel to the laser beam emitted by the particle size measurement laser emission surface 109, such as... Figure 3 As shown.

[0074] In one exemplary embodiment, a particle size measurement receiving position is also provided on the particle size measurement laser receiving surface 108.

[0075] In one exemplary embodiment, the particle size measurement receiving position is used to receive the laser beam emitted from the particle size measurement laser emitting surface 109.

[0076] In one exemplary embodiment, the observation surface 106 is perpendicular to the particle size measurement laser receiving surface 108.

[0077] In one exemplary embodiment, the sampling surface 107 is disposed between the observation surface 106 and the particle size measurement laser receiving surface 108.

[0078] In one exemplary embodiment, the sampling surface 107 is disposed between the observation surface 106 and the particle size measurement laser emitting surface 109.

[0079] In an exemplary embodiment, taking the polygonal prism 101 as an octagonal prism as an example, two observation surfaces 106 and four sampling surfaces 107 are provided, and the observation surfaces 106 and the sampling surfaces 107 are arranged adjacent to each other.

[0080] In one exemplary embodiment, the number of sampling faces 107 is half the number of side edges of the polygonal prism 101, that is, when the polygonal prism 101 is an octagonal prism, there are four sampling faces 107.

[0081] In one exemplary embodiment, the sampling surface 107 is provided with a plurality of sampling interfaces 105, for example, each sampling surface is provided with three equally spaced sampling interfaces 105, such as... Figure 1 and Figure 2 As shown.

[0082] In one exemplary embodiment, the number of observation surfaces 106 is less than the number of sampling surfaces 107.

[0083] In one exemplary embodiment, a uranium hexafluoride inlet is provided on one end face of the polygonal prism 101, for example, the uranium hexafluoride inlet is provided on the right end face of the polygonal prism 101.

[0084] In one exemplary embodiment, a uranium hexafluoride release pipeline 102 is connected to the uranium hexafluoride inlet.

[0085] In one exemplary embodiment, the uranium hexafluoride inlet is in communication with the chamber.

[0086] In one exemplary embodiment, a mixed gas outlet is provided on the end face opposite to the end face where the uranium hexafluoride inlet is located. For example, if the uranium hexafluoride inlet is located on the right end face, then the mixed gas outlet is located on the left end face.

[0087] In one exemplary embodiment, the outlet of the mixed gas is connected to a condensation system and a scrubbing tower filtration system as needed, and the gas is discharged after being filtered to meet the standards.

[0088] In one exemplary embodiment, the uranium hexafluoride leakage experimental apparatus based on a polygonal prism of this application further includes a water vapor pipeline 104.

[0089] In one exemplary embodiment, the steam pipe 104 is connected to the uranium hexafluoride inlet on the same end face; that is, when the uranium hexafluoride inlet is located on the right end face of the polygonal prism 101, the right end face is also connected to the steam pipe 104.

[0090] In one exemplary embodiment, the steam pipe 104 is in communication with the chamber.

[0091] In one exemplary embodiment, the axis of the uranium hexafluoride release pipeline 102 coincides with the axis of the polygonal prism 101. The axis coincidence is set to provide optimal space for the subsequent reaction of uranium hexafluoride and to avoid the uranium hexafluoride directly adhering to the side wall when it is set on the side, which would affect the reaction effect.

[0092] In one exemplary embodiment, the steam pipe 104 is connected to the right end face of the polygonal prism 101 through the steam pipe outlet 201.

[0093] In one exemplary embodiment, the steam pipe outlet 201 is fitted onto the uranium hexafluoride inlet.

[0094] In one exemplary embodiment, the axis of the steam pipe outlet 201 coincides with the axis of the uranium hexafluoride inlet, a design that allows for a more complete reaction between uranium hexafluoride and water.

[0095] In one exemplary embodiment, a heating layer 202 is also provided on the outer layer of the uranium hexafluoride release pipeline 102.

[0096] In one exemplary embodiment, the heating layer 202 is used to heat the uranium hexafluoride in the uranium hexafluoride release line 102 to the triple point temperature.

[0097] In one exemplary embodiment, the triple point temperature of uranium hexafluoride is 64°C.

[0098] In one exemplary embodiment, on the right end face of the polygonal prism 101, a heating layer 202 is fitted over the outer layer of the uranium hexafluoride release pipe, and a steam pipe outlet 201 is fitted over the outer layer of the heating layer 202.

[0099] In one exemplary embodiment, the steam pipe 104 includes a U-shaped pipe, which can be understood as the steam pipe 104 being provided with a U-shaped pipe. As needed, there may be one or more U-shaped pipes.

[0100] In one exemplary embodiment, the U-shaped tube design is intended to prevent uranium hexafluoride, after reacting with water vapor or before reacting, from entering the humidifier 103 along the water vapor pipe 104 and damaging it. Because of the U-shaped tube design, a certain amount of liquid water accumulates at the U-shaped tube, trapping any uranium hexafluoride that has entered the water vapor pipe and preventing further intrusion into the humidifier 103.

[0101] In one exemplary embodiment, a humidification device 103 is connected to the end of the water vapor pipe 104.

[0102] In one exemplary embodiment, the humidifier 103 is used to provide water vapor to the water vapor pipeline 104. As needed, the humidifier 103 heats the water inside to turn it into water vapor and then provides water vapor to the water vapor pipeline 104.

[0103] In one exemplary embodiment, the edge length of the polygonal prism 101 is, for example, 150 mm.

[0104] In one exemplary embodiment, when uranium hexafluoride gas in the uranium hexafluoride release pipe and water vapor in the water vapor pipe 104 simultaneously enter the chamber of the polygonal prism 101, the PIV measurement system monitors factors including temperature, humidity, pressure, flow field, and hydrogen fluoride concentration.

[0105] In one exemplary embodiment, a PIV measurement system, namely, a particle image velocity measurement (PIV) system.

[0106] In one exemplary implementation, such as Figure 3 As shown, taking the octagonal prism 101 as an example, the four sides of the octagonal prism are sampling surfaces 107, and the four sampling surfaces 107 are not adjacent to each other. Each sampling surface 107 is provided with a sampling interface 105. Two of the remaining four sides are observation surfaces 106, which are arranged opposite each other. The remaining two sides are the particle size measurement laser emitting surface 109 and the particle size measurement laser receiving surface 108. The observation surface 106 is used to observe the state of uranium hexafluoride reacting with water vapor under laser irradiation. The design of the observation surface 106 being perpendicular to the laser emission direction is to better observe the effect after laser irradiation.

[0107] In one exemplary embodiment, the laser emission interface is preferably located at the geometric center of the particle size measurement laser receiving surface 108, and the observation position on the observation surface 106 corresponds to the position of the laser emission interface.

[0108] In one exemplary embodiment, the observation position on the observation surface 106 corresponds to the position of the laser emission interface. This can be understood as the laser emission interface and the observation position being located on the same surface being perpendicular to the central axis of the polygonal prism 101.

[0109] In one exemplary embodiment, when the PIV measurement system is in use, the preferred particle size measurement laser emission line is arranged parallel to the laser emission line of the PIV measurement system; this can be understood as the particle size measurement position of the particle size measurement laser emission line on the particle size measurement laser emission surface 109, such as... Figure 3 As shown, the laser emission line of the PIV measurement system operates at the laser emission interface of the particle size measurement laser receiving surface 108 in a direction perpendicular to the particle size measurement laser emission surface 109.

[0110] In one exemplary embodiment, the sides of the polygonal prism 101 described in this embodiment are all surfaces formed between adjacent side edges.

[0111] While the embodiments disclosed in this invention are as described above, they are merely illustrative of the embodiments to facilitate understanding of the invention and are not intended to limit the invention. Any person skilled in the art to which this invention pertains may make any modifications and variations in the form and details of the implementation without departing from the spirit and scope disclosed herein; however, the scope of patent protection for this invention shall still be determined by the scope defined in the appended claims.
