In existing Class PWR Plants, fuel transfer device takes the mode of being transported one by one by fuel assembly usually.
In the design of nuclear power station, higher available rate also becomes the important indicator of advanced nuclear power technology, and one of approach of technological improvement is exactly that shortening is as far as possible reloaded the time.Along with the raising of nuclear power station design power, stage of reloading needs the fuel assembly quantity changed also significantly to increase, time of reloading extends thereupon, no matter be economy of power plant, or the irradiation dose accumulation of site operation personnel, all be encountered by new problem, need research and development nuclear fuel assembly transport equipment more efficiently.
Summary of the invention
For the defect existed in prior art, the object of this invention is to provide a kind of bogey for transporting irradiated fuel assembly, this bogey structure is simple, the mechanical strength of equipment and the requirement of cooling power can be met simultaneously, adopt this carrying to fill and can improve fuel transport efficacy, improve economy of power plant, reduce staff's occupational radiation dose.
For reaching above object, the technical solution used in the present invention is: a kind of bogey for transporting irradiated fuel assembly, being assembled into xsect by three identical carriers is triangle disposition, each carrier is the cuboid of both ends open, four panels of carrier has along its length the equally distributed through hole of two rows.
Further, through hole is Long Circle hole, and on the veneer of carrier, the circulation area summation of through hole is no more than 20% of veneer area.
Further, the through hole between two exhausting holes adjacent on four panels of carrier, adjacent panels and the through hole relatively between plate all arrange in the mode be staggered.
Further again, the surface of contact of the top board of the side plate of the carrier on the upper strata of described bogey and each carrier of lower floor is on the top board of the carrier of lower floor between two exhausting holes.
Further, the side plate of the carrier on the upper strata of described bogey is connected by multiple L-type support member with the top board of each carrier of lower floor, and multiple L-type support member is evenly distributed and evenly distributed in the mode of the through hole that staggers along the length direction of carrier.
Further, inside each top board of carrier, center line is along its length provided with positioning strip.
Further, two side plates of carrier have the upper edge higher than top board and the lower edge lower than base plate respectively, and the height of upper edge is lower than the height of lower edge.
Further, the lower edge of two side plates of carrier has corresponding breach.
The present invention is on the basis that mechanical analysis and Flow and Temperature are analyzed, by carrying out innovative design to carrier, the technological process of reloading must transported one by one under existing weaponry and equipment condition is made to change the operating procedure simultaneously can transporting multiple assembly more efficiently into, thus be that the work efficiency improved during nuclear power plant reloads provides possible condition, simultaneously in order to solve the cooling problem of the fuel assembly faced when multiple assembly is transported simultaneously, the present invention is by the carrier of design four sides perforate, arrange lead to the hole site with being staggered, and positioning strip is set inside carrier top board and excavates some breach in the bottom of carrier side plate and form a series of technological means such as permeable groove, enhance the flowing of chilled water in carrier inside, thus a kind of and the distinct bogey of existing weaponry and equipment are provided, both the mechanical strength of equipment and the requirement of cooling power can have been met, on the other hand also for improving fuel transport efficacy, shorten and improve economy of power plant, reduce staff's occupational radiation dose and provide equipment Safeguard.

Fig. 1 is the structural representation of a kind of bogey for transporting irradiated fuel assembly provided by the invention;
Fig. 2 is carrier local unit structural representation in Fig. 1;
Fig. 3 is that in Fig. 1, carrier has loaded the local unit structural representation after irradiated fuel assembly.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, a kind of bogey for transporting irradiated fuel assembly provided by the present invention, being assembled into xsect by three identical carriers 1 is triangle disposition, between any two there is gap, each carrier 1 is the cuboid of both ends open, four panels of carrier 1 has along its length the equally distributed through hole 2 of two rows.
Through hole 2 can be Long Circle hole.On the veneer of carrier 1, the circulation area summation of through hole 2 is no more than 20% of veneer area.
Preferably, the through hole 2 between two exhausting holes 2 adjacent on four panels of carrier 1, adjacent panels and the through hole 2 relatively between plate all arrange in the mode be staggered.Can make like this on the cross section of carrier 1 optional position, have on a single plate and only have one section of opening, thus ensure that the mechanical strength of equipment, the flowing simultaneously can strengthening carrier 1 inside is mixed, make cooling effect everywhere relatively uniform, can avoid occurring large stretch of flow dead.More preferably, the surface of contact of the top board 1-1 of the side plate 1-2 of the carrier 1 on bogey upper strata and each carrier 1 of lower floor is on the top board 1-1 of the carrier 1 of lower floor between two exhausting holes 2, avoid the carrier blocking flow channel on upper strata, reduce flowing property.
In the present invention, the side plate 1-2 of the carrier 1 on the upper strata of bogey is connected with bolt by multiple L-type support member 2 with the top board of each carrier 1 of lower floor, and multiple L-type support member 2 is evenly distributed in the mode of the through hole 2 of each carrier 1 that staggers along the length direction of carrier 1.L shape back up pad 3 and bolt thereof, can ensure the firm connection of whole assembly, meet the rigidity requirement of carrier entirety, and make to keep certain gap between adjacent carrier 1.
In addition, as shown in Figure 3, inside each top board 1-1 of carrier 1, center line along its length can arrange positioning strip 6, for to the accurate location in nuclear fuel assembly carrier 1 during fuel investment assembly 5, positioning strip 6 also can form hydrophobic layer inside the top board 1-1 of carrier 1 and between fuel assembly 5 simultaneously, thus promoting the discharge of hot water, the cooling preventing local weakens.
In addition, as shown in Figure 2, two side plate 1-2 of carrier 1 have respectively higher than the upper edge of top board 1-1 and the lower edge lower than base plate 1-3, and the height of upper edge is lower than the height of lower edge.Adopt this structure, naturally leave gap between the upper edge of the base plate 1-3 of the carrier 1 on upper strata and the carrier 1 of lower floor, in case there is flow dead.
Preferably, the lower edge of two side plate 1-2 of each carrier 1 has corresponding breach 4, these breach 4 define some permeable grooves in compartment of terrain below the base plate 1-3 height of carrier 1, the through hole 2 that cold water for carrier 1 outside enters carrier 1 base plate 1-3 place provides circulation path, thus promotes the cooling of the fuel assembly 5 at bogey bottom position place.
Structure of the present invention is not limited to the embodiment described in embodiment, and those skilled in the art's technical scheme according to the present invention draws and other embodiment belongs to technological innovation scope of the present invention equally.
