And the weight of cooling agent is big, when reactor core reacts, amount of heat is released, the temperature and pressure in pressure vessel are all very high, therefore
Requirement to pressure vessel is very high.
The content of the invention
In view of this, the present invention is directed to propose a kind of fast core pressure vessel of lead bismuth, can be by supporting part and seal pressure
Partial is separated, and pressure is shared respectively, contributes to load-bearing more stable, and sealing effectiveness is more preferable, and installation and cooling reactor core are more square
Just.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of fast core pressure vessel of lead bismuth, including vessel shell, the upper end of the vessel shell is load-bearing end,
Also include the sealed end on the inside of the load-bearing end, the sealed end is vertically welded in the pressure by y-type structure branch point
On force container housing, the y-type structure branch point of Y types is located between the sealed end and the load-bearing end, and the load-bearing
End is higher than the sealed end.
Further, the upper surface at the load-bearing end is evenly distributed with multiple bolts hole, and all of bolt hole is surrounded
Cast.
Further, the upper surface of the sealed end is evenly distributed with multiple screwed holes and o-ring groove, all of spiral shell
Pit surrounds cast.
Further, the inside of the vessel shell surrounds inner chamber, and the bottom of the inner chamber is welded with assignment of traffic
Ring flat-plate, the upper end of the assignment of traffic ring flat-plate is provided with the cover plate for fixed nuclear core position, the side wall of the assignment of traffic ring flat-plate
It is provided with flow distributing hole.
Further, the vessel shell and the load-bearing end are made up of same sheet material.
Relative to prior art, the fast core pressure vessel of lead bismuth of the present invention has the advantage that：
Sealed end is vertically welded on vessel shell by y-type structure branch point, and load-bearing end and sealed end pass through Y types
Structure branch point is separated, and allows the part of load-bearing end institute load-bearing and the part of sealed end of vessel shell to separate, and is undertaken respectively
Partial function, can make load-bearing bottom bearing more stable, allow sealed end sealing effectiveness more preferably, and inner seal end is than outside load-bearing end highly
On have certain drop, certain space can be reserved in pressure shell body for installing lead bismuth fast reactor other components, and reduce
The height of reactor core.An assignment of traffic ring flat-plate is welded in container intracavity bottom, for flowing the liquid such as the cooling agent in container
Get up and distribute flow, preferably to cool down reactor core.

Concrete meaning in the present invention.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1, 2, the upper end of vessel shell 9 uses unique y-type structure, from y-type structure branch point 6 up
It is divided into load-bearing end 1 and sealed end 2, partial function is undertaken respectively, the load of load-bearing end 1 can be made more stable, allows the sealing effectiveness of sealed end 2
More preferably.There are 44 bolts hole 3 that a circle is uniform on load-bearing end 1, be bolted on the individual barrel structure of outside of containers.
There are two o-ring grooves 4 and to enclose 48 uniform screwed holes 5 on sealed end 2, can cross bolt and o-ring will seal
