It is an advantage of the invention that semi-buried type double-reactor nuclear island plant layout can reduce nuclear power plant cost, improve
Reactor anti-attack of terrorism ability, it is possible to resolve containment short-term and cooling down for a long time after multiple extreme accident superposition.
Accompanying drawing explanation
Fig. 1 is semi-buried type double heap nuclear island factory building plane graph provided by the present invention；
Fig. 2 is semi-buried type double heap nuclear island factory building profile provided by the present invention.
In figure, 1 reactor building, 2 reactors, 3 electrical buildings, 4 fuel Factory Buildings, 5 cores assist factory
Room, 6 containment steel domes, 7 ponds.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, semi-buried type double-reactor nuclear island plant layout it include that nuclear island factory building, nuclear island factory building include two
Individual reactor building 1, electrical building 3, fuel Factory Building 4 and nuclear auxiliary building 5, wherein, two reactors
Factory Building 1 lays respectively at the both sides of fuel Factory Building 4, and the side of two reactor buildings 1 and fuel Factory Building 4 is arranged
Having electrical building 3, opposite side is provided with nuclear auxiliary building 5, and fuel Factory Building 4 is arranged in nuclear island factory building central authorities,
Double heap common fuel Factory Buildings 4, share Factory Building and facility to greatest extent.
As in figure 2 it is shown, for improving reactor anti-attack of terrorism ability, contain the reaction of nuclear steam supply system
Heap Factory Building 1 half is embedded in underground, all includes a reactor in each reactor building 1, and reactor is installed
Below ground elevation, reactor building 1 is exposed to aerial parts by electrical building 3, fuel Factory Building 4 and core
Auxiliary plant 5 surrounds and protects；The containment steel dome 6 of reactor building 1 is submerged in pond, when
Reactor generation loss of-coolant accident (LOCA) or the multiple extreme accident such as main steam line rupture accident superposition station blackout
After, with natural principles such as conduction of heat, convection current and water evaporations, containment heat is passed to ultimate heat sink big
Gas.
With a specific embodiment, the present invention is further detailed below.The thermal power of double heaps is
500MW, reactor building internal diameter 28m, for improving reactor anti-attack of terrorism ability, contain reactor
Reactor building half be embedded in underground, reactor is positioned at below ground elevation 5m, and reactor building exposes
It is 22m in aerial parts height, electrical building, fuel Factory Building and nuclear auxiliary building surrounds and protect；
Fuel Factory Building is arranged in nuclear island factory building central authorities, double heap common fuel Factory Buildings, shares Factory Building to greatest extent and sets
Execute；As in figure 2 it is shown, the containment steel dome of reactor building is submerged in pond, the water loading amount in pond
It is about 1500m3.When reactor generation loss of-coolant accident (LOCA) or main steam line rupture accident superposition station blackout
After multiple extreme accident, with natural principles such as conduction of heat, convection current and water evaporations, containment heat is transmitted
To ultimate heat sink air.It floods the water yield can realize containment cooling up to more than 7 days.
The present invention can be used for advanced nuclear power heap-type, particularly the middle-size and small-size power reactor nuclear island factory based on heat supply
Room layout design, can improve safety and the economy of nuclear energy.
