Abstract

The invention belongs to a nuclear island plant layout and particularly relates to a semi-buried type double-reactor nuclear island plant layout. The semi-buried type double-reactor nuclear island plant layout comprises reactor plants, an electric plant, a fuel plant and a nuclear auxiliary plant, wherein the two reactor plants are respectively located at the two sides of the fuel plant; the electric plant is arranged at one sides of the two reactor plants and the fuel plant; and the nuclear auxiliary plant is arranged at the other sides of the two reactor plants and the fuel plant. The semi-buried type double-reactor nuclear island plant layout has the advantages that the construction cost of nuclear power plants can be reduced, the terrorist attack resisting capability of reactors is improved and the problem that a safety shell is cooled for a short period or a long period after a plurality of extreme accidents are overlapped can be solved.

Description

A kind of half buried pair of core island factory building arranged

Technical field

The invention belongs to a kind of nuclear island factory building and arrange, be specifically related to a kind of half buried pair of core island factory building and arrange.

Background technology

More than common nuclear power plant's nuclear island factory building is above ground level quite the height, reactor building is exposed to single engine flivver that ground containment only can bear 1.5 tons of weights with the Maximum speed limit 360kmh shock that falls, and can't tackle the attack of terrorism of U.S. " 9.11 " and so on.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can improve the anti-attack of terrorism ability of reactor and cheap a kind of half buried pair of core island factory building arranged.

The present invention realizes like this, half buried pair of core island factory building, it comprises reactor building, electrical building, fuel factory building and nuclear auxiliary building, wherein, two reactor buildings lay respectively at the both sides of fuel factory building, one side of two reactor buildings and fuel factory building is provided with electrical building, and opposite side is provided with nuclear auxiliary building.

Described reactor building half be embedded in undergroundly, includes a reactor in each reactor building, and reactor is installed on below ground level.

The containment steel dome of described reactor building is submerged in pond.

Advantage of the present invention is that half buried pair of core island factory building arranged and can be reduced the nuclear power plant cost, improves the anti-attack of terrorism ability of reactor, can solve the rear containment short-term of multiple extreme accident stack and cooling for a long time.

The accompanying drawing explanation

Fig. 1 is half buried pair of core island factory building plan view provided by the present invention;

Fig. 2 is half buried pair of core island factory building sectional drawing provided by the present invention.

In figure, 1 reactor building, 2 reactors, 3 electrical buildings, 4 fuel factory buildings, 5 nuclear auxiliary buildings, 6 containment steel domes, 7 ponds.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

As shown in Figure 1, half buried pair of core island factory building arranges that it comprises nuclear island factory building, nuclear island factory building comprises two reactor buildings 1, electrical building 3, fuel factory building 4 and nuclear auxiliary building 5, wherein, two reactor buildings 1 lay respectively at the both sides of fuel factory building 4, and two reactor buildings 1 are provided with electrical building 3 with a side of fuel factory building 4, opposite side is provided with nuclear auxiliary building 5, fuel factory building 4 is arranged in nuclear island factory building central authorities, and two heap common fuel factory buildings 4 share factory building and facility to greatest extent.

As shown in Figure 2, for improving the anti-attack of terrorism ability of reactor, contain nuclear steam supply system reactor building 1 half be embedded in underground, include a reactor in each reactor building 1, reactor is installed on below ground level, and reactor building 1 is exposed to overground part and is surrounded and protected by electrical building 3, fuel factory building 4 and nuclear auxiliary building 5; The containment steel dome 6 of reactor building 1 is submerged in pond, after the multiple extreme accidents such as reactor generation loss of-coolant accident (LOCA) or main steam line rupture accident the station blackout that superposes, with natural principles such as heat conduction, convection current and water evaporations, the containment heat is passed to ultimate heat sink-atmosphere.

Below with a specific embodiment, the present invention is further detailed.The thermal power of two heaps is 500MW, reactor building internal diameter 28m, for improving the anti-attack of terrorism ability of reactor, the reactor building of containing reactor half be embedded in underground, reactor is positioned at the following 5m of ground level, it is 22m that reactor building is exposed to the overground part height, by electrical building, fuel factory building and nuclear auxiliary building, is surrounded and is protected; The fuel factory building is arranged in nuclear island factory building central authorities, and two heap common fuel factory buildings share factory building and facility to greatest extent; As shown in Figure 2, the water loading amount that the containment steel dome of reactor building is submerged in Zhong， pond, pond is about 1500m3.After the multiple extreme accidents such as reactor generation loss of-coolant accident (LOCA) or main steam line rupture accident the station blackout that superposes, with natural principles such as heat conduction, convection current and water evaporations, the containment heat is passed to ultimate heat sink-atmosphere.It floods the water yield can realize that containment is cooling and reach more than 7 days.

The present invention can be used for advanced nuclear power heap type, particularly take heat supply as main middle-size and small-size power reactor nuclear island factory building layout design, can improve safety and the economy of nuclear energy.
