Detailed Description
The invention is further described with reference to specific embodiments and drawings attached to the description.
An exemplary novel nuclear island non-seismic auxiliary plant layout structure of the invention is shown in fig. 1, and the layout structure is used for arranging independent non-seismic auxiliary plants in a nuclear island plant group of a nuclear power plant for arranging non-safety-level and non-seismic items in a nuclear island. The non-anti-seismic auxiliary plant is arranged close to the fuel plant and the auxiliary plant, and has a four-layer structure which is a first underground layer, a first overground layer, a second overground layer and a third overground layer from bottom to top. It adopts a novel frame structure, and belongs to non-nuclear grade anti-seismic structures.
The internal underground layer arrangement structure of the auxiliary plant is shown in fig. 2, a non-safety-level non-seismic demineralized water system 1 is arranged on one side, close to a fuel plant, of the underground layer of the auxiliary plant, and demineralized water is conveniently provided for each user in a nuclear island plant; the non-safety non-shock-resistant waste liquid receiving system 2 is arranged on one side, close to the auxiliary plant, of the underground layer of the auxiliary plant and used for collecting waste liquid in the nuclear island plant. The underground layer of the auxiliary factory building is communicated with the underground layer of the auxiliary factory building and belongs to a control area.
The ground floor arrangement structure in the auxiliary factory building is shown in fig. 3, a sanitary access 3 is arranged on the ground floor in the auxiliary factory building, and workers can directly enter the auxiliary factory building through the sanitary access 3 and then enter the control areas of other factory buildings. The workers entering the nuclear island control area can enter the sanitary access 3 of the auxiliary factory building from the overground layer of the auxiliary factory building and exit the nuclear island from the access door.
The two-layer and three-layer arrangement structure on the ground inside the auxiliary factory building is respectively shown in fig. 4 and 5, the non-safety non-anti-seismic fuel factory air supply system 4 is arranged on the two-layer on the ground of the auxiliary factory building and close to one side of the fuel factory building, and the fuel factory air exhaust system 8 is arranged on the three-layer on the ground of the auxiliary factory building and close to one side of the fuel factory building.
The arrangement scheme can effectively meet the air supply and exhaust requirements of the fuel plant and can effectively reduce the volume of the fuel plant.
And the non-safety non-shock-resistant auxiliary plant air supply system 5 and the auxiliary plant exhaust system 6 are both arranged on the two-layer overground part of the auxiliary plant close to one side of the auxiliary plant. The specific relative arrangement position is not limited, for example, the air supply system 4 of the fuel plant and the air supply system 5 of the auxiliary plant can be arranged at one side close to the auxiliary plant, and the air exhaust system 6 of the auxiliary plant can be arranged opposite to the air supply system 5 of the auxiliary plant, and the middle of the air exhaust system is separated by a passageway. The air supply and exhaust requirements of the auxiliary plant can be effectively met by the arrangement scheme, and the volume of the auxiliary plant can be effectively reduced.
The non-safety-level non-seismic nuclear island chilled water system 9 is arranged on one side, close to the auxiliary plant, of the three layers of the auxiliary plant ground. The arrangement method is convenient for providing the nuclear island chilled water for each user in the nuclear island, and can effectively reduce the volume of the auxiliary plant on the premise of meeting the process requirements.
The electrical factory building has the advantages that items in the original electrical factory building are concentrated, the quantity of cables is large, and if all the systems are arranged in the electrical factory building, the electrical factory building is large in size and high in ventilation and fire fighting pressure. Through the analysis of the items in the original electric factory building, partial non-earthquake-resistant electric instrument equipment exists in the factory building, and users of the electric instrument equipment are concentrated in an auxiliary factory building and an auxiliary factory building. The invention moves the part of items into an auxiliary factory building to establish a sub-load center 7 of the nuclear island electric instrument.
The nuclear island electrical instrument sub-load center 7 is arranged on the second floor and the third floor of the auxiliary factory building, and the sub-load center 7 comprises non-safe non-shock-resistant 380V low-voltage reliable power distribution system equipment serving the fuel factory building and the auxiliary factory building, a non-safe direct current and UPS power distribution system, a non-safe instrument control cabinet and 380V low-voltage normal power distribution system equipment. The specific positions of all the devices in the sub-load center 7 of the nuclear island electrical instrument can be arranged according to actual conditions.
According to the novel nuclear island non-seismic auxiliary plant layout structure provided by the invention, seismic items and non-seismic items in the nuclear island are separately arranged, and non-seismic items in the original seismic I-type plant are arranged in the auxiliary plant. Due to the fact that the price of the non-earthquake-resistant structures is far lower than that of earthquake-resistant I-type structures, the nuclear island earthquake-resistant I-type structures can be reduced, the civil engineering investment cost is reduced, and the economical efficiency of the nuclear power unit is finally improved on the premise that various functions of the nuclear island plant are met.
The above-described embodiments are merely illustrative of the present invention, which may be embodied in other specific forms or in other specific forms without departing from the spirit or essential characteristics thereof. The described embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
