Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The first span of the steam turbine factory building provided by the invention can be divided into seven layout floors according to its elevation, including one underground floor and six floors above the ground. The layout of this structure effectively solves the problem of tight space for equipment layout.

[0030] Such as figure 1 Shown is the floor plan of the underground floor, which is arranged at -8.00m. This layer is sequentially provided with transverse A-axis, B-axis, C-axis, D-axis, E-axis, F-axis, G-axis, H-axis, J-axis, K-axis and L-axis.

[0031] For the maintenance and drainage of equipment, there is an equipment cooling water system heat exchanger room 6 between the A axis and the D axis, and a chilled water system equipment room 7 between the cold F axis and the K axis. Among them, two heat excha...

Abstract

The invention provides a method for arranging a first span of a nuclear power station steam turbine plant. The first span comprises an underground floor and six floors on the ground, and mechanical equipment, electrical equipment and ventilation equipment in the plant are arranged in a layered mode through the first span. Radioactive equipment is arranged in a radioactive control area in a centralized mode, the area is shielded, and the danger that radioactive substances directly pollute the plant and nearby areas is avoided. On the premise of guaranteeing system function completeness, the span of the plant is increased properly, a personnel channel is additionally arranged, equipment mounting, maintenance and passing requirements are met, and the problem that equipment arrangement space is uptight is solved. Meanwhile, the area containing the radioactive substances is controlled strictly, and various functions of the plant can be achieved more reasonably.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant steam turbine building design, and in particular relates to a method for arranging the first span of a nuclear power plant steam turbine building. Background technique [0002] The building structure between the first axis and the second axis of the steam turbine building of AP1000 nuclear power plant is called the first span of the steam turbine building. The first span is adjacent to the nuclear island auxiliary plant, auxiliary plant and steam turbine plant hall, and is an important plant connecting the nuclear island and the conventional island. [0003] The plant mainly involves equipment cooling water system, evaporator sewage system, chemical and volume control system, main steam system, main water supply and start-up water supply system, plant water system, demineralized water system, compressed air and instrument air system, power plant gas system, fire protection system, mai...
