Embodiment Construction

[0026] The method for safety and fire compartments of nuclear island plant buildings of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the nuclear island powerhouse safety fire zoning method of the present invention, it carries out successively according to the following steps:

[0028] (1) Divide safety fire compartments:

[0029] First understand the civil structure, room layout, and safety system settings of the nuclear island plant, and then divide the different series of equipment that perform the same safety function in the nuclear island plant into different safety and fire protection zones according to the principle of isolating different safety series;

[0030] (2) Determine the type of each safety fire compartment:

[0031] If the content of combustibles in the safety fire compartment meets the requirements of diffuse fire, and the equipment that perfo...

Abstract

The invention relates to a safety fire zone dividing method for a nuclear island factory building, which comprises the following steps: (1) dividing safety fire zones; (2) determining the type of each safety fire zone; (3) determining the fire endurance of each safety fire zone; and (4) arranging a fire boundary device on the boundary of each safety fire zone. The method can fully divide the safety fire zones for a safety system of the nuclear island factory building, can effectively isolate different safety series of devices and parts for executing the same safety function, and avoids the same fire causing common model fault of different series of devices for executing a certain safety function.

Description

technical field [0001] The invention relates to a method for safe fire compartments suitable for nuclear island workshops of nuclear power plants. Background technique [0002] At present, the fire compartment method adopted by most nuclear power plants and nuclear island buildings is mainly aimed at combustible materials with high fire hazards, and it is more inclined to conduct fire compartments for fire loads. The existing method calculates the fire load value based on the equipment installed in the nuclear island workshop of the nuclear power plant, and treats the part with a large fire load value as a fire protection zone, focusing on eliminating the fire at the source. However, this approach cannot provide a comprehensive fire compartment for the safety system of the nuclear island plant, and has the risk of failure of the safety function in case of fire. Contents of the invention [0003] The purpose of the present invention is to provide a method for safety and fi...
