Problems solved by technology

However, considering that there will be a large number of alarm signals in the fire prevention space, including false alarms, many indicators display wrong information, which have a significant impact on the operation of the unit, and cause serious damage to the operator's judgment on the status of the unit. great trouble
If these false information cause the operator to improperly execute the loss of support system procedures, improperly shut down the support system required to perform the safety function, and then hinder the execution of the safety function, forming a "common mode of operation"
The current technical solution cannot identify and deal with the "common mode of operation" in this situation. In the event of a fire, the nuclear power plant still has the risk of losing all safety functions

Embodiment 1

[0053] The embodiment of the present invention provides a method for processing the common mode of nuclear power plant fire operation, see figure 1 , the method includes:

[0054]S101. Identify the support system that affects the safety function of the nuclear power plant, and obtain the corresponding loss support system program;

[0055] S102. In the event of a fire, analyze the consequences of executing the program of the loss of support system and the direct fire consequences of the involved fire compartments;

[0056] S103. If it is analyzed that there is an operation common mode risk, take protective measures to eliminate the operation common mode risk.

[0057] It should be noted that the support system does not directly perform safety functions (functions required to ensure the safe operation of nuclear power plants, including the functions of realizing reactivity control, core heat removal, shielding and containment of radioactive materials, etc.), it provides equipme...

Embodiment 2

[0097] An embodiment of the present invention provides a nuclear power plant fire operation common mode processing system, which can realize all the processes of the above nuclear power plant fire operation common mode processing method, see Figure 9 , the system consists of:

[0098] Program acquisition module 1, used to identify the support system that affects the safety function of the nuclear power plant, and acquire the corresponding loss support system program;

[0099] analysis module 2 for analyzing, in case of fire, the consequences of implementing said loss of support system procedures and the immediate consequences of the fire for the involved fire compartments; and,

[0100] The measure taking module 3 is used to take protective measures to eliminate the operation common mode risk if it is analyzed that there is an operation common mode risk.

[0101] Further, the processing system of the nuclear power plant fire operation common mode also includes:

[0102] an ...

Abstract

The invention discloses a processing method for a fire operation common mode of a nuclear power plant. The method comprises: a support system influencing the safety function of a nuclear power plant is identified and a corresponding loss-of-support-system program is obtained; when a fire occurs, a result of performing the loss-of-support-system program as well as a direct fire result of an involved fire protection sub zone is analyzed; and if the analysis result shows the existence of an operation common mode risk, a protection measure is taken to eliminate the operation common mode risk. In addition, the invention also discloses a processing system for a fire operation common mode of a nuclear power plant. With the processing method and system disclosed by the invention, the operation common mode risk can be eliminated under the circumstance that the operation common mode is caused by mis triggering of a fire or execution of the loss-of-support-system program by mistake, so that the safety function is protected with the occurrence of the fire and thus the fire safety level of the nuclear power plant is improved.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to a method and system for processing common modes of nuclear power plant fire operations. Background technique [0002] Fire is one of the external disasters that nuclear power plants must consider. The fire protection design of nuclear power plants should not only consider reducing the possibility of fire occurrence, but also reduce the consequences of fire occurrence. The ultimate goal is to ensure that fires in any area of ​​the nuclear power plant Neither can lead to the loss of the safety function of the nuclear power plant. At present, nuclear power plants generally separate and arrange redundant equipment performing the same safety function by dividing fire compartments, supplemented by fire doors, smoke exhaust valves and other fire protection facilities to limit the consequences of a fire in a certain area, and prevent the fire from spreading to adjacent fire ...
