Embodiment 1
[0072] see Figure 1 to Figure 3 , the online optimization method for the nuclear power plant fire pipe network provided by the present invention will now be described. The on-line optimization method of the nuclear power plant fire control pipe network includes the following steps:
[0073] Prefabrication stage F0: Select a connecting pipeline 38 close to the location of the main engine fire-fighting pipe network 20 on the branch line 31 connecting each set of main engine fire-fighting pipe network 20 to the peripheral fire-fighting pipe network 30, and the two ends of the connecting pipeline 38 have respectively Lan 381, then detect the size of the communication pipeline 38; prefabricate a replacement pipeline 71 with the same size as the communication pipeline 38 according to the size of the communication pipeline 38, and the replacement pipeline 71 is provided with an isolating valve 72;
[0074] Preparation stage S1: use the main temporary pipeline 61 to connect the exte...

[0087] Further, see Figure 1 to Figure 3 , as a specific implementation of the online optimization method for nuclear power plant fire protection pipe network provided by the present invention, the block isolation S4 step specifically includes:
[0088] The first isolation block S41: closing the valves from each of the host fire-fighting pipe networks 20 to the peripheral fire-fighting pipe network 30;
[0089] The second isolation block S42: close the valves connecting the fire-fighting water pump group 11 to each of the host fire-fighting pipe networks 20;
[0090] The third isolation block S43: closing the isolation valves in the peripheral fire-fighting pipeline network 30 before connecting to the host fire-fighting pipeline networks 20 .
[0091] Through the step of the above-mentioned first isolation block S41, the fire-fighting water in the host fire-fighting pipe network 20 is prevented from entering the peripheral fire-fighting pipe network 30 . Through the step of...

[0106] Further, see Figure 1 to Figure 3 , as a specific implementation of the online optimization method for nuclear power plant fire protection pipe network provided by the present invention, the emergency response F2 step also includes steps before:
[0107] Operation alert F12: Prohibit hot work in the corresponding areas of each steam turbine unit system and the corresponding areas of peripheral auxiliary systems; to reduce safety risks during pipeline replacement operations.
[0108] After the step of completing operation S7, it also includes the step of releasing the prohibition of hot work in the corresponding areas of each steam turbine unit system and the corresponding areas of peripheral auxiliary systems. In order to resume the normal operation and work of the personnel after completing operation S7.
[0109] Further, see Figure 1 to Figure 3 , as a specific implementation of the online optimization method for nuclear power plant fire pipe network provided by t...
