Fire control system for bulging testing of containment of nuclear power plant and configuration method of fire control system

Abstract

The invention provides a fire control system for bulging testing of a containment of a nuclear power plant and a configuration method of the fire control system. The fire control system comprises a containment spray system, a nuclear island fire extinguishing system and a standby fire extinguishing system, wherein the standby fire extinguishing system comprises an overhead tank, a temporary pipeline, at least two conveying pumps and at least two temporary power supplies, wherein the overhead tank is used for providing a fire water source; one end of the temporary pipeline is connected with theoverhead tank, and the other end of the temporary pipeline is connected with pipelines of the containment spray system and the nuclear island fire extinguishing system separately so as to introduce fire water into the containment; the at least two conveying pumps are connected in parallel and are arranged on the temporary pipeline so as to convey the fire water; each temporary power supply is simultaneously connected with the at least two conveying pumps so as to provide a redundant power supply. According to the fire control system for bulging testing of the containment of the nuclear powerplant and the configuration method of the fire control system, provided by the invention, available resources of the nuclear power plant are utilized, the equipment debugging cycle is short, the costis low, and thus, the fire control system and the configuration method thereof have relatively high economical efficiency and practicability.

Description

technical field [0001] The invention relates to the technical field of fire-fighting systems, in particular to a fire-fighting system and a configuration method thereof used during a containment pressure test of a nuclear power plant. Background technique [0002] The containment vessel of a nuclear power plant is the third barrier to prevent the leakage of fission products, and is used to contain radioactive materials and shield radiation under operating conditions and accident conditions. According to the design requirements, the containment vessel of a nuclear power plant needs to undergo a containment compression test (CTT) during the commissioning phase during construction, the first overhaul after commercial operation, and every ten years to verify whether the overall sealing and mechanical strength of the containment vessel meet the design requirements . During the containment pressure test, the internal pressure of the containment is relatively high, and the oxygen ...

AI Technical Summary

Problems solved by technology

The construction of a nuclear power plant is an extremely large and complex system project. Various problems may be encountered during the construction process, which may cause the cold-state functional test to be unable to proceed as planned. Satisfying the requirements but not having the starting conditions, resulting in the inability to complete the cold-state functional test and containment pressure test, affecting the overall commissioning progress of the nuclear power plant, thereby affecting the final commercial operation
