Abstract

The invention relates to the technical field of nuclear power station nuclear auxiliary systems, and discloses a nuclear island exhaust and water delivery pipe network system for a million-kilowatt nuclear power station. The system comprises a first pump set, a first drainage pipeline, a second pump set, a second drainage pipeline and a containment drainage pit. The first pump set comprises a first water pump and a first water pan, one end of the first drainage pipeline is communicated with the first water pan, and leaked water in the first water pan is drained into the first drainage pipeline. The second pump set comprises a second water pump and a second water pan, and one end of the second drainage pipeline communicates with the second water pan. The other ends of the first drainage pipeline and the second drainage pipeline are converged into a pipeline and extend to the containment drainage pit. In the improved nuclear island exhaust and water delivery pipe network system, independent drainage lines are formed between the first drainage pipeline and the containment drainage pit and between the second drainage pipeline and the containment drainage pit, the lines can meet the requirements of the first drainage pipeline and the second drainage pipeline for the drainage amount and the drainage speed, and the problem of wastewater backflow is solved.

Description

technical field [0001] The present application relates to the technical field of nuclear auxiliary systems of nuclear power plants, in particular to a nuclear island exhaust and water delivery pipe network system for mega-kilowatt nuclear power plants. Background technique [0002] In the original nuclear island exhaust and water pipe network system, please refer to figure 1 , figure 1 It is the original L1 / 2RPE001 / 002PO (L1 / 2RPE001 / 002PO is the abbreviation of nuclear power equipment. L1 / 2 is the nuclear power plant unit 1 and 2, RPE is the nuclear island exhaust and drainage system, 001 / 002PO is the two water pumps No.) A simplified diagram of the connection diagram of the drain pan drain line. The drainage pipeline of RPE001 / 002PO water receiving pan of L1 / 2 unit is connected with the RPE pipe network, and there is no isolation valve between the water delivery pipeline of the water receiving pan and the RPE pipe network. Therefore, when the amount of water in the RPE p...
