Nuclear island exhaust and water delivery pipe network system for mega-kilowatt nuclear power plants

Abstract

This application relates to the technical field of nuclear auxiliary systems of nuclear power plants, and discloses a nuclear island exhaust and water delivery pipe network system for mega-kilowatt nuclear power plants, including a first pump set, a first drain pipeline, a second pump set, a Two drain pipelines and containment drain pits. The first pump group includes a first water pump and a first drain pan, one end of the first drain line communicates with the first drain pan, and the leakage water in the first drain pan is discharged into the first drain line. The second pump set includes a second water pump and a second water receiving pan, and one end of the second drainage pipeline communicates with the second water receiving pan. The other end of the first drainage pipeline and the second drainage pipeline converge into one pipeline and extend to the containment drainage pit. In the improved nuclear island exhaust and water delivery pipe network system, an independent drainage line is formed between the first drain line and the second drain line and the containment drain pit, which can meet the requirements of the first drain line and the second drain line. The pipeline's demand for drainage volume and drainage speed is conducive to solving the problem of wastewater backflow.

Description

technical field [0001] The present application relates to the technical field of nuclear auxiliary systems for nuclear power plants, and in particular, to a nuclear island exhaust and water delivery pipe network system for a million-kilowatt nuclear power plant. Background technique [0002] In the original nuclear island exhaust and water pipeline 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, and 001 / 002PO is the two water pumps. No.) A sketch of the schematic diagram of the connection of the drain line in the water tray. The drain line of the RPE001 / 002PO water receiving tray of L1 / 2 machine is connected with the RPE pipe network, and there is no isolation valve between the water delivery pipeline of the water receiving tray and the RPE pipe network. Therefore, whe...
