The invention relates to a multi-module type high-temperature gas cooled reactor nuclear power station water supply system. The multi-module type high-temperature gas cooled reactor nuclear power station water supply system comprises a deaerator, a first pipeline, a water supply pump set, a second pipeline, a high-pressure heater, a first main pipe and two or more third pipelines; the deaerator is communicated with one end of the first pipeline, the other end of the first pipeline is communicated with one end of the second pipeline, the other end of the second pipeline is communicated with the water inlet side of the first main pipe, one end of each third pipeline is used for being communicated to an NSSS module, and the other end of each third pipeline is communicated with the water outlet side of the first main pipe. The water supply pump set is arranged on the first pipeline, and the high-pressure heater is arranged on the second pipeline. Compared with a traditional multi-module type high-temperature gas cooled reactor nuclear power station water supply system, the first main pipe is added, and distributes high-temperature high-pressure water to two or more NSSS modules, the occupied area is greatly reduced through one water supply pump set and one high-pressure heater, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of multi-module high-temperature gas-cooled reactor nuclear power plants, in particular to a water supply system for multi-module high-temperature gas-cooled reactor nuclear power plants. Background technique [0002] The traditional multi-module high-temperature gas-cooled reactor nuclear power plant feed water system includes a deaerator, more than two feed water pump sets and more than two high-pressure heaters. The feedwater pump set, high pressure heater and NSSS (Nuclear Steam Supply System) modules are set up accordingly, and the feedwater pump set is connected to the deaerator. After the deoxygenated water in the deaerator enters each feedwater pump group, the feedwater pump group pumps the deoxygenated water to the high-pressure heater, which is heated by the high-pressure heater and then sent to the NSSS module. However, more than two feed pump sets and more than two high-pressure heaters in the w...
