Study on Noise Environmental Impact and Prevention Measures of the Natural Ventilation Cooling Tower in a Nuclear Power Plant
摘要
Abstract
The noise generation mechanism and source intensity characteristics of natural ventilation cooling towers are discussed, and the applicability of the noise attenuation calculation model in HJ2.4-2009 guidelines is analyzed. With the cooling tower of an inland nuclear power plant as an example, using the noise attenuation calculation model in the guideline, the noise influence of the cooling tower is analyzed, and the conclusion is proposed. The main noise control measures for cooling towers are summarized. According to the environmental protection regulation and the requirement that the nuclear power plant needs to set up a certain range of exclusion area, it is suggested that the noise emission assessment point of the natural ventilation cooling tower be extended from the red line of land to the boundary of the exclusion area, or to the envelop of the exclusion area and the red line of land. Then, synthesizing the distribution of sensitive points around the area and the monitoring results in trial operation period, a technically economical, reasonable and feasible noise reduction scheme is proposed and applied. This scheme can solve the noise problem and accord with the actual situation of the enterprise as well as reduce the cost of environment protection investment.关键词
