Research On Design And Safety Evaluation Of The Charging Pump Room Emergency Ventilation In Nuclear Power Plant Under Different Working Conditions

Nuclear power plants are places where electricity generated by nuclear fission is used to generate electricity.Among the numerous equipments in nuclear power plants,ventilation equipment is one of the key equipment to ensure the normal operation of nuclear power plants.Its main role is to create a safe operating environment for the equipment,control the emission of polluting gases and provide a comfortable working environment for the operator.The normal operation of ventilation equipment is one of the prerequisites for ensuring the safe operation of other nuclear power equipment.The ventilation performance has an important impact on the safety of the entire nuclear power plant.As an important part of the nuclear power plant ventilation system,the charging system of the pumping house in the nuclear power plant is particularly important to ensure that the DVH(Charging Pump Room Emergency Ventilation)meets the design requirements and actual effects of the nuclear power plant.Therefore,it is necessary to study in depth the various indicators of the Charging Pump Room Emergency Ventilation.This paper combs the relevant theoretical research on the ventilation system of nuclear power plants,and analyzes the existing problems and related elements of the Charging Pump Room Emergency Ventilation.Based on the design of the ventilation system of the pumping house in the nuclear power plant and the research ideas of the data verification analysis of different working conditions,the paper validates the actual data of the typical working conditions of the pumping station to verify the reliability of the ventilation system of the pumping room.Sex.Due to the analysis and research of empirical data,this paper has strong practical application value and has certain reference value for the design of ventilation system of pumping room.The research ideas and contents of this paper include the following parts:(1)Design and research on the ventilation system of the pumping house in the nuclear power plant,and gave detailed parameters and design requirements for each sub-module of the design system.(2)Through the analysis and calculation of three typical working conditions of the pumping house in the nuclear power plant,it is verified that the ventilation system of the upper pumping room meets the design requirements.(3)Classified the safety risks of the pumping and ventilation system on the nuclear power plant,and proposed a safety risk.Corresponding risk control measures.
