Abstract
In nuclear power plants,the application of Class 1E batteries is critical.They can serve as the last safety protection barrier when problems arise in the power supply of nuclear power plants,thereby ensuring the safe operation of nuclear power plant equipment.Therefore,the choice of Class 1E batteries is critical.As a valve-regulated sealed lead-acid battery,VRLA battery has the characteristics of strong tightness,high safety,and low cost.If it is used as a 1E-class battery in a nuclear power plant,it can effectively meet its functional requirements.Based on this,taking the characteristics of VRLA batteries and 1E-class batteries as the starting point,we briefly discuss the feasibility judgment principles of VRLA batteries as 1E-class batteries in nuclear power plants,and analyze six failure modes:positive grid corrosion,positive active material softening,negative bus corrosion,electrolyte dryness,thermal runaway,and irreversible sulfation,thus providing reference for the feasibility analysis of VRLA batteries as 1E-class batteries in nuclear power plants.关键词
