Measures to Improve Instrument Reliability of Main Water Feeding Pumps in Nuclear Plants
In order to facilitate further improvement of operational reliability of main water feeding pump instruments in nuclear power plants,this paper describes the instrumental operational defects of a main water feeding pump in an actual nuclear plant,including abnormal fluctuations,sealing failure,component aging,measurement deviation,and backup fault alarm logic problems.It elaborates on the reliability improvement measures in detail and summarizes the improve-ment effects and future promotion directions.
