Performance Evaluation of a Passive Safety Injection Flow Controller for APR1400

摘要

A series of experiments have been carried out for two models of fluidic device using thernfull-scale test facility called VAPER(Valve Performance Evaluation test Rig), in order tornevaluate the performance of safety injection tank (SIT) of APR1400. The present paperrnmainly describes the experimental results obtained for model II fluidic device, such asrndischarge flow characteristics, duration of discharge flow, and water level depression in thernstand pipe, etc. The results of model I fluidic device can be found in the previous work[1].rnBoth the two models satisfy the primary performance requirements suggested by the nuclearrnpower plant system designer. However, the model II fluidic device shows improvedrnperformance.
