Performance Evaluation of Passive Safety Injection Flow Controllers for the APR1400 Reactor

This paper provides experimental results obtained in the full-scale tests for the performance evaluation of the Fluidic Device which is expected to be adopted in a Korean next generation reactor (APR1400). The tests have been carried out using the full-scale test facility called VAPER (Valve Performance Evaluation test Rig). Following characteristics of the fluidic device are investigated in the present work: peak discharge flow rate, duration of high flow, flow rate switching function, water level depression in stand pipe, etc. Experimental results show that the present fluidic device meets the primary performance requirements of APR1400 plant design.Copyright © 2002 by ASME
