Performance verification test for APR1400 fluidic device

Using the full scale test facility called 'VAPER', five sets of repeatability tests have been carried out to verify the performance of the Fluidic Device which is adopted in the standard design of APR1400. Quality assurance program for the APR1400 Fluidic Device verification test has been developed and applied to each set of repeatability test procedure, and precise calibration for major measuring instruments has been performed. Thus, the highest reliability and integrity of the test results was ensured. Throughout the present tests, the repeatability of the major parameter related with APR1400 Fluidic Device performance has been sufficiently confirmed. Total K factor in the actual plant system would be about 16 at high flow condition and about 105 at low flow condition, which is similar to the design goal (about 17 at high flow condition and about 100 at low flow condition) The results of the present research contributes to the smooth construction of Sin-Kori units 3 and 4, and to the promotion of domestic analytic capability for the LOCA of advanced LWR
