abstract

KAERI has performed a series of blowdown tests to assess the performance of prototypic steam sparger which will be used in a APR1400 reactor. The test program consists of 22 blowdown tests and each test simulates air clearing phase during an opening of depressurization valves. The major test parameters include air mass in the discharge line, air temperature, flow area, valve opening time, IRWST water temperature, and submergence of a sparger. The CPT-3 test was conducted for typical PWR condition. Following valve actuation, the pressure within the discharge line underwent pressure transient and the discharged high pressure air formed air bubbles, which expanded and compressed periodically in the simulated IRWST. Loop behavior as well as hydraulic load caused by air bubble oscillation during the air clearing phase were described. In addition, water level variation in the sparger during operation of a vacuum breaker was also discussed.
