Abstract

Screening test and study of air-water cold condition for dryer in steam generator for 1000MW PWR nuclear power plant was conducted.The dryer with optimized design features was obtained by the tests.Separation component of the dryer employed the double-hooked chevrons.Space between hook and chevron decreased gradually from the inlet to the outlet of the dryer;Baffle perforated asymmetrically was set in the inlet of the dryer;Diameter of hole on the baffle decreased from the bottom to the top.The tests indicated that this type dryer possessed higher critical velocity.
- Double-hooked chevron,
- Perforated baffle,
- Draining hook,
- Critical velocity
