Abstract

Abstract

The mechanism of reverse flow in inverted U-tubes of steam generators of pressurized water reactors during natural circulation is analyzed by using the full range characteristic curve of parallel U-tubes.A lumped?distributed model to calculate the reverse flow occurred in inverted U-tubes of real steam genera-a well agreement with that predicted by the model in which normal or reverse flow in each individual U-tube is analyzed,which verifies the reliability of the model developed in this paper.
