BWR steam dryer for extended power uprate

A new steam dryer for extended power uprated conditions, based on a design with proven performance record, has been designed by Westinghouse with performance characteristics meeting all utility requirements. Extensive use of computational fluid dynamics (CFDs) has been made to design the new dryer intended for plants of the BWR 3000-type. In addition to numerical simulations, the analyses rely on previous knowledge, acquired from experimental work on steam flow characteristics in the BWR 3000 with its asymmetrically placed steam line nozzles. The new design is expected to both decrease vibration levels in the steam lines and to solve a water-level measurement problem. An extensive experimental verification of the new design is currently in progress.
