Steam Dryers for extended power up-rated conditions, based on a design with proven performance record, have been designed by Westinghouse with performance characteristics meeting all utility requirements. Extensive CFD analysis has been used to design the new dryer intended for the BWR 3000 plants. The analysis has utilized previous knowledge, acquired from experimental work, on steam flow characteristics in the BWR 3000 with its asymmetrically placed steam line nozzles. A design has been developed that is predicted to both decrease vibration levels and to solve a water-level measurement problem. An extensive experimental verification of the design is presently done.
