Fouling in nuclear once-through steam generators

OSTI ID:5151746
The contaminants in feedwater have required utilities to take expensive remedial actions in the steam generators of nuclear steam systems, including completely replacing the heat transfer surface. This paper describes a consequence unique to the Babcock and Wilcox nuclear once-through steam generator - the potential for reduction of steam generation rate due to increased flow resistance in the nucleate boiling region. Feedwater flow and thereby power level has had to be reduced to prevent ''flooding'' of the downcomer. Hydraulically removing the deposits responsible for the increased pressure drop has been partially successful. Chemical cleaning is expected to restore performance.
