The March 13-14, 1979 EPRI sponsored workshop on design, operation and maintenance problems with nuclear feedwater heaters identified a large number of significant technical areas of concern. The reported problems relate to nearly all facets of feedwater heater technology. In particular, hydrometallurgical problems such as stress corrosion of stainless tubing, erosion/corrosion wear of tube-tubesheet joints, and flashing related tube erosion at the entrance to the drain cooler region were reviewed in depth. Shortcomings in current design standards and design specifications were also discussed. Solutions to specific technical problems such as mechanics of flow induced vibration failures, improved synthesis of feedwater heater orientation with plant layout, and drain outlet piping design were presented. A list of important technical problems requiring additional research and development for improved design guidelines was developed. The proceedings contain all edited material of archival quality developed in this workshop.
