Feedwater heaters are often forgotten in condition assessments plans. While they have no moving parts, these components have a significant impact on plant performance equivalent availability. Condition assessment of feedwater heaters includes not only an analysis of the tubing, which because of its thin wall nature is the primary objective of analysis, but other failure causes, such as tube joint leaks, an adverse condition which can and often does occur. For these reasons a comprehensive condition assessment program should be employed. This paper will identify the three level approach suggested by EPRI and many of the testing methods used to assess feedwater heater condition.
