This report compiles field operating experience and maintenance of some of the following PWRs components: heaters and reheaters, pumps, valves, piping and their supports, heat exchangers and bolted connections. Reactor coolant pumps, steam generators and primary system piping are excluded as presented in other reports.

The report is separated in two sections.

The first section is dedicated to the feedwater plant and other secondary system components, i.e.: feedwater plant reheaters, moisture separator re-heaters, feedwater plant pumps and steam generator turbine driven auxiliary feedwater pumps.
The second section is dedicated to mechanical components, i.e.: piping and supports, valves, pumps and bolted connections.
