Power Plant Water Chemistry Research at EPRI in the 1990's

Source

The objective of plant water chemistry research at EPRI will continue to be the reduction of component damage by corrosive attack by the water and steam coolants. New chemistries will be evolutionary from the present practices by improving our surveillance of impurities, finding new additives to control pH and oxidizing power, and developing improved water treatment methods. Surveillance of the state of the coolant on-line as contrasted with existing grab sampling at infrequent intervals will require improved probes for such purposes. It is likely that different chemistries will be needed for different piping metallurgies, though the current common ones are not seriously different except for those with and without copper alloys. Improved guidelines for chemistry practices and limits are expected to be needed, but a number of those now in place should require little change.
