water treatment as described for boiling water reactors. Most
structural components are also fabricated from stainless steel with
corrosion characteristics as described for the piping.

8.5.7 Corrosion Costs to the Power Industry
A detailed example of cost data for corrosion problems affecting the
various broad sectors of the electric power industry has recently been
published for the United States [15;16]. The compiled and sorted costs
are presented in Table 8.10 with the highest cost listed first. These
dollar amounts include corrosion-related costs associated with both
operations and maintenance and depreciation. They also include
both direct and indirect corrosion-related costs.
