Corrosion product monitoring method and system.

摘要

A corrosion product monitoring system and method are described using recirculation loop including a sample line, a particulate collection vessel, a recirculating pump, a microporous membrane "cross-flow" filter, and valves to control the flow rate and pressure of a sample fluid taken from the secondary fluid system of a nuclear power plant. The related method includes the steps of: taking a sample from the fluid system; introducing the sample to a recirculation loop having an initial system volume; separating non-soluble particulates from soluble contaminants; suspending the solid particulates; collecting the solid particulates in a particulate collection vessel; and determining a corrosion concentration factor from the total sample volume divided by the initial system volume.
