DescriptionKimmon Quartz 200-BC2 Corrosion Product Samplers
OverviewSingle and dual channel corrosion product samplers, each available with or without sample coolers. Additionally, allsamplers include bypass flow capability. This configuration, as illustrated in Figure 1, provides the ability to process a sample from any point in the cycle while maintaining a high sample line Reynolds number via the bypass system.A 0.45 mm filter is generally used to collect filterable species from a continuous sample flow with a cation ion exchange membrane inserted below the filter to collect soluble cationic species and possibly colloidal species passing through the 0.45 mm filter.With a sample flow of 100 ml/min for 24 hours, the membrane packet accumulates the impurities present in a 144-liter sample. Pressure regulation is provided to maintain a constant sample flow as the pressure drop across the membranes increases with time. The flow Totalizer furnishes an accurate value for the total sample volume of the period.
Key FeaturesHigh bypass flow capability (up to 2.2 liters/min.). Pressure regulation downstream of the filter holder to maintain constant sample flow. As a result, constant sample flow is assured as the differential pressure across the filter membranes increases with time. Sample flow totalizing (mechanical with ±3.0% accuracy). Samplers provided in cabinets with clearly illustrated flow schematic on panel
Typical ApplicationsAs stated in the PWR Secondary Water Chemistry Guidelines (EPRI NP-5056-SR): “This sample collection method allows long-term averaging of corrosion product concentrations thereby providing a firm basis for performing mass balances around specific components, e.g., it is possible to identify major sources of corrosion products within the feedwater system.”
