SUMMARY
SUBCATEGORY / ELEMENT 229.6(B)
The " Water Quality Monitoring" (System 43), properly titled " Sampling and Water Quality Monitoring," is not safeiy-related.
System 43 is expected to contain some radioactive contamination under some normal and accident conditions. The small quantity and relatively low expected contamination levels do not present a significant hazard. Where such contamination is expected the drains are processed through the closed floor drain system which goes to Radwaste for decontamination processing. The ability to turn off flow and the ability to draw a sample indicates the presence of sufficient valves for isolation and maintenance purposes. This issue is related to an on-going investigation in Element 229.2.
