Subject:
8" line Ron, it is referenced as SS-4 in the report.
The 8-inch CS line (SS-4/CS-25) is the Hotwell Level Control supply line from the Condensate Pump discharge header to flow control valve V-2-17. This line is pressurized to between 200 psig to 250 psig during normal operation. Upon developing a through wall leak in the pipe, leakage would immediately exit the pipe and enter the surrounding soil. This line was assessed as a Low Risk factor since it is a direct buried CS line. This line was assessed a Medium Radiological Consequence factor since a leak could lead to an unmonitored release and a Medium Consequence factor since a significant leak could lead to a plant shutdown.
