Part 21 Initial Notification for Flowserve Model 28KXL Pump Impeller Defect This Part 21 initial notification addresses a pump impeller defect that resulted in a post maintenance test (PMT) failure. The OC RHR Service Water Pump was being replaced due to degraded performance which caused an In-Service Test (IST) failure.
The replacement pump impeller received from the supplier had not been machined to the purchase order specifications. The IST of the new pump could not be completed since the required test conditions could not be established. The pump was later replaced and the IST was completed successfully. The pump was declared operable on March 2, 2013.
This Part 21 Initial Notification is being submitted pursuant to the requirements of 10CFR21.21 (d)(3)(i).
