| Title | Feedwater Pipe Support Issues |
| Description | A URI was identified by the inspectors relating to an issue involving feedwater pipe supports on Units 1 and 2. On November 10, 2009, the licensee initiated CR357450 for a NRC identified issue with a Unit 1 C feedwater pipe support, 1-FW-PH-13, involving no contact between the floor-mounted section of the support and the section attached to the pipe. The inspectors expressed concerns regarding the impact on feedwater piping for both units because the licensee had completed a modification installing new ultrasonic flow instruments for the feedwater piping and had removed/installed the feedwater flow venturi for cleaning during the previous refueling outages. An extent of condition review was performed by the licensee and additional problems were identified with Unit 2 A feedwater pipe supports, 2-FW-PH-18 and 2-FW-PH-20.The inspectors require additional information from the licensee to determine if there is a performance deficiency which is greater that minor. This issue is identified as URI05000338, 339/2009005-02, Feedwater Pipe Support Issues. |
