SAPN 50341879 (Regulator Material)

Importance: High

Greg, I've updated the notification indicating that we will perform the walkdown and update the LRA to reflect the correct material as part of the annual update. SAP must be down. I am not able to download the notification to email to you this afternoon. However, I will email you the updated notification tomorrow morning.

Thanks, Miranda 805 781 9415 09/20/2010 14:34:18 Jana M. Orlando (JMSO) Phone 805/545-3126 09/16/2010 14:46:12 Philippe R. Soenen (PNS3) Phone 805/781-9782 During a license renewal regional inspection walkdown the material type for the Unit 2 AIR-I-I-1231A regulator was questions when compared to what SAP identifies the material to be. SAP identifies this component to be made of aluminum whereas the walkdown identified this component to be some type of copper alloy.

The component material needs to be verified int he field and SAP should be revised as necessary to reflect the actual material type.

The license renewal application and the basis documents need to be revised as appropriate to reflect the correct material type.

There is no operability or functinal concern with this component it is only a documentation clarification.
