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.
