EVENT TEXT DRESSER VALVES NAME PLATE AND CODE PLATE HAVE INCORRECT SET PRESSURE INFORMATION AT HATCH.

PART 21 FROM DRESSER EQUIPMENT GROUP, DRESSER VALVE DIVISION, BURLINGTON, ONTARIO, CANADA.

The following noncompliance has been determined to be reportable within the requirements of 10CFR Part 21. The noncompliance involves seven safety relief valves that were purchased for the Hatch Electric Generating Plant by the Georgia Power Company through its agent, Southern Nuclear Operating Company, Inc. The valves are for use in a safely related service.

The valves were purchased on Southern Nuclear Operating Company purchase order #6040304 and produced on Dresser Valve Division sales order #119588N and are further described as follows:

Contract Item 002 Quantity 7 Part Number 3990C-1-S4-MS-33-SC-SC-GS produced ASME Section III Class 2 valves with the following serial numbers and required set pressures:


SERIAL NO. SET PRESSURE REQD

NONCOMPLIANCE SITUATION AND BRIEF HISTORY

On Tuesday April 25, 2000, the customer was performing receiving inspection and noticed that the set pressure information on the Code Plates and the Name Plates do not conform to the specification requirements or the history docket testing information. The customer called the Quality Assurance Department of Dresser Valve Division to discuss the finding. It appears that the set pressure information on the plates has been interchanged.

A summary of the information is as follows:

Our investigation has begun and we have conducted a full review of our records to confirm that the valves are set correctly to the contract requirements. A notice has been given to the customer to return the affected valves to Dresser Valve Division for confirmation of the plate information and correction if required. The ANI will be involved in the investigation and corrective actions as required.

We have conducted a full review of our records and confirmed that these are the only valves involved. A full review of our procedures regarding plate preparation, inspection and installation will be completed. Corrective actions will be initiated to address the internal issues, if warranted, and details will be provided in our closure reports at the completion of our investigation into the cause of this situation.
