Subject:

10CFR21 Report Masoneilan Valve Parts Deficiencies Docket .50-255 License DPR-20-Palisades

Dear Mr. Grimes:

This letter is to inform the USNRC of the potential for counterfeit Masoneilan parts being supplied to Commercial Nuclear facilities.

On October 21, 1988, a 10CFR21 report was filed to the USNRC by Consumers Power (ref. Docket 50-255, License DPR-20 Palisades Plant). In that report, valve parts purported to be of Masoneilan manufacture were in fact manufactured by unauthorized sources. These counterfeit parts were supplied by an authorized Masoneilan representative in violation of Masoneilan policy and on their own initi,ative. These parts were not manufactured to Masoneilan standards and the potential for subseQuent valve malfunction exists. All identified parts have been segregated and are being replaced.

Because of this unauthorized action, an evaluation must be performed by the plant licensees, to determine if this is an isolated occurrence.

In this case, Non-Q parts procured commercially were dedicated into Q valves. On site service by Masoneilan personnel identified several parts of other than Masoneilan manufacture.

Counterfeit parts identified at this plant were:

- _____________ ----- - --P-h1g- stem---- -------- --- - -----

Stem to plug anti-rotation pin Seat ring

SUBJECT:

10CFR21 Report Masoneilan Valve Parts Deficiencies PAGE 2 In addition the potential for additional counterfeit parts exists in the realm of turned machine parts such as:

Valve plugs Bushings Cages Packing box components Counterfeit machined parts are often difficult to distinguish from original equipment parts.

An independent investigation by Masoneilan is under way to determine if similar circumstances have occurred with other Masoneilan representative organizations. We are auditing the Manufacturer's representatives with a significant installed base of Masoneilan valves in Nuclear Power facilities in various geographical territories.

• Our concern is for the potential of other similar circumstances in Nuclear Power facilities.

Very truly yours, MASONEILAN-DRESSER INDUSTRIES W.T. Allen Quality Manager Masoneilan North American Operations WTA/mk cc: L.W. Kinderman J.E. Conway R. Cameron
