i Description of Defect or Non-Compliance By Gimpel's design, the secure attachment of the coupling, item (2 9) on Gimpel drawing P-2989, to the stem, item (28), is assured by spotting the valve stem with a .25 drill .125 deep after proper location is determined at assembly. The set screw is then threaded into the coupling until it seats in this spot and then staked in place. The original valve stem at Davis Besse unit 1 was not spotted to receive the set screw and the setscrew was locked in the coupling and not making contact with the stem.

Safety Hazard Created or Non-Compliance i

When the coupling is not properly locked to the stem, the stem is able to rotate and unthread from the coupling. The valve is then inoperable and the safety related function of the turbine is compromised.

Number and Location of all such components that could contain this defect The only site that has reported this defect is Toledo Edison at the Davis Besse site. Pages 3 to 9 list the turbine S/N and location of all known Gimpel T&T v*.lvss in Nuclear Applications that could experience this problem.

1 Corrective Action l i 1. Dresser-Rand has changed the Nuclear Part Inspection Records for both the coupling and the stem to require that these parts be tagged with the proper assembly instructions. (See Appendix for samples)

2. The Nuclear Part Inspection Records for the couplings were also changed to verify the set screw hole is tapped fully through.

3. Dresser-Rand Quality assurance will implement a source inspection requirement for all future Gimpel T&T valve orders or verify this assembly is correct at D-R source inspection. Existing Nuclear Part Inspection Records for complete valve assemblies are revised to call for this inspection.

Advice to Customer All Utilities should immediately do a visual inspection of the thread engagement of the stem to coupling to determine operating status of valve. This should be followed by a disassembling and inspection of the coupling and valve stem. The inspection should verify all of the following:

1. The valve stem has been spotted for receiving the set screw

2. The set screw can be threaded through the coupling and engage l the stem.

3. The setscrew is securely seated in the drill spot when assembled.

4. The setscrew is adequately staked in place to prevent it from backing out.
