Dear Sir:

In accordance with the requirements of the Nuclear Regulatory Commission Title 10, Chapter 1, Code of Federal Regulations, Part 21, Cooper-Bessemer Reciprocating Products Division, a division of Cooper Industries, hereby notifies the Commission of a potential defect in a component of a DSRV and DSR Enterprise Standby Diesei Generator System.

There exists a potential problem with a Bellofram Air Cylinder, Cooper part number AJ-009-000 which is used to control a butterfly valve in the diesel engine intake air system. These air cylinders are installed on all nuclear Enterprise EDG's currently in service.

. OCG-10167 June 15,1995 On May 16,1995, a newly installed air cylinder failed at Grand Gulf Nuclear Station ,

on engine S/N 74033, during their refueling outage RF07, after fewer than 12 l actuations the left bank air cylinder piston / rod assembly separated which allowed the butterfly valve to go closed. With the left bank butterfly valve closed, the engine tried to maintain load with the right bank cylinders, which caused the right bank turbocharger to be overloaded and the EDG was shut down.

Inspection of the failed cylinder revealed that the piston / piston rod assembly had failed in the area where they were joined by projection welding. The root cause of this failure was a poor quality weld between the piston / piston rod.

Cooper-Bessemer has discussed this failure with the manufacturer of the air cylinder, Bellofram Corporation, and has reviewed their processes utilized in manufacturing and testing of the affected cylinder. Bellofram Corporation reports no known failures in other commercial applications of this type of air cylinder. Cooper-Bessemer also has no previously reported failures of this cylinder. Based on this information from Bellofram, Cooper-Bessemer has judged this failure to be an isolated incident, with no further corrective action required at affected utilities or at Cooper Bessemer.

Our investigation into this matter was concluded on June 12,1995. If you have any questions concerning this report, please contact Ronald G. Billig, Supervisor, Enterprise Engineering or John R. Schneider, Quality Assurance Manager at 412-458-8000.
