i Suite 1217 Atlanta, GA 30303 SUEJECT: Reportable Occurrence (LER 78-062/017-0) Missing Seismic Pipe Restraint on Main Feedwater line Bear Mr. O'Erilly:

This is to confirm the notification made to Mr. A. E. Hardin by Mr. W. C.

Eairrton at approximately 1645 on September 22, 1978 regarding a possible condition, as described in Technical Specification 6.9.1.8.i.

On September 19, 1978, during an inspection of Class I and II pipe restraints and snubbers by Teledyne/hechtel/SCSI personnel as part of an NRC staff evaluation, it was noted that main feedwater line lateral seismic restraint FW-H49 was not in place. Joseph M. Farley Unit I was in cold shutdown at the time of the inspection. A review of on-site documentation was initiated to etermine if the restraint had been deleted or relocated. This review indicated that the restraint was in place prior to December 16, 1976. It was not determined when the restraint was removed. Concurrent with the documentation search, a preliminary seismic evaluation was performed by Bechtel indicating that the system may perform satisfactorily without the restraint. However, a more rigorous evaluation would have to be perfcrmed to verify this.

On September 21, 1978 Bechtel/SCSI notified the Plant Staff that the restraint was missing and no authorization could be located for its removal.

Further conversation with SCSI on September 22, 1978 indicated that a detailed evaluation concerning the need for this restraint would take one to three weeks.

Based on this estimate, Mr. Eairston called Mr. Hardin,. as noted above, to sahe him aware of this condition. -- -
