.- ,1.1 CAROLINA POWER & LIGHT COMPANY SHEARON HARRIS NUCLEAR POWER PLANT UNIT NO. 1 INTERIM REPORT DECEMBER. 14, 1983 POTENTIALLY DEFECTIVE ENGINE-MOUNTED FUEL OIL LINES EMERGENCY DIESEL ENGINE GENERATOR SET ITEM 149 (DDR 2209)

REPORTABLE UNDER 10CFR50.55(e) AND 10CFR21

SUBJECT:

Shearon Harris Nuclear Power Plant Unit No. 1 10CFR50.55(e) and 10CFR21 Reportable Deficiency Potential defect with engine-mounted fuel oil lines on the emergency diesel-engine generator sets ITEM: Engine-mounted fuel oil lines of the emergency diesel-engine generator sets.

SUPPLIED BY: Transamerica DeLaval, Inc. , Oakland, California under CP&L Purchase Order NY-435079.

NATURE OF DEFICIENCY: Transamerica DeLaval, Inc. shipped two diesel engines to the Shearon Harris site in thy and June 1981.

In September 1983, Transamerica DeLaval notified CP&L that a potential problem existed with the engine-mounted fuel oil lines of the emergency diesel generator engines.

Excessive line vibration could cause the fuel oil lines to rupture, resulting in engine nonavailability and possibly fire in the Diesel Generator Building.

DATE PROBLEM OCCURRED: Refer to the above section.

DATE PROBLEM REPORTED: On October 24, 1983, CP&L (Mr. N. J. Chiangi) notified the NRC (Mr. A. Hardin) that this item was potentially reportable per the provisions of 10CFR50.55(e) and 10CFR21.

On November 18, 1983, CP&L (Mr. N. J. Chiangi) notified the NRC (Mr. A. Hardin) that this item is reportable per the provisions of 10CFR50.55(e) and 10CFR21.

SCOPE OF PROBLEM: The potential defect affects both energency diesel engines purchased on NY-435079.

SAFETY IMPLICATION: The diesel-engine generator sets supply power to the ESF buses in the event that both normal on-site and off-site power sources are lost.

The potential defect in the fuel oil lines could affect engine operation and possibly present a safety hazard.

~

, ..s REASON DEFICIENCY IS REPORTABLE: If lef t uncorrected, rupturing of the fuel oil lines could result in the loss of energency on-site AC power.

CORRECTIVE ACTION: A complete inspection of fuel oil line clamps and brackets will be mace using vendor-supplied drawings. Engine balance is to be checked and maintained. Mechanical Engineering will evaluate the fuel oil lines' installation and make a decision concerning the necessity of adding a spray shield as a fire preventive measure in the event of a fuel oil line rupture.

FINAL REPORT: Evaluation of the fuel oil lines and the balancing of the engine are projected to be completed by April 6,1984, at which time a final report will be submitted.
