9 SITJECT: Shearon Harris Nuclear Power Plant Unit No. I 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.

4 NATURE OF DEFICIENCY: Transamerica DeLaval, Inc. shipped two diesel engines to

- the Shearon Harris site in May and June 1981.

,a 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 due to improperly balanced fuel injection equipment could cause the fuel oil lines to

. rupture,- resulting in engine nonavailability and possibly r fire in the Diesel Generator Building, p - <

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

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

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

FINAL REPORT: Evaluation of the fuel oil lines shows that Engine IA-SA has the clamp and shield per the latest TDI drawing sent November 4,1983. The shield and clamp for Engine IB-SB will be installed by June 15, 1984. The engine vibration will be checked during start-up to determine properly balanced fuel injection equipment. The engine start-up is projected to 1xt October 31, 1984, at which time a

. final report will be submitted.
