OCTOBER 31, 1984 POTENTIALLY DEFECTIVE ENGINE-MOUNTED FUEL OIL LINES EMERGENCY DIESEL ENGINE GENERATOR SET ITEM 149 NCR-84-390 REPORTABLE UNDER 10CFR50.55(e) AND 10CFR21
.c
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 energency 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 May 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 due to improperly balanced fuel injection equipment 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.
I 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 erergency 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.
y.*
I The potential defect of excessive vibration in the
[
fuel oil lines could affect engine operation and j.
possibly present a safety hazard.
l l
REASON DEFICIENCY IS REPORTABLE:.If left uncorrected, rupturing of the fuel oil lines if could result in the loss of emergency on-site AC power.
CORRECTIVE ACTION:
A complete inspection of fuel oil line clamps and i
brackets was made using vendor-supplied drawings.
Engine balance is to be checked and maintained, i'
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 is scheduled to be installed i
by February 13, 1984. The engine vibration will be i
checked during start-up to determine properly balanced fuel injection equipment. Due to increased Owner's Group inspections, the initial run of the engine is delayed until April 1985 through June 1985.
A final report is projected to be submitted by June 27, 1985.
