'o Sublect: ~
Shearon Harris Nuclear Power Plant Unit No.1 -10CFR50.55(e) and 10CFR21 reportable deficiency concerning the crankshaf t oil plugs for the IB-SB Emergency Standby Diesel Generator.
Item:
The oil plugs in the cra'nkshaf t for the IB-SB Standby Diesel Generator (S/N 74047)
Supplied By:
The crankshafts ' were supplied with the Engines by Transamerica Delaval, Inc. (TDI), Oakland, California a
Nature of Deficiency:
In a letter dated March 18, 1985, TDI informed CP&L of a potentially reportable problem with crankshaft oil plugs made of 22 gauge metal. After investigation CP&L determined that the IB-SB engine had 22 gauge plugs in the crankshaft.
Date Problem Occurred:
Refer to section above.
Date Problem
)
ReDorted:
On April 12,1985, Mr. N. 3. Chiangi (CP&L) notified the NRC (Mr. A. Hardin) that this item is reportable under the provisions of 10CFR50.55(e) and 10CFR21.
Scope of Problem:
. This' problem concerns 16 oil plugs installed on the IB-SB engine.
Reasons Deficiency Is Reportable:
The emergency diesel generators supply on-site power to essential systems in the event of a loss of off-site power.
Proper operation of the lubricating oil subsystem is essential to the operation of the diesel generator. Loss of one or more of these oil plugs could lead to loss of oil pressure and resultant unavailability of the diesel generator.
Corrective Action:
In April 1985 TDI representatives replaced the 22 gauge crankshaf t oil plugs with 16 gauge oil plugs. This work was checked by CP&L Engineering and QA personnel. The final acceptance was based upon a liquid penetrant examination of the new oil plugs performed by CP&L NDE personnel.
Final Report:
The new 16 gauge oil plugs have been installed.
