1 of 3 10 CFR50.55 (e ) FINAL REPORT ON DIESEL PUMP FOR FIRE PROTECTION FOR WOLF CREEK GENERATING STATION, UNIT NO. 1 KANSAS GAS AND ELECTRIC COMPANY MARCH 21, 1983
J Attachment to KMLNRC 83-028 2 of 3 I.
INTRODUCTION During startup testing of the Wolf Creek Generating Station (WOGS) diesel fire pump, an oil leak developed in the hydraulic governor tubing where a steel tube connects to the governor. The diesel fire pump is the backup pump for the fire protection system.
Although the system itself is not safety-related, it is considore.1 to be a special scope system.
II.
DESCRIPTION.OF DEFICIENCY Startup personnel had determined that the oil leak was a result of a split in the tube flare.
This split developed as a result of improper flare fabrication.
Further investigation also revealed that the flare fitting nut was made of brass whereas other flare fitting nuts were steel.
The brass nut was thought to be inadequate for setting the steel flare.
However, the vendor indicates that ei ther brass or steel fitting nuts are acceptable.
III. ANALYSIS OF SAFETY IMPLICATIONS As indicated above, the diesel fire pump is a backup pump for the fire protection system.
This fact makes it difficult to determine the safety implication of this deficiency.
Therefore, ra ther than performing a safety analysis, the conservative as sumption was made that this deficiency could have adversely affected the safety of operations of the plant.
This matter is therefore reportable under 10CFR50.55(e).
.x Attachment to KMLNRC 83-028 3 of 3 IV.
CORRECTIVE ACTION All governor tubing will be. replaced with new ' tubing.
We tubing will have double flare ends.
%ese tubing flares will conform to SAE Standard J-533 and will be installed using steel flare fitting nuts.
It is anticipated that approximately three months will be required to complete the corrective action' In any event, :the corrective action will'be completed prior to fuel load.
