Diesel Low Fill Procedure Standard Review Plan (SRP) 9.5.7 " Emergency Diesel Engine Lubrication System" states in part that "the system has been designed to preclude the entry of deleterious material into the system due to operator error or.
extreme natural phenomena during recharging or normal operation.
In 1980 a nuclear power plant incident occurred that required the addition of lubricating oil to a diesel engine while it was operating.
The normal fill connection could not be used when the engine was running, and the D/G technical manual indicated lubricating oil could be added with the engine in operation but did not describe how it could be done.
As a result, plant personnel added five barrels of oil to the D/G without indication of an increase in engine sump oil level. - After engine shut down sump level was restored to normal after adding two more barrels of oil.
Investigation by plant personnel assisted by the D/G factory representative revealed that the five barrels of lube oil were added to the diesel engine air box through a mismarked drain connection. The lube oil was drained from the air box and the D/G was satisfactorily operated.
During the investigation the D/G factory representative noted that T
procedures for adding lube oil to the diesel engine were not available and that personnel performing this task were not familiar with, nor trained, on how to add lube oil to a running engine or how to verify that oil had been properly added.
As the result of this incident the NRC Headquarters Office of Inspection and Enforcement issued IE Circular 80-05 " Emergency Diesel Generator Lubrication Oil Addition and Onsite Supply," dated April 1, 1980, which included in part the following recommendation
" Verify the existence of adequacy of procedures or instructions for adding lubricating oil to safety related equipment. These operating procedures or instructions should be available locally in the area of the affected equipment."
The staff's concern is that if operating procedures are not located or posted in the D/G room, lubricating oil might be added to the D/G without consulting the procedures and thus potentially compromise the availability of the D/G.
For the above reasons, the staff requires that operating procedures are either located or posted in the D/G rooms as has been done in similar installations previously approved by the staff.
