| description = Wolf Creek uses international standards organization, the solid contamination code, to measure the number and size distribution of oil particulates. Each number describes a particle size distribution and the particle count scale is logarithmic. Wolf Creek Procedure I-ENG-004, Lubricating Oil Analysis, Revision 3A, has an alert limit of greater than 18/15 and an action limit of 19/16. On August 11, 2011, the oil analysis results were 23/21. On August 15, after several oil exchanges and us of an in-line filtration skid, the oil was returned to the alert level of greater than 18/15. Subsequent oil analysis of the as-found oil by an independent laboratory confirmed the elevated particulates and elevated water concentration. Analytical ferrography found that the particles consisted of ferrous debris from normal rubbing, fatigue, spherical wear, and oxidation. Wolf Creek has since contracted with a vendor to determine the operability impact on the turbine and governor. The inspectors will review that analysis to close this item. Therefore, this issue is unresolved pending more inspection of the vendor analysis of the turbine: URI 05000482/2011004-04, Excessive Oil Contamination for Turbine-Driven Auxiliary Feedwater Pump. | | description = Wolf Creek uses international standards organization, the solid contamination code, to measure the number and size distribution of oil particulates.
