| | The purpose of this letter is to provide PP&L's final root cause evaluation of the RHR pump motor oil cooler failure which took place on May 28, 1990. |
| | The report concludes that failure of the 2C RHR Pump Motor Oil Cooler was not the result of Microbiologically Influenced Corrosion (MIC) nor was the pitting recent in origin. The cause of the pitting was Under Deposit Corrosion caused by manganese, iron, silt and sediment with some influence by microbiologic activity. |
| | Deterioration took place over a period of years. The rate of corrosion was influenced by such factors as heat, stagnation and velocity but the actual, unanticipated failure was the direct result of the lack of cleaning and inspection which would have provided the data needed to predict the life expectancy of the cooler. |
| | PP&L will ensure that the RHR pump motor oil coolers are replaced prior to the end of useful life. In addition, PP&L will evaluate replacement of the copper coils with materials which are less affected by the corrosion products present in the cooling water. |

| | In conclusion, we are confident that the actions described herein are conservative and adequate and therefore assure the continued safe operation of the plant. |

Director of Nuclear Reactor Regulation Attention: Dr. W.R. Butler, Project Director Project Directorate I-2 Division of Reactor Projects U.S. Nuclear Regulatory Commission Washington, D.C. 20555 SUSQUEHANNA STEAM ELECTRIC STATION FINAL REPORT ON RHR MOTOR OIL COOLER FAILURE Docket Nos. 50-387 PLA-3457 FILES R41-2 A22 7D and 50-388
Dear Dr. Butler:
The purpose of this letter is to provide PP&L's final root cause evaluation of the RHR pump motor oil cooler failure which took place on May 28, 1990.
The report concludes that failure of the 2C RHR Pump Motor Oil Cooler was not the result of Microbiologically Influenced Corrosion (MIC) nor was the pitting recent in origin. The cause of the pitting was Under Deposit Corrosion caused by manganese, iron, silt and sediment with some influence by microbiologic activity.
Deterioration took place over a period of years. The rate of corrosion was influenced by such factors as heat, stagnation and velocity but the actual, unanticipated failure was the direct result of the lack of cleaning and inspection which would have provided the data needed to predict the life expectancy of the cooler.
PP&L will ensure that the RHR pump motor oil coolers are replaced prior to the end of useful life. In addition, PP&L will evaluate replacement of the copper coils with materials which are less affected by the corrosion products present in the cooling water.

2 FILE R41-2/A22-7D PLA-3457 Dr. W. R. Butler This revision of the inspection requirements will take place by December 31, 1990 to allow preventative measures to be taken before the 10 year life of the replacement coolers is reached.
In conclusion, we are confident that the actions described herein are conservative and adequate and therefore assure the continued safe operation of the plant.
Very truly yours, H. W. eiser cc: NRC Document-Con. rol Desk (original, with Attachment)
