WASHINGTON, D.C. 20555-0001 March 26, 1997 rp,/dPZ MEMORANDUM TO: Denwood F. Ross, Chairman, CRGR Ashok C. Thadani, Associate Director, ADT:NRR Roy P. Zimmerman, Associate Director, ADPR:NRR Brian W. Sheron, Director, DE:NRR Gus C. Lainas, Deputy Director, DE:NRR Steven A. Varga, Director, DRPE:NRR Johns P. Jaudon, Director, DRS:RGN-ll FROM:
Charles E. Rossi, Dir Safety Programs Division Office for Analysis and Evaluation of Operational Data
SUBJECT:
SPECIAL STUDY, "OCONEE ELECTRICAL SYSTEM DESIGN AND OPERATION" This memorandum forwards the final report for AEOD Special Study, "Oconee Electrical System Design and Operation," for your information. The AEOD report documents an independent evaluation of the design and operation of the Oconee emergency electrical system, primarily based on operating experience. The evaluation was performed to assist the Committee to Review Generic Requirements in a review of this system directed by the Executive Director for Operations in August 1995. The efforts were initiated in the fall of 1995, and a draft of the report was issued June 1, 1996, based on information available at the time.
Technical comments from the Duke Power Company were used to correct and finalize the AEOD report. The report is intended to provide accurate descriptions of the operating experience and the design of the emergency electrical power system as it existed as of June 1996. It does not provide an evaluation of the electrical system as modified by changes after that time. Consequently, only information, analyses and testing which describe the electrical system as it was before June 1996 are contained in the AEOD final report.
Since issuance of the draft report, the Oconee station has initiated numerous activities including modifications to hardware and enhancements to operating procedures relating to the emergency power system. In early January 1997, Oconee also took advantage of a three unit shutdown to perform a series of tests of the emergency power system. The CONTACT:

D. Ross, et al.
-2 activities as presented to the NRC by Oconee address the concerns listed in the conclusions of the AEOD report. Satisfactory completion of those activities should resolve those concerns. Consequently, AEOD has no further recommendations regarding the Oconee emergency power system.
