Docket No. 50-206 Intake Structure Surveillance Guidelines San Onofre Nuclear Generating Station Unit 1

References:

1. Letter, M. O. Medford, SCE, to W. A. Paulson, NRC, dated October 18, 1984
2. Letter, John A. Zwolinski, NRC, to Kenneth P. Baskin, SCE, dated April 24, 1985 Due to the rebar corrosion discovered in the San Onofre Unit 1 intake structure in July 1984, plans to perform surveillance during future outages were established. The Reference 1 letter provided details of the repair program performed prior to return-to-service in 1984 and indicated that the guidelines for the long-term surveillance would be provided prior to the next refueling outage. Reference 2 provided the NRC's safety evaluation and also indicated that a surveillance program should be established. Enclosed with this letter is a copy of the guidelines that have been developed for this purpose.

The intake structure will be surveyed during the upcoming refueling /backfit outage.

If there are any questions on the enclosure, please let me know.

Very truly yours,
