205SS Re: Oconee Nuclear Station Docket Nos. 50-269, -270, -287
Dear Sir:
Please find attached information concerning the performance of the Oconee Nuclear Station for the month of March, 1975.
In the review of data submitted in our operating status reports for 1974, several errors have been identified in the classification of unit shutdowns, i.e., forced or scheduled. These errors are summarized below:
1.
Oconee Unit 1 shutdown #1 which began 740101 is presently shown as a scheduled shutdown. The first 72.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> are, in fact, scheduled; however, the remaining hours were forced outage hours.
2.
Oconee Unit 3 shutdown #1 which began 741223 was shown and is a scheduled shutdown; however, the operating status sheet calculations were performed considering the outage to be forced.
The continued shutdown in January, 1975 is also considered scheduled.
3.
Oconee Unit 1 refueling outage which began 741019 should be considered a scheduled outage until 741227 at which time the refueling was completed. The outage from 741227 ti. 750311 was a forced outage for maintenance of reactor coolant pump seals.
The errors in classification of unit shutdowns resulted in incorrect unit forced outage rates for individual months, year to date, and cumulative to date columns. A tabulation of the correct figures as of December 31, 1974 is provided below:

The revised figures of unit forced outage rate for January and February, 1975 are provided on the attached revised data sheets.
