Dear Mr. Giambusso:
In my letter of September 20, 1974, which proposed certain changes in the Oconee Nuclear Station Technical Specifications for operation of Oconee Unit 1, Cycle 2, I enclosed Babcock and Wilcox Report BAW-1409 which contained the supporting safety analyses. Certain typographical errors have been discovered in BAW-1409 since its distribution.
Please correct your copies of BAW-1409 by inserting the attached replacement pages.
Very truly yours,
