Gentlemen:

The following is' provided in order to keep you informed as to our progress in satisfying the requirements of IE Bulletin 79-02.

We have completed our CEB load analysis assuming flexible base plates for AN0-1. A total of 37 supports having safety factors of less than 2 were identified. These have been corrected to within the bulletin specificar. ions. A total of 82 supports have been identified with safety factors greater than 2 but less than the safety factors requi ed by IE Bulletin 79-02. These will be processed as indicated in our vuly 6, 1979 letter.

The support analysis for ANO-2 is not complete at this time due to the manpower limitations resulting from our IE Bulletin 79-14 effort. We will provide you with results from this analysis September 1,1979.

All supports with safety factors of less than 2 identified to date have been ccrrected.

Very truly yours, E M b kh David C. Trimble Manager, Licensing DCT:M0W:nak
