2. Letter from R. Gridley (TVA) to NRC, "BFN - Seismic Qualification of Drywell Steel - (NRC TAC No. 00302)," dated April 28, 1988. l A. Enclosure 1 and Table 1 of Enclosure 1:
1. 3rd sentence of Item 2 under Resolution Section - How were these ' j loads generated and applied to the platferm model? -
2. Items 3, 5 and 6 under Resolution Section - If modifications .

are needed as a result of evaluation, why are the interim operability criteria instead of long tenn criteria for design criteria) to be used for the design of modifications.

3. Licensing Issue - Provide basis for changing the factor "1.6" to "1.7" (References 1 and 2).
4. Item 3 of "Justification" -

(i) HRC NUREG-0800, "Standard Review Plan," was issued after 1 BFN was licensed. It is the staff's position that this i document should be used as a whole package instead of piece l by piece. i (ii) The staff treated the Mark I Torus Long Term Integrity Program as a case by case evaluation. T refore, the ,

criteria accepted under this program a pplicable for '

other evaluation, e.g., BFN Seismic Design Program.

5. Table 1 -

(i) The allowable stresses for steel and weld are given as a range because of the use of "up to." Specific allowable stresses should be explicitly defined for each of different load cembinations to be considered in the re-start evaluation.

(ii) The "Similar to" in the temark for the concrete anchor criteria is unspecified and should be clearly defined.

(iii)What are the allowables for steel members under t w pression and bending.

(iv) What are the allowable tension and shear stressss for bolts.
