(psi), was also changed in all three places.in the second column from 27.9 x 106 to 27.6 x 106 to reflect the value at 200*F rather-than 150*F.

2. Page 7-3: Tha value of E was changed'to 27.6 x-106 in the ninth line of the second paragraph. In the equation for the limiting vertical compressive stress, 6cr, at the beginning of the third paragraph, the value has been changed from 14,387 psi to 14,232 psi.

3. Page 7-4: In the sixth line under Section 7.4, a parenthetical insert was added to indicate the use of SA 36 material for the. impact shield.

4. Page 7-6: The maximum veld shear stress, rmax, was changed from 15,684 to 15,515 psi, to reflect the previously mentioned al percent change.in E.

These revisions were discussed with morrhers of your staff on April 23, 1992, and do not have significant-effect on any previous analysis or calculation performed.
