Drawing No. 133-1, Rev. 6 1.
The drawing should show the 1-inch thick x 24-inch square plate which is part of the lift / tie-down arrangement. The plate should be given a part number and listed in the Material List giving the number required and the material s,pecification.
The lift / tie-down pad has been renumbered as part no. 10a and.the pad m enting plate has been given part no. 10b and is listed in the parts list together with dimensions, material specifications and number required.
2.
The toroidal ring is not correctly shown in the half elevation of the cask. The picture should be corrected.
The drawing has been revised to show that toroidal ring obscures topof cask.
3.
The picture of the lift / tie-down lug does not agree with.the lug shown on-Drawing No. 138-1, Rev. 7 in that the lug appears to be thicker at one end chan the other. This discrepancy should be cc-rected.
~
The lift / tie-down lug is 4" thick for its entire length. The' detail-in Drawing No. 138-1 shows this fact more accurately.. Drawing No.
133-1 has been revised to show the correct attachment;of the lug to 5
the mounting plate and should show no discrepancy..
4.
Show that a shackle having a 2.75-inch screw pin, as called for on page 2.4-3, is dimensionally compatible with the. lift / tie-down. lug design
- considering the hole location relative to the 1-inch thick pad and the 1-inch fillet weld which joins the lug to the pad.
A nominal shackle size of 2 " will be used to lift the cask using a~2.75 inch pin., The outside diameter of.the shackle eye is Sh"...The 1 inch fillet veld willnot interfere with the shackle as shown on Drawing 138-la, a new dsawing, which is presented ~to show the shackle attachment..
-5.
The lid gasket dimensions (haterial List, Part No. 11) do not agree with the dimensions 'shown on Drawing No. 139-1.
Thelidgasket.dimensionshavebeenrevisedtoshowthefollow'ing, dimensions'-76.125" 1.D. x 80.875" 0.D. -x 1/8" thick. which agrees '

5.
Consideration'should be given in the size of the fillet veld which joins Part No. B-9, square tube, to Part No. B-1, outer shell. The relatively large fillet weld against the thin wall tube could cause unacceptable distortion in the tube cross-section, y
-The fillet weld requirement has been reduced to 1/8" in consideration of the thin wall of the tube. ~
