Jr p Revision September 12, 1978 Loads.from the lifting lugs are distributed to the secondary lid where they are reacted by the eight 1 inch diameter Grade 5 studs.

The secondary lid must react these loads by plate bending.

From the sketch below it can be seen that the bolts tend to "fix" one end of the plate while the attachment to the two 4 inch plates provides the other I

fixity.

1.6.6 Free Drop The Model CN6-80B package with payload weighs 57,500 lbs.

Appendix A.6 of 10 CFR 71 prescribes a drop height of one (1) foot for packages in excess of 30,000 lbs.

The overpack, designed to protect the cask under a 30' hypothetical free drop, effectively

- cushions and protects the cask from all " normal" free drop effects.

None-the-less, for additional conservatism, the analysis present in the Type "A" submittal for the CN6-80, as.found in Section 1.6.6, page 1-13 through 1-19, demonstrates the adequacy of the cask to survive a one (1) foot drop by itself (without any assistance from the.overpack).

9 The overpacks are attached to the cask body by means of 8-1 inch diameter bolts.

Flat end drop condition will place the over

]

pack in direction compression.

The attachments will not experience loading.

For the side drop condition tolerances around the attachment fixture allow the overpack to shift slightly until it can react loads in direct compression.

1.,

e

=m

Revision 1 September 12, 1978 From the figure below it can be seen that the corner drop condition will produce a negative rotaticn, or compression load, on the overpack.

Again for this condition the at-i tachments remain essentially unloaded.

Therefore, it can be concluded that the overpack will not produce loads on its attachments that will effect its ability to meet other nections of 10CFR71.

Therefore, it can be concluded that the studs will not shear out prior to developing their full tension capability.

i From the print out shown on page 1-43, column 9, it can be seen that 90% of the impact area is experiencing a compressive stress between 4000 psi @ 70% strain and 1000 psi @ 7% strain.

The 10% is experiencing compressive stresses greater than 4000 psi.

~. - -

Revision September 12, 1978 This number is conservative since the average compressive stress acting across the lid face will be substantially greater than the nominal 2000 psi assumed here.

The higher foam compressive stress reduces the load that must be reacted by the primary studs.

Secondly, the effective area will be considerably larger than that assumed.

Foam does have the ability to distribute loads out over a larger footprint.

This will also increase the load carried by the overpack.

Thirdly, a major portion of the overpack weight will be reacted directly onto the impact surface thus reducing the load experienced by the primary studs.

Each stud is threaded into the top closure ring and high j

strength doubler.

Total thread engagement includes.75 inches for the closure ring and 1.75 inches into the doubler.

Recommended thread engagement is that equal to the thickness of a heat treated nut of the smme tensile strength as the stud.

Minimum thickness for a 1 1/4 NC Heavy Hex Nut is 1.250 in. (Max.), per Machinery Handbook.

Since the doubler is manufactured frem a material of greater strength than the stud, the following conservative margin of safety can be calculated.

Lateral or shear loads resulting from the corner drop condition are reacted by the deep stepped lid.

The two lid plates are tied

?

l together by way of two welds with'a total capacity of:

{

Margin of Safety M.S. = 3,644,500/3,288,000 -1 M.S. = +.11 t

Therefore, the stepped lid can safely react all lateral loads resulting from corner drop impact conditions.

1.7.1.3 Free Drop Impact. Analysis, Side Drop Detrimental effects resulting from a side drop are limited to the closure areas.

Both primary and secondary lids are deeply stepped and manufactured from" solid steel plates.

lid are'not required to react this shear force since the radial i

j clearance with their hole is greater than that of their stepped i

lid..

i.e.,

lid bottoms out before bolts contact.

In order to determine the amount of deformation that would be experienced by a. side impact it was conservatively assumed that i

j only the projected length of the cask on the overpack would be j

l effective.

Therefore, the overpacks effective length would be 44 1

i inches.

i-l The impact acceleration forces are determined by use cf a NUPAC l

developed computer program called SYDROP (Side Drop - Cylinders).

SYDROP was developed to. consider the strain hardening in a crushable c

foam overpack.

aevision - 1 September 12, 1978 those discussed in Section 1.7.1.2 for the corner impact program CYDROP.

Two cases are analyzed - minimum foam properties and maximum foam properties given in Figure 1 of Section 1.3 above.

Key results are sammarized below with computer results following:

Energy Deflection Absorption Impact Case (in)

Margin Acceleration Minimum Properties 10.0

+0.53 108.6g Maximum Properties 9.5

+0.95 101.7g

• Interpolated at KE=SE.

As for the corner impact case, the impact acceleration values are relatively independent of material properties but show a tendency for slightly higher final impact accelerations with the " softer" minimum properties cases.

In an effort to evaluate the effect of that part cf the over-pack that extends beyond the end of the cask an additional SYDROP run was made.

For this case the effective package length was assumed to be equal to the total length of both overpacks.

Revision 1 September 12, 1978 From the print out it can be seen that the maximum deformation will only be 7.75 in. vs. 9.25 for cask No.

1.

Also the maximum acceleration at the end of the impact stroke is 99 g's vs.

108.6 g's.

(Ref. pg. 1-4 4, a)

Therefore, it can be concluded that the overhanging section of the overpack will absorb some portion of the energy.

It is conservative to neglect this contribution and use the maximum acceleration figures calculated and referenced above.

As noted earlier, the secondary lid bolts do not react these shear leads due to the stepped lid design. The following analysis is provided to demonstrate what margin it safely would exist if they were required to react these loads.

Lead per bolt is:

P=

(2000 lbs Lid) (109 g' ci/8 bolts P = 27250 lbs (she ar )

Bolt capac_ty is:

R=

(115,000 psi) (. 563 in ) (60%)

R = 38847 lbs 1-45

From the drawing and the sketch below it can be seen that the lid

_t

' is flush with the outside diameter of the cask.

Lateral._ loads from the lid are reacted in direct bearing on the 4 inch thick plate while 4

j lateral loads from the cask body are distributed along its length.

Therefore, the actual shear loads carried across the joint for side drop conditions are very small.

They become limited primarily to acceleration loads of the inside lid plate on its attachment welds to the outside plate.

Conclusion:==

From the above it can be concluded that under the most conservative conditions the package will maintain 3 inches of foam in the com-pressed area.

Impact loads will not produce detrimental effects on closure system since all loads are carried in direct compression across the deeply stepped joints.

Therefore, the side drop of 30 feet will not produce detrimental effects to the package.

Revision 1 Sepember 12, 1978 From Fig. 2.3 of the ORNL-NSIC-68 on the following page, it can be seen that two test points for carbon steel fall below the established design curve.

If a line was drawn between these two points it would produce an E/S ratio of 35 for a 1.0 inch thick plate.

Using the package energy level the required mechanical properties of the external skin should be:

E/S = 35 S = E/35 (57500)(40)/35

Revision 1 September 12, 1978 End impact evaluation of the'CN6-80B package is based upon a detail non-linear finite element analysis which conservatively assumed only one of the two lapped end plates deformed inelastically to absorb the full kinetic energy of impact.

That is, the energy absorbed by the smaller second plate was conservatively ignored.

The CN6-80B evaluation employed an axi-symmetric "ANSYS" finite element solution which considered both large deflection of the circular plate and bi-linear characteristics of its mild steel material.

The CN6-80B evaluation model consisted of 52 nodes and 36 iso-para-metric quadrilaterals (STIF42) representing an axi-symmetric plate i

of four inches thickness and 68k" in diameter, as shown in Figure 1.7.2-1.

The plate model was loaded by applying a series of pre-scribed displacements at a location corresponding to the contact perimeter of the 6" diameter puncture pin.

At the outer diameter of the plate, the forces induced by this prescribed displacement were reacted in an axial fashion.

No radial constraints were imposed upon the model except at the axis of symmetry. The con-ventional bi-linear properties of mild steel used in this analysis corresponded to a 36 ksi yield and 58 ksi rupture at a conservative 10% strain-value.

The st..ctural behavior of the plate at maximum pin penetration is shown in Figure 1.7.2-2.

Figure 1.7.2-2 illustrates both deformed

-plate shape and effective strains for each of the 36 finite elements.

1-49

...~ --.

I l

R@ vision 1 September 12, 1978 orr an ef fective ' strain basis, the worst severely strained element possesses a rupture margin of greater than + 1.13; thus, no puncture occurs.

Maximum pin penetration (deformation of plate) was determined by plotting the load deformation characteristics of node.2 (the

- i puncture pin diametrical location) as shown in Figure 1.7.2-3.

Integrating this load-deformation relation, as shown in Figure

]

1.7.2-4, produces a description of plate strain energy versus i

deformation depth.

The kinetic energy relation of the dropped cask is also plotted on figure 1.7.2-4.

The intersection of these two energy relations defines the defomation depth at which the strain energy (or work done on the plate) equals the available kinetic energy.

At this deformation depth, 2.48 inches,-the deformation is arrested and can proceed no further.

Frem Figure 1.7.2-3 the maximum load will be:

F=2n (188,000 lbs) 6 F = 1.18 x 10 lbs For puncture conditions directly on the lid, loads would be trasmitted from the secondary lid to the primary lid by way of the seal spacer block.

Compressive stress on the block is calculated as follows:
