Application C' Model flo. IF-300 Packaging

!!cvenber 28, 1932 Ph Horizontal Oroy 1.

As shown in the internal shielding analysis, the 1.05 factor is only applicable to the cask in the region of the structural fins.

At the cask mid-length, a larger factor should be used.

Take into account that the amplification factor varies according to location, show that the' analysis of the spacer-disk has been based on naximum forces.

2.-

Jastify that the spacer-disk orientations will coincide with the cask orientations.

3.

Show that the holes in the disk for the poison rods has been deducted from the AllSYS llodel.

4.

Mcw-long were the plateau forces maintained in the dynamic analysis?

Show the effects on the spacer-disk deformations if the ar.alysis was based on the entire time-history of the forcing function.

5.

Justify the use of the fixed boundary.on the 270 degree sector of

,a if,E the spacer disk opposite the cask cavity wall interface.

Show.

thether the reaction forces at the nodal points indicate compression or tension.

6.

Provide an engineering sketch to show how the forces were applied to the A115YS finite element model.

4 7.

Provide maximum stress and deformations at key locations of the A

i spacer-disk finite element model.

i Vertical Drop 1.

Describe exactly what types of analysis has been perforned on the ADINA finite element model of the tie-rod (dynamic analysis, buckling analysis or dynamic buckling).

Provide engineering sketch of the finite element model and the applied forces.

Show results of the I

analysis.

2.

Justify the cask forcing tine-history can be directly used for the tie rod analysis without amplification.

3.

Provide an ar. clysis to show thet the s;&ccr-disk..ill nair.tain its axial location under the vertical crcp condition.

4.

Since the tie rod is continuous over nine spaccr-disks, show that the bending nonents produced by the inertial force of the spacers tre not accunulttive for the tie rod at the bottoa.

5.

For the botten drop, it is seen that the nuide channels will be impacted first and deform approximately three (3) inches before the tie rod contacts the impacting surface.

An analysis should be provided to evaluate the effects on the basket and the fuel rod h.ndles for this condition.

6.

Provide an analysis to show the spacer-dick with the cutouts for fuel cells and holes for poison rods provides adequate lateral constraint for the tie rod.

Corner Drog Provide justification for not considering the corner drop orientation in the fuel basket analysis.
