Docket No. 71-6581 JUL 0 71980 Encl to ltr dtd:
1.
The discussion in Section 10.1.2.2 (page 10-6) is not adequate to show that the aluminum clips are acceptable for the following reasons:
a.
The text does not provide a sketch or otherwise clarify that the aluminum clamps were loaded for the load-deflection test (Figure 10.1) in the same manner as they would be loaded under accident conditions when installed in the container.
b.
Figure 10.1 does not show that an aluminum clamp can develop as large a resisting force as a steel clamp.
c.
Figure 10.1 does not show that the energy to deform an aluminum clamp is as large as the energy to deform.a steel' clamp.
d.
Figure 10.1 does not show that an aluminum' clamp can deform as much as a steel clamp without failing.
e.
The text doet not show that the clamps are adequate for the fire test.
2.
Provide a table which shows the minimum number of separator blocks, full clamps, shock mounts and restraining bars that will be utilized for different strongbacks and for various types of fuel in the Model 51032-1 and the Model 51032-la packages.
