- Model No. 884 Transport Package I
Docket ho. 71-9220 Encl. to ltr dtd:

, 1. The evaluation of the A-foot and 30-foot drop tests is based solely on comparisons to the Model No. 672 Jackage which was full-scale drop tested. However, the weight of t1e Model No. 672 package is about 40%
less than the weight of'che Model No. 884 package. Extrapolation of the Model No. 672 package drop test and puncture test date may not be valid. .
Show that the Model No. 884 package is adequately designed to meet both 1 4-foot and 30-foot drop tests, and the 40-inch puncture test, i 1 2. In accordance with 10 CFR Part 71, the Safety Analysis Report should be -
j revised to include reduced external pressure and increased external
- pressure requirements under Normal Conditions of Transport and immersion ;
i for all packages under Hypothetical Accident Conditions.
- 3. The Safety Analysis Report states that the tie-dewn devices can withstand '
the tie-down loads without compromising the structural integrity of the Model No. 884 package as demonstrated by the analysis for the lifting i l devices. Although the liftire devices are also used as tie-down devices, the lifting and tie-down loads are different as prescribed in 10 CFR 71.45.
It is not clear what part of the enalysis for lifting devices can be used i to demonstrate the adequacy of tie-down devices. Furthermore, the Safety :
Analysis Report did not address the consequences of failure of both devices ,
under an excessive load as prescribed in 10 CFR 71.45.
