U.S. De artment of Energy Model to. ORNL Foamglas Docket No. 71-5795 Encl to 1tr dtd: MAY 0 51982 DRAWINGS Provide engineering drawings and specifications of the containment vessel (DOT Spec 2R) and the separate inner container required for I
plutonium in excess of 20 C1 (10 CFR 571.42).
STRUCTURAL 1.
Evaluate the performance of the seal ring bolt for the 30-foot drop test. The consequences of bolt damage, if any, for a drop onto the bolt must be considered in terms of any reduction in package effectiveness.
2.
Identify the orientations for the puncture tests. Justify that they represent the most damaging orientation. What effect would puncture impact onto the plywood disk have on the package?
CONTAINMENT 4
1.
Establish a containment criteria based on consideration of the package contents, and normal and accident conditions of transport.
Regulatory Guide 7.4 may be used.
2.
Show that the package satisfies the established containment criteria following normal and accident condition tests of 10 CFR Part 71.
3.
Show that the requirements of 10 CFR 571.42 are satisfied for plutonium shipments in excess of 20 C1.
OPERATING PROCEDURES, TESTS, AND MAINTENANCE Show that the sensitivities and testing schedules are adequate for safe use of the packages. Regulatory Guide 7.4 may be used for periodic testing. For assembly verification it is recommended that a test of sufficientsensitivitytolimitthemaximumreleasetoatypeAquantity in 10 jays is used, however, a leak test sensitivity greater than 1x1{
ata-cm /sec (air at 1 atm and 25'C leaking to a 10 gsitivity of 1x10~
atm-cm /sec, would not be required. The minimum se 3
at ambient) as i
specified in ANSI N14.5 should be met.
