Encl. to ltr. dtd.:
Contents Section 1.2.4, " Contents of Packaging", states that the maximum radioactivity present in a package is 45 mci.
The table of maximum radioactivity shows 42.7 mci per package.
Correct this discrepancy.
Provide calculations which show that the radioactivity listed in Section 1.2.4 meets the requirements of low specific activity, as defined in 10 CFR 671.4.
Structural 1.
The packaging description states that the closure uses a black neoprene 0-ring gasket.
Revise Drawing No. 000-M0075-B to show that the gasket is a 3/8-inch 0-ring made of smooth black neoprene.
2.
Three different types of closure were tested for the package.
Verify that the drum that passed the normal condition tests is identical to the drum shown on Drawing No. 000-M0075-B.
Provide records and photographs which show the damage and condition of the package following the tests.
3.
The contents of the test packages were non-radioactive material.
Provide the basis for the conclusion that there is no significant increase in r
radiation levels or substantial reduction in the effectiveness of the test specimens.
4.
The void spaces in the test packages were filled with sand, which could provide a cushioning effect. Show that the test packages adequately and conservatively represent the actual package.
5.
Specify the weight of the test packages. Note that the weight of the e
test packages should be greater than or equal to the maximum weight of a loaded package.
6.
Drawing No. 000-M0075-B specifies a maximum package weight of 282 pounds; however, Section 4.6 of the application specifies a maximum package weight of 333 pounds.
Correct this discrepancy.
Containment j
l.
The two drums initially tested for increased and decreased external pressure conditions failed the tests. Justify the conclusion that the i
package is capable of withstanding the test conditions, when only one of three drums tested passed the tests. Describe the tests, inspections, i
and determinations that will be made prior to each shipment to ensure that the package is properly sealed, such that the package can withstand the increased and decreased external pressure conditions.

Describe in detail any damage that was caused to the containment system of the package by the free drop tests.
Include photographs which show that the containment system of the package remained sealed following the free drop tests.
3.
Filling the void spaces in the drum with sand during the drop tests could provide a cushioning effect for the waste materials within the drum.
t' Show that the compacted materials and any non-compacted materials to be shipped would not pierce the thin (20 gage) metal drum body under the four-foot drop test conditions.
Operatino Procedures 1.
Revise the operating procedures to specify the steps that will be taken to assure that the activity in the package does not exceed the LSA limit (see step 4.8.3, Section 4.8 of the application). Also, discuss how the contents will be repackaged if the activity exceeds the LSA limit.
2.
Revise the operating procedures to include the tests, inspections, and determinations that are made prior to each shipment to ensure that the l
package is properly sealed.
