SUMMARY
By application dated January 27, 1983, as supplemented, Automation Industries, Inc. requested approval for shipment of. an overpack for the Model No. 500-SU source changer. The source changer is approved for 120 ci of Iridium 192 in special form. This overpack permits the transport j
of 300 ci Iridium 192 sources by increasing the distance between the j
source and the accessible surface of the outer packaging during normal conditions of transport.
Based on statements and representations contained in the application, as supplemented, we have concluded the overpack and contents meet the requirements of 10 CFR Part 71, subject to the conditions contained herein.

DRAWING The package is constructed in accordance with Automation Industries, Inc. Drawing No. D-500SU-0P, Revision No.
DESCRIPTION Radiographic device within protective overpack. The overpack consists of an outer container which is a 15-1/8" diameter by 13-3/4" high, 18 guage drum and cover (MS-27683-30). Closure is provided by a 12 guage locking ring and lugs which is secured with a 3/8"-16UNC-3-1/4" bolt and nut.. The void space between the drum and radiographic device is filled with a tight fitting two piece molded hair pack.
The packaging (drum) is provided with four (4),1/4" vent holes. Maximum gross weight of the package is 80 pcunds.
CONTENTS (1) Type and form of material Iridium-192 as sealed sources which meet the requirements of special form as defined in 10 CFR.971.4(o).
(2) Maximum quantity of material per package 300 curies
~
DISCUSSION NRC Certificate of Compliance No. 71-9006 limits the maximum quantity of
)
Iridium 192 in the Model No. 500-SU source changer to 120 curies.
In order to ship in excess of 120 curies but not exceeding a maximum of 300 curies of Iridium 192 per package, the licensee is proposing that the Model No. 500-SU be encased within the overpack-drum.
However, when the maximum quantity of Iridium 192 for shipments does not exceed 120 curies, the licensee is proposing that the Model No. 500-50 still be shipped as is, viz, without the overpack-drum.
To demonstrate compliance with the structural requirements of Part 71, the licensee has submitted test results of the combination of overpack and the Model No. 500-SU source changer. This combination of overpack and the Model No. 500-SU have been designated as Model No. 500SU-0P by the licensee.
EVALUATION Model No. 500-SU by itself has met all the structural requirements of Part 71 as evidenced by the possession of NRC Certificate of Compliance No. 71-9006.
It does not need overpack-drum to provide additional structural strength. Tne primary function of the overpack-drum is to reduce surface radiation through geometry, viz, it provides longer distance between the outer surface and the source assembly. Hence, the overpack-drum only needs to be designed to retain the Model No. 500-SU within its cavity.
The licensee has conducted several mechanical tests to assure that the overpack-drum will retain the Model No. 500-SU under different operating conditions. These test results demonstrated that the new Model 500SU-0P does not have any problem when imposing lifting and tie-down loads on 4
it.
Hor does it have any problem after the package was subjected to the 4-foot free drop, penetration, compression, and puncture tests.
In all
,t of the above cases, the Model No. 500-SU remains inside the overpack-d rum. Although there was an earlier question concerning the performance of the seal ring bolt during the 30-foot top corner drop test, the staff subsequently concluded, based on a comparison with a similar package (Model No. 6717-B, NRC Certificate of Compliance No. 6717), that the 30-foot top corner drop test would not damage the seal ring bolt and thus cause lid separation which in turn would reduce the package effectiveness.
l l
f t
4 The revision includes an increase to 300 ci within the sealed source which increases the present ~1 watt internal heat source to'v2.5 watts.
The increased internal heat is not significant, and the increased heat path through the overpack is compensated by the increased surface area.
The overpack will in no way reduce the packaging effectiveness for the 1/2-hour fire test. The overpack has vent holes to provide for off gassing of the packaging material during the fire test. The proposed sealed source will, as now, meet special form requirements. Therefore, it is concluded that the requested amendment satisfies thermal and containment requirements of 10 CFR Part 71.
The shielding requirements for normal conditions of transport (49 CFR 6173.393(i))
will be met as denonstrated by actual radiation surveys prior to shipment as required by D0T regulations. Thesourcechanger(300cicontent) without the overpack was previously shown to meet the radiation requirement of 10 CFR %71.36(a)(1) for accident conditions of transport.
The applicant has provided detailed procedures for use of the package.
These were reviewed and found to provide adequate assurance that the Operating Procedures of 10 CFR Part 71 will be satisfied for the Model No. 500SU-0P packaging.
CONDITIONS 1.
The contents must be secured within a Model No. 500-SU radiographic source chan er (NRC Certificate of Compliance No. 9006, Docket No. 71-9006.
2.
Prior to each shipment, each vent hole shall be covered with a weatherproof patch such as duct tape or other similar waterproof-material.
CONCLUSION Based on our review, the statements and representations contained in the application, our previous approval of the Model No. 500-SU package, and the conditions listed above, we find that the Model No. 500SU-0P package meets the requirements of 10 CFR Part 71.
