Certificate of Compliance Application for 40 Gallon Container Model No. 40G-A Rev.1 (06/30/93) 1 GENERAL INFORM ATION
1.1 INTRODUCTION
The package for which this certificate of compliance application is made is to be used for exclusive-use shipments by highway of low-level radioactive waste which has been generated in the decommissioning of the former mixed oxides plutonium facility at Nuclear Fuel Services, Inc. (NFS), Erwin, Tennessee. Each shipment consists of up to 100 packages, each containing approximately 38 mci, and a total shipment activity of about 3.8 Ci. Five to ten shipments will be scheduled from the NFS facility to the Scientific Ecology Group (SEG) facility in Oak Ridge, Tennessee. The model number which has been designated to the package design is 40G-A.
It is an example of a package type which is commonly referred to as an "NRC-Certified LSA Greater Than Type A Package".
1.2 PACKAGING DESCRIPTION 1.2.1 Packaging Configuration Figure 1 depicts the package which is a 40-gallon,20-gauge carbon steel, open head drum, 36" high and 18%" diameter, with a conventional bolted ring closure. It utilizes a half-round tubular, smooth, black neoprene gasket. The waste material originating at NFS has been previously compacted at NFS into 16"X 16" bales of varying thickness ranging from 2-10 inches. Each waste item is triple wrapped with plastic to enhance contamination control measures. Two to four of these bales are J
packaged into the 40-gallon steel drum which, after loading, does not exceed a weight of 333 pounds. These drums are then shipped to SEG for additional compaction. At SEG, the 40-gallon drums are compacted and packaged into a 110-gallon stabilized drum (Model 110G-A) for shipment to Chem-Nuclear Systems, Inc. as Class C-Stable waste.
The containment system of the package is considered to be the entire drum, including the lid, gasket and locking ring.
l.2.2 Packaging Snecifications The package is tested by the manufacturer to meet the requirements of a DOT Type A package and the criteria for a DOT Specification 17H steel drum. Each drum is-subjected to 5 psi internal air pressure. Random samples are taken every four months for 15 psi hydrostatic pressure testing for five minutes, filled to 98% with water, and dropped from a 4' height onto solid concrete so as to strike diagonally on the chime.

Certificate of Compliance Application for 40 Gallon Container Model No. 40G-A Rev.1 (06/30/93) 1.2.3 Onerational Features There are no complex operational features of this package. To assure containment at decreased or increased external pressure, only new drums and gaskets are used.
Quality control measures are implemented to assure that the gasket is firmly seated and correctly positioned and that sealing surfaces of the lid and top rim of the drum are smooth, clean and free of particulates which might inhibit containtnent of differential pressure. The closure ring is tightened to 40 i 4 ft-lbs while tapping the ring with a rubber mallet to ensure the gasket seats completely on the drum.
1.2.4 Contents of Packaging The radioactive contents of the package consists of dry solid waste material oflow specific activity generated in the decommissioning of a mixed oxide plutonium-uranium fuel fabrication facility. The maximum radioactivity present in any package shall not exceed 38.4 mci, based on a 300 pound waste content at the upper limit of radioactivity for LSA as determined by 10 CFR 61.55. Gross payload weight shall not exceed 333 pounds. The isotopes and respective activity values are shown in the following table:
Isotopic Content of Typical 40 Gallon drum Radionuclide millicuries Uranium 233 5.17e-01 Uranium 234 5.44e-02 Uranium 235 6.94e-04 Uranium 238 3.88e-03 Plutonium 238 2.16e+ 00 Plutonium 239 4.43e+ 00 Plutonium 240 1.86e+ 00 Plutonium 241 2.50e+ 01 Plutonium 242 9.70e-04 Americium 241 4.43e+ 00 Total Activity:

Gloveboxes are removed for decommissioning on a batch basis and moved to the decontamination and volume reduction facility. Once in the facility, samples of j
contamination present in the glovebox are removed and assayed with gamma i
spectroscopy to determine uranium and plutonium isotopic ratios. The glovebox is decontaminated and compacted for volume reduction. The fissile content of the compacted waste is determined using a passive-active neutron (PAN) non-destructive i
assay (NDA) system. The isotopic ratios are applied to the PAN NDA value for assignment of activity per isotope present. Each waste item is weighed and i
radioactive concentration is determined. All waste items associated with the batch are assigned the batch isotopic mixture. All information relative to the waste item is stored in a computerized material tracking system. Waste items are then stored on waste shelves awaiting final packaging.
Final packaging is accomplished by selecting those waste items from the computer data base which, when packaged into the 40-gallon drum, do not exceed the criteria for LSA waste. The formula for determining LSA concentration is:

Due mainly to the 2 mci A limit for 23'Pu, the sum of the ratios of each constituent i
2 divided by its individual A value generally exceeds unity. Therefore, the activity j
2 mcy be greater than A Per package, but at concentrations which are within the 2
limits for low specific activity for purposes of transportation. The material is i
classified as Class C pursuant to 10 CFR 61.55.
The typical range of radiation levels is 0.1-0.5 mrem /hr at the surface of a loaded package and 0.01-0.05 mrem /hr at one meter from the package.
2 GENERAL STANDARDS FOR ALL PACKAGING 2.1 MINIMUM PACKAGE SIZE No dimension of the package is less than 10 cm. (four in.)
2.2 TAMPERPROOF FEATURE Each drum closure is equipped with a conventional wire seal which passes between the locking ring bolt loops. Opening of the drum is not possible without destroying the
.l integrity of this seal. An intact seal is evidence that the package has not been opened by unauthorized persons.
j 2.3 POSITIVE CLOSURE
]
The closure mechanism consists of a conventional locking ring and threaded bolt closure.
It constitutes a positive closure which can be securely closed and which cannot be opened inadvertently.
j 2.4 CHEMICAL AND GALVANIC REACTIONS There are no materials of construction within the package which will create significant 1
chemical, galvanic, or other reactions among the packaging components, or between the packaging components and package contents, or as a result of in-leakage of water to a maximum credible extent.
2.5 LIFTING AND TIEDOWN STANDARDS FOR ALL PACKAGES 2.5.1 Lifting Devices -
No attac' mts will be made which form a structural part of the package and'which could N tuec as lifting devices. Lifting and transfer of the packages will be by fork truck vehele and conventional drum lifting attachments on the vehicle forks 5
Certificate of Compliance Application for 40 Gallon Container Model No. 40G-A Rev.1 (06/30/93) which grip the sides of the package, the use of lift slings which grip the top of the packages or the palletizing of packages on wooden pallets.
t 2.5.2 Tiedown Devices There are no devices that are a structural part of the package which might be used as tiedowns. Tiedown and securing of packages to preclude shifting within the transport vehicle will be by construction of conventional wooden shoring as needed along sides, top, and ends of the load, and along outer bottom edges of the rows of packages.
2.6 NORMAL CONDITIONS OF TRANSPORT (71.71)
The package has been tested and assessed against the applicable requirements of 10 CFR 71.71 and also the applicable standards of 10 CFR 71.41 through 71.47. Based on the results of this testing and evaluation, it is concluded that under the tests for normal conditions of transport, there will be no loss or dispersal of radioactive contents, no significant increase in radiation levels, and no substantial reduction in the effectiveness of the packaging.
Package qualification testing is reported in " Qualification Testing on Two 40-Gallon Drums", Wyle Laboratories Report No. 42488-01, May 1992, " Qualification Testing on j
110 Gallon Overpack and 40 Gallon Drum", Wyle Laboratories Report No. 42977-01, i
November 1992, and " Qualification Testing on Two 40-Gallon Drums", Wyle Laboratories Report No. 43396-01, June 1993. The contents of the test specimens were j
non-radioactive materials of the same or similar waste matrix processed and assembled as described in Section 1.2.1. Sand was added in the void spaces around the compacted bales to detect loss of containmer.t. The June 1993 test was conducted without sand to demonstrate that sand had no cushioning effect on the contents during the drop test. The following table summarizes results of all tests performed.

Certificate of Compliance Application for 40 Gallon Container Model No. 40G-A Rev.1 (06/30/93)
The following sections provide a brief description of the tests for normal conditions of transport (10 CFR 71.71) and the results.
2.6.1 Comoression Test 71.71(c)(9)
A continuous compressive load of 1,400 pounds (over four times the package weight) was applied to the top of the package for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
RESULTS: After 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, inspection of the package revealed no anomalies. The package passed the compression test.
2.6.2 Water Sorav Test 71.71(c)(6)
A specimen package was subjected to a water spray environment simulating two inches of rainfall per hour. There was no evidence ofinleakage of water into the package.
RESULTS: ne package passed the water spray test.
2.6.3 Vibration Test 71.71(c)(5)
The package was placed on a vibration table, with a small holding fence built around it to restrain horizontal motion. The vibration table was operated at a frequency of 182 rpm, which caused the package to be continuously lifted from the floor of the table such that a 10-gauge stect strap could pass between the package and table. The package was vibrated for one hour at ambient temperature. Upon inspection, no anomalies or evidence of loss of contents were detected.
RESULTS: ne package passed the vibmtion test.
2.6.4 Penetration Test 71.71(c)(10)
A 1-1/4" diameter steel rod cylinder with a hemispherical end, weighing 13 lbs. was dropped over a distance of 40 inches, through a steel guide tube sleeve, such that the hemispherical end of the rod struck perpendicular to the top, bottom and sides of the package. Three strikes were performed on each of the three surfaces. There was no evidence of leakage, loss of contents or other anomalies.
RESULTS: The package passed the penetmtion test.
2.6.5 Thermal Tssts 71.71(c)(1) and (2)
The package was placed in a thermal chamber and tested to the 100* F High.
Temperature Test for 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The package temperature was then reduced to 9
i 2
Certificate of Compliance Application for 40 Gallon Container Model No. 40G-A Rev, I (06/30/93) ambient. After reaching ambient temperature, the package was ther. exposed to a low temperature environment of -40 F for 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The package specimen did not show any evidence of leakage or adverse effects as a result of exposure to either the high or low temperature tests.
1 RESULTS: The package passed the thermal tests.
2.6.6 Reduced and Increased Extemal Pressure Tests 71.71(c)(3)and(4)
Two holes were drilled into the lid of the test specimen to accommodate pressure fittings. The package was placed into a thermal test chamber and the temperature reduced to -20 F. A pressure / vacuum gage was attached to one fitting. A vacuum pump attached to the other pressure fitting was used to simulate an external over pressure of 20 PSIA by establishing 9.4 psia in the package. Applying 11.2 psig compressed air pressure to the second fitting simulated the decreased external pressure condition (3.5 psia).
Two initial tests under reduced and increased external conditions failed because of inadequate locking rings. The first test was run using lever latch locking rings which did not provide adequate closure. On the second trial, the bolted locking rings were for a larger diameter drum and did not provide adequate closure. On the third test, with proper locking rings, the specimen contained the pressure differentials for ten minutes.
RESULTS: The package passed the reduced and increased external pressure tests.
2.6.7 Free Dron Test 71.7)(c)(7)
The package specimen was preconditioned to -20 F and dropped onto a horizontal unyielding surface from a height of four feet at an angle of 45 onto its top edge and then again dropped from four feet height squarely from the horizontal onto its cylindrical side. The edge was dented from the edge drop but no loss of contents were noted.
A second drop test was conducted to verify that dropping the package onto the locking ring lug would not cause failure. These test drums were packaged with non-radioactive bales. Sand was added as an indicator of loss of contents during the drop. Gross container weights were 442 and 502 pounds. There was no loss of contents or structural integrity. A third drop test was conducted to determine if the sand present in the second test could act to cushion the waste contents and thereby-4 10 1

CertiGcate of Compliance Application for 40 Gallon Container Model No. 40G-A Rev.1 (06/30/93) invalidate the drop test. Two test drums were packaged with non-radioactive bales and scrap metal for a total container weight of 340 and 351 pounds. Bales were oriented in the drum parallel to the impact surface to provide the most severe potential for damage. The package specimens were preconditioned to -20*F and dropped onto a horizontal unyielding surface from a height of four feet at an angle of 45* onto the locking ring lug and then the second package was dropped from four feet height squarely from the horizontal onto its cylindrical side with the locking ring lug oriented downward. The edge and side were dented from the drop but no loss of contents were noted. There was no loss of contents or structural integrity.
RESULTS: The package passed thefree drop test.
2.6.8 No Continuous Venting The package does not incorporate any feature which would allow continuous venting during transport. Waste material generated in the decommissioning of the facility creates approximately 0.036 milliwatts of decay heat per gram of radioactive material. To alleviate concern regarding hydrogen generation and pressure buildup, if the drum is packaged more than ten days prior to shipment, the drum will be vented by opening the lid.
3 OUALITY ASSURANCE PROGRAM The package covered by this certiGcate will be used under the general Ucense provisions of 10 CFR 71.12. The two registered users, Nuclear Fuel Services, Inc (NFS) and Scientific Ecology Group, Inc. (SEG), already possess NRC-approved quality assurance programs as follows; NFS-Docket # 07100249 and SEG-Docket # 07100496.
4 OPERATING PROCEDURE 4.1 PURPOSE The purpose of this procedure is to provide the guidelines for the receipt, use and preparation for shipment of the 40 gallon package for LSA waste with greater than Type-A quantities of radioactivity. This package is only certified for isotope concentrations that do not exceed the limits for LSA radioactive materials. This procedure will be used for the preparation and shipment of this package.
