Attachment 1
Special Nuclear Material Exemption Certification Attachment
Special Nuclear Material Waste Acceptance Criteria
(To be completed by the Waste Generator)

If SNM (Special Nuclear Material) is present in the waste, this certification form must be completed and signed certifying the following conditions. This form and all required information must be attached to the waste profile form and the waste manifest.

1. Please check at least one of the foliowing that applies to the waste stream:

Table 1. Maximum allowable concentrations of SNM in individual waste containers.

-	Radionuclide	Maximum Concentration (g SNM/g waste)	Measurement Uncertainty (g SNM/g waste)
	U-235¹	9.891 E-4	15%
	U-235²	6.18 E-4	15%
	U-233	4.732 E-4	15%
	Pu-239	2.795 E-4	15%
	Pu-241	2 15 E-4	15%

¹ Less than 10 percent enrichment
² Greater than 10 percent enrichment

2. Please certify that the following conditions have been satisfied by checking each box:

a. Concentrations of SNM in individual waste containers do not exceed the applicable values listed in the above table and SNM isotope concentrations listed in Table 1.

b. The SNM is homogeneously distributed throughout the waste or the SNM concentrations in any contiguous mass of 450 kilograms (990 Ibs) do not exceed on average the specified limits. (Based on process knowledge or testing).

c. Waste does not contain "pure forms" of chemicals containing carbon, fluorine, magnesium, or bismuth in bulk quantities (e.g., a pallet of drums, a B-2s box). By "pure forms," it is meant that mixtures of the above elements such as magnesium oxide, magnesium carbonate, magnesium fluoride, bismuth oxide, etc. do not contain other elements. (Based on process knowledge or testing).

d. Waste does not contain total quantities of beryllium, hydrogenous material enriched in deuterium, or graphite above one-tenth of one percent of the total weight of the waste. (Based on process knowledge, physical observations, or testing).

e. Waste packages do not contain highly soluble forms of uranium or plutonium greater than 350 grams of uranium-235 or 200 grams of uranium-233 or plutonium. If the waste contains mixtures of plutonium, U-233 and U-235, the waste meets the sum of the fractions rule. Highly soluble forms of uranium (and plutonium) include, but are not limited to: uranium sulfate, uranyl acetate, uranyl chloride, uranyl formate, uranyl fluoride, uranyl nitrate, uranyl potassium carbonate, and uranyl sulfate. (Based on process knowledge or testing).

3. Please indicate that the following information is attached to the Radioactive Waste Profile Record by checking each box. (Note: Only the two-page SNM Exemption Certification form needs to be included with each manifest, unless an alternative sampling plan was approved at the pre- acceptance stage).

a. Provide a description of how the waste was generated, list the physical forms in the waste, and identify the uranium chemical composition and other chemicals that may be present in the waste.

b. Provide a general description of how the waste was characterized (including the volumetric extent of the waste, and the number, location, type, and results of any analytical testing), the range of SNM concentrations, and the analytical results with error values used to develop the concentration ranges.

c. Describe the process by which the waste was generated showing that the spatial distribution of SNM must be uniform, or other information supporting spatial distribution.

d. Describe the methods to be used to determine the concentrations on the waste profile and manifests. These methods could include direct measurement and the use of scaling factors. Describe the uncertainty associated with sampling and testing used to obtain these concentrations.

4. Generator's certification of compliance with the SNM exemption: I certify that the information provided on this form is complete, true, and correct and is based on process knowledge, physical observations, or laboratory testing. I also certify that any supporting documentation and analytical results have been submitted to WCS.
