RH-TRU Waste Content Codes [report]

Washington TRU Solutions
2007 unpublished
If a site implements the administrative controls outlined in the RH-TRAMPAC and Appendix 2.4 of the RH-TRU Payload Appendices, the decay heat or FGGR limits based on a 10-day shipping period (rather than the standard 60-day shipping period) may be used as specified in an approved content code. Requests for new or revised content codes may be submitted to the WIPP RH-TRU Payload Engineer for review and approval, provided all RH-TRAMPAC requirements are met. Each of these parameters is discussed

CONTENT CODE: Identifies the two-letter site abbreviation that designates the physical location of the waste and the three-digit code that designates the physical and chemical form of the waste. CONTENT DESCRIPTION: Identifies the physical form of the waste, describing whether it is inorganic or organic, solidified, or solid. GENERATING SITE: Provides the location of waste generation. STORAGE SITE: Provides the location of the waste, if the location is different than the generating site. If the generating site and storage site are the same, this section is not required to be included in the content code. WASTE DESCRIPTION: Provides basic information regarding the nature and/or main components of the waste. GENERATING SOURCE(S): Lists processes and/or buildings at each site that generate the waste in each content code. RH-TRUCON, Rev. 7, July 2007 DOE/WIPP 90-045 9 WASTE FORM: Provides more detailed information on the waste contents, how the waste is processed, and specific information about the constituents. This includes an estimate of the average waste density as packaged. WASTE PACKAGING: Describes, in detail, techniques necessary for waste packaging in a given content code. This includes the number and type of layers of confinement used in packaging waste, and the mechanism for bag, can, or container closure. In addition, this includes the size and shape of inner and outer waste containers, an estimate of the average void volume within each confinement layer, the number and type of filters (if present) in each confinement layer, and the number of waste containers per RH-TRU waste canister, as well as the type of RH-TRU waste canister to be used (i.e., fixed-lid or removable-lid canister). Default void volumes for standard layers of confinement are provided in Table 2 .5-2 of Appendix 2.5 of the RH-TRU Payload Appendices. METHODS FOR ISOTOPIC DETERMINATION: Describes the types of radioactive measurement techniques or other methods used to obtain fissile material content and decay heat values for a particular content code. Information on the radionuclide composition of the waste (ratios of isotopes/percentages by mass or activity) and date of determination must be provided by the site for the determination of decay heat limits. RESIDUAL LIQUIDS: Describes the procedures used to ensure that the limit imposed on residual liquids (<1% by volume) is met for each content code. EXPLOSIVES/COMPRESSED GASES: Identifies the methods used to preclude the presence of explosives or compressed gases. PYROPHORICS: Describes the controls in place to ensure that pyrophoric materials in the waste are not present in quantities greater than 1% by weight. CORROSIVES: Describes the controls in place to ensure that corrosive materials in the waste either are not present or are neutralized or immobilized prior to placement in a container. CHEMICAL COMPATIBILITY: Describes the controls in place to ensure chemical compatibility for the waste contents and the RH-TRU 72-B packaging. All chemicals/materials in the waste in quantities greater than 1% by weight for a specific content code are restricted to the list of allowable chemicals/materials (Table 4 .3-1 of the RH-TRAMPAC). The total quantity of trace chemicals/materials in the payload container not listed in Table 4 .3-1 of the RH-TRAMPAC is limited to 5% as specified in Section 4.3. CHEMICAL LIST: Lists the chemicals/materials that may be present in the content code in quantities greater than 1% (weight) (used in the chemical compatibility evaluation) and less than or equal to 1% (weight) and, additionally, may identify the predominant chemicals/materials or relevant quantities (% weight) of specific materials (used in the G value determination). G VALUE: Defines the G value (gas generation potential) for the content code based on the chemicals/materials present in the waste. ADDITIONAL CRITERIA: Provides details on how the waste qualifies for shipment by meeting additional transport requirements.
