RH-TRAMPAC Document Rev. 0, June 2006PYROPHORICS: Describes the controls in place to ensure that pyrophoric materials in thewaste are not present in quantities greater than 1% by weight.CORROSIVES: Describes the controls in place to ensure that corrosive materials in the wasteeither are not present or are neutralized or immobilized prior to placement in a container.CHEMICAL COMPATIBILITY: Describes the controls in place to ensure chemicalcompatibility for the waste contents and the RH-TRU 72-B packaging. All chemicals/materialsin the waste in quantities greater than 1% by weight for a specific content code are restricted tothe list of allowable chemicals/materials (Table 4.3-1). The total quantity of tracechemicals/materials in the payload container is limited to 5% as specified in Section 4.3.CHEMICAL LIST: Lists the chemicals/materials that may be present in the content code inquantities greater than 1% (weight) (used in the chemical compatibility evaluation) and less thanor equal to 1% (weight) and, additionally, identifies the predominant chemicals/materials orrelevant 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 thechemicals/materials present in the waste.ADDITIONAL CRITERIA: Provides details on how the waste qualifies for shipment bymeeting additional transport requirements (e.g., venting containers).MAXIMUM ALLOWABLE FLAMMABLE GAS GENERATION RATES: Specifies theflammable gas generation rate (FGGR) limits for the content code. The FGGR limits arecalculated using information from the Waste Packaging parameter above.MAXIMUM ALLOWABLE DECAY HEAT LIMITS: Specifies the decay heat limits for thecontent code. The decay heat limits are calculated using information from the Waste Form,Waste Packaging, Methods for Isotopic Determination, and G Value parameters above. Decayheat limits based on dose-dependent G values are also specified, as applicable.1.5.2 Use and ApprovalAll containers must have a content code approved by the Waste Isolation Pilot Plant (WIPP)RH-TRU Payload Engineer to be eligible for shipment. Any site requiring the transportation ofRH-TRU waste in the RH-TRU 72-B that is not described in an approved content code mustrequest the revision or addition of a content code by submitting a request in writing to the WIPPRH-TRU Payload Engineer.The WIPP RH-TRU Payload Engineer has the authority to approve a content code request only ifcompliance with the transportation requirements of the RH-TRAMPAC can be demonstrated.Any submittal not meeting the requirements of the RH-TRAMPAC shall not be approved forinclusion in the RH-TRUCON document or be used as the basis for a shipment in the RH-TRU72-B. The WIPP RH-TRU Payload Engineer does not have the authority to change thetransportation requirements for the RH-TRU 72-B as specified in the RH-TRAMPAC withoutapproval from the U.S. Nuclear Regulatory Commission (NRC).The process for requesting a content code addition or revision is as follows:1. The site prepares in writing a request containing sufficient information to satisfy all of thenecessary elements identified in Section 1.5.1. If the request is for a content code1.5-2
RH-TRAMPAC Document Rev. 0, June 2006revision, only the revised elements require preparation and documentation. The site shallensure that the information submitted in the form of a content code addition or revisionaccurately describes the waste and waste generating processes based on site knowledge.2. The site submits the request (e.g., draft content code or revised content code elements) inwriting to the WIPP RH-TRU Payload Engineer for review.3. Under the direction of the WIPP RH-TRU Payload Engineer, the submittal shall bereviewed for completeness and satisfactory demonstration of compliance with alltransportation requirements of the RH-TRAMPAC. As part of this review, the WIPPRH-TRU Payload Engineer responsibilities may include a review to ensure that theinformation required for each of the previously identified elements (Section 1.5.1) iscomplete, compliance with the list of allowable chemicals/materials pursuant toSection 4.3 is evaluated, and confinement layer release rates and G values areappropriately applied in the calculation of flammable gas generation limits pursuant tothe methodology referenced in Section 5.1. The WIPP RH-TRU Payload Engineer shallnot approve any submittal that does not demonstrate compliance with everytransportation requirement for the RH-TRU 72-B.4. Upon completion of the review, the WIPP RH-TRU Payload Engineer shall send formalwritten notification to the site indicating the status of the request. If the request is denied,the WIPP RH-TRU Payload Engineer shall indicate in the notification the reason why therequest was not accepted and shall identify which elements of the submittal areincomplete or out of compliance.5. If the request is approved, a site may begin using the new or revised content code onceofficial notification is received from the WIPP RH-TRU Payload Engineer. Sites maynot use proposed content code additions or revisions to make shipments in the RH-TRU72-B prior to receipt of written notification from the WIPP RH-TRU Payload Engineer.6. The WIPP RH-TRU Payload Engineer shall record all approved content code additions orrevisions in the RH-TRUCON document. The current revision of the RH-TRUCONdocument shall be available to sites.1.5-3
