CH-TRU Waste Content Codes
waste. Payload containers in the 100 Series are generated under a formal certification program.
Payload containers in the 200 Series are generated prior to site implementation of a formal
certification program. The second and third numbers of the three-digit code designate the
physical and chemical form of the waste. Table 4 lists the generic content codes that are used,
the waste type for each code, and a brief description of each content code.
- Content codes are further defined as subcodes by an alpha trailer after the three-digit code to
allow segregation of wastes that differ in one or more parameter(s). For example, the alpha
trailers of the subcodes LA 117A and LA 117B are used to differentiate between LANL metal
waste packaged within a maximum of four layers of plastic bags (LA 11 7A) and LANL metal
waste packaged within a single plastic bag (LA 117B).
A "numeric" shipping category notation was introduced in June 1999. Sites may continue to use the old
"alpha-numeric" shipping category designation. Cross correlation lists (alpha-numeric/numeric and
numeric/alpha-numeric) are provided in Tables 5 and 6. Definitions and examples of the two shipping
category notations are provided in Table 7.
As specified in the CH-TRAMPAC, sites have the option of taking credit for the use of dose-dependent
G values based on matrix depletion for certain wastes (i.e., Waste Material Type I1.1 and Waste Type III).
These dose-dependent G values are reflected in the "YYYY" (G value) portion of the numeric shipping
category and have no effect on the waste type ("XX") or resistance ("ZZZZ") portions of the numeric
shipping category. All shipping categories listed in Table 2 may be used with either the dose-dependent or
non-dose-dependent YYYY values, as applicable. Note: For waste described by an alpha-numeric shipping
category, the site must first convert the alpha-numeric shipping category to a numeric shipping category, and
then revise the shipping category to reflect the dose-dependent G value. A correlation of waste material
types, G values, and numeric shipping category notation, both with and without credit for matrix depletion,
is provided in the CH-TRAMPAC.
Table 8 is a list of acronyms and abbreviations used in this document.
Requests for new or revised content codes may be submitted to the WIPP CH-TRU Payload Engineer for
review and approval, provided all CH-TRAMPAC requirements are met.
The format for content codes is as follows:
- Content Code
- Content Description
- Storage Site (if applicable)
- Generating Site
- Waste Description
- Generating Source(s)
- Waste Form
- Waste Packaging
- Assay
- Free Liquids
- Explosives/Compressed Gases
- Pyrophorics
- Corrosives
- Chemical Compatibility
- Payload Container Venting and Aspiration
