Inventory of Hazardous Materials
The hazard identification process resulted in identifying process operation locations within the WHB and
the Underground disposal horizon for which an inventory of radiological material could be identified.
The anticipated inventory was determined based on material form, location, and quantity associated with
the process of receipt, handling, and disposal of RH TRU waste.
These process operation locations include:
1. Waste Handling Building
Ç RH Bay
Ç Cask Unloading Room (CUR)
Ç Hot Cell
Ç Transfer Cell
Ç Facility Cask Loading Room
Ç Conveyance Loading Room
2. Underground Horizon
Ç Waste Shaft Station
Ç Disposal Panel
Table 5.1-1 summarizes the maximum RH TRU waste canister inventory by facility process location.
The radiological and non-radiological 72-B waste canister contents and the 10-160B cask contents are
characterized in Section 5.1.2. The bounding radiological and non-radiological hazardous material
inventory for each process location may be obtained by multiplying the number of 72-B waste canisters
or the number of 10-160B casks by the maximum contents derived in Section 5.1.2.
5.1.2 RH Waste Characterization
This section describes the methodology used in the development of RH 72-B waste canister and 10-160B
cask contents (radioactive/chemical content) to be disposed of at the WIPP. A description of 72-B waste
canisters, 10-160B casks, types, volumes, radioactive and non-radioactive constituents, and discussions
on content development are included for use in the hazards and accident analysis.
72-B waste canisters considered for this analysis are standard DOT Type A (or equivalent) canisters
(maximum gross weight of 8,000 lb (3628.7 kg). The design of the canister is discussed in detail in
Section 4.2.
The 10-160B cask meets the certification requirements for DOT Type B shipping containers (10 CFR
71.71-73) and has a maximum gross weight of 72,000 lb. The maximum total weight of the contents of a
10-160B cask is 14,500 lbs. including any shoring, waste drums, and optional insert. 13 The 55-gal drums
in the 10-160B cask meet the certification requirements for DOT Type A shipping containers (49 CFR
178.350).
