Hazard Summary

The majority of solid waste is bagged out of gloveboxes through typical bagout ports, sealed

with tape in a second layer of plastic, and placed inside a hard plastic pail. The lid of this

pail is also sealed with a thin strand of tape, which serves as much to indicate tampering as it

does to prevent the lid from being removed. These pails are then temporarily stored in the

pre-assay storage room, which can accommodate up to 25 pails. After assay, up to 40 pails

can be stored in another room. Five pails can also be temporarily stored in the assay room.

The pails are eventually taken to the drum packaging room, where 20 pails can be

temporarily stored on a floor array awaiting drumming. This room has a ventilated waste

hut where operators in protective clothing remove individual waste bags from pails and place

them in a lined 55-gallon drum. Up to 10 filled and sealed drums can be stored in a floor

array in the drum packaging room, but normal practice is to take drums to the TRU-Waste

storage annex after they are sealed and assayed. Up to 320 drums can be stored on fire-

retardant coated pallets in the TRU-Waste storage annex.

Large glovebox waste, such as equipment that cannot be bagged out, is covered and placed

inside sealed wooden crates for immediate removal. Low-level solid waste generated outside

gloveboxes or in general maintenance is placed either in drums or in fire-retardant wooden

crates depending on its size. There are three authorized locations in the hallways of the

TRU-waste storage annex to temporarily hold a maximum of two wooden crates per location.
