contaminated with hazardous chemicals and are radioactive. Such debris could<br />

result from cleanup or construction work performed'`in contaminated areas. It<br />

is assumed that these wastes will have low levels of contamination and would<br />

be easily size reduced for compatibility with immobilization. Much of this<br />

waste will need to be dealt with on a case-by-case basis as it is generated in<br />

rela ively small quantities from various sources. This waste will add about<br />

59 m^ (2,100 ft3) each year of throughput to the WRAP 2A Facility.<br />

1.2.4 Feedstream 4: Noncompactible Solids<br />

Noncompactible solids will come from similar sources as compactible<br />

solids but will consist of hard debris, such als metal piping, ng, brick, concrete<br />

or glass. It will account for as much as 34 m (1,200 ft ) each year of<br />

throughput to WRAP 2A.<br />

immobilization process. These are generally small volume waste streams that<br />

will not be treated in the main process line at WRAP 2A. The subcategories<br />

are discussed in the following sections.<br />

1.2.5.1 Mercury/Mercury Contaminated Solids. This waste consists of<br />

elemental mercury and bulk contaminated solid wastes, such as fluorescent<br />

light bulbs, laboratory thermometers, manometers, and mercury absorbents.<br />

Elemental mercury will be treated in accordance with Best Demonstrated<br />

Achievable Technology (BDAT), which requires amalgamation. Bulk contaminated<br />

solids will be shredded and residual mercury metal removed as required by<br />

BDAT.<br />

1.2.5.2 Reactive Metals. This stream contains zirconium and beryllium, which<br />

are easily ignited or oxidized in air if the particle size is fine enough and<br />

an ignition source is available. It is assumed that 50 wt% of the total<br />

incoming feedstream must be deactivated by pretreatment before encapsulation;<br />

the rest will require no pretreatment before encapsulation. No distinction is<br />

made between zirconium or beryllium metals for treatment requirements. It is<br />

assumed that no other reactive metals, such as sodium, potassium, or calcium,<br />

are present in this feedstream. These react_ive metals would require entirely<br />

different treatment techniques because of their reactive properties.<br />

___L 2.5_3__Lead/Lead_Contaminated-Sol!ds.Th-ts-feedstream consists of le'ad<br />

and lead contaminated bulk solids. Elemental lead will be treated in<br />

accordance with BDAT, which requires macroencapsulation. Bulk contaminated<br />
