Solid Waste Confinement Systems

DOE-HDBK-1132-99

A site diversion system for surface water runoff during operation of the

facility. (This system should not be required following site permanent

closure.)

Temporary protective covers (e.g., a tarpaulin) before the completion of

the natural in-place soil barrier over the low-level waste.

Revegetation of the overburden layer.

Other suitable and reliable means for minimizing water contact with low-

level waste.

Solid Waste Confinement Systems . The following provisions are typical for

an RSWF confinement system. The actual confinement system requirements

for a specific RSWF should be determined on a case-by-case basis.

In general, the primary confinement should be the radioactive solid waste

process system equipment and associated off-gas or vent systems during

the treatment stage of processing. In special cases, such as RSWF

where the processes or storage include corrosive or noxious materials,

the radioactive solid waste process or storage system should be totally

enclosed and provided with its own ventilation system and off-gas

cleanup system. In such cases, the radioactive solid waste process or

storage system should be treated as the primary confinement system.

Depending on the waste being processed and stored, the primary

confinement and secondary confinement should consist of a site-specific

engineered system of barriers (e.g., drums, liners, concrete casks).

Secondary confinement for radioactive solid waste during treatment

should consist of a process cell or building and its ventilation system;

secondary confinement for radioactive solid waste during interim storage

should be provided by a storage building or structure.
