In addition, the designer should consider several desirable objectives, which

the decontamination technology and methodology should meet:

reduction of cost,

reduction of generated waste volumes,

increase in productivity,

achievement of high decontamination factors,

capability of remote operator (if required), and

capability for mobile operation.

During the dismantlement phase, various methodologies and site-specific

requirements should be considered. The dismantlement is influenced by the

type of contamination present, the level of contamination (whether remote

operation is required), the facility size, and by the design features (glovebox,

canyon, reactor, etc.) included in the facility.

If the designer determines that advanced, cutting-edge technology is required,

operational controls should minimize spread of contaminants, generation of

secondary wastes, and generation of mixed waste, and it should have ALARA

features regarding worker exposures.

The area of material disposition will also require significant input by the D&D

plan designer. Material disposition includes activities to recycle valuable

materials for reuse and disposal of material that cannot be reused cost

effectively and in a manner that protects human health and the environment.

Various treatment methodologies are needed to support material disposition

and should be selected by the designer to meet material disposition goals.

These methodologies include the following:

chemical treatments,

stabilization,

packaging,
