possibilities for disposal are:

Sanitary sewer: Disposal through the sanitary

sewer. This may be regulated by several

agencies, such as DOE, NRC, EPA, and State

and local water pollution control boards.

Their regulations will set concentration limits

and, perhaps, annual limits.

Evaporation: The water can be evaporated in

engineered evaporation systems.

Solidification: The water can be used to

make concrete for solidification of other

liquid wastes.

Decay: Water from a small-volume, high

concentration system could be transferred to

a large-volume, low concentration system

where it can decay safely.

Ion exchange resins and filters: These are

radionuclides such as Be-7, Na-22, Mn-54,

and Co-60.
