Notes

It may be desirable to dispose of water before the tritium

concentration becomes too high. Some 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 used to

remove impurities from recirculating cooling water

systems and can accumulate radionuclides such as Be-

7, Na-22, Mn-54, and Co-60.

Maintenance/modifications

Radioactive waste can be generated by maintenance and

modification of beamline components. Waste from this source

may include:

Compactables: Compactables such as rags,

anticontamination clothing, surface coverings, etc.

Tools, equipment, components: Items that are no

longer of use. These may consist of materials

contaminated by the transfer of activated radioactive

material to their surface or items that are

radioactivated from being in the beamline.
