24.

BY-PRODUCT MATERIAL. Any radioactive material (except special nuclear material) yielded in

or made radioactive by exposure to the radiation incident to the process of producing or utilizing

special nuclear material, and the tailings or wastes produced by the extraction or concentration of

uranium or thorium from any ore processed primarily for its source material content. [AEA]

Where relevant to a particular NEPA document, add:

By-product material is exempt from regulation under the Resource Conservation and Recovery Act.

However, the exemption applies only to the actual radionuclides dispersed or suspended in the waste

substance. Any nonradioactive hazardous waste component of the waste is subject to regulation under

the Resource Conservation and Recovery Act. [Derived from DOE 5820.2A, 10 CFR 962]

25.

CALCINE. To heat a solid to a high temperature below the melting point in order to drive off volatile

constituents, convert the material to a powder, or cause other changes, such as oxidation or reduction.

Originally referred specifically to the heating of calcium carbonate (i.e., limestone) to drive off carbon

dioxide gas and form calcium oxide (i.e., quicklime).

Note: Calcine may also be used as a noun, referring to the product of calcining. [Derived from

AHD, MW, and UW]

26.

CANDIDATE SPECIES. Plants and animals native to the United States for which the U.S. Fish and

Wildlife Service or the National Marine Fisheries Service has sufficient information on biological

vulnerability and threats to justify proposing to add them to the threatened and endangered species

list, but cannot do so immediately because other species have a higher priority for listing. The Services

determine the relative listing priority of candidate taxa in accordance with general listing priority

guidelines published in the Federal Register. (See endangered species and threatened species.)

27.

CANISTER. A general term for a container, usually cylindrical, used in handling, storage,

transportation, or disposal of waste.

28.

CANYON. A large heavily shielded concrete building containing a remotely operated plutonium or

uranium processing facility.

29.

CAPABLE FAULT. In general, "capable fault" means a geologic fault along which it is mechanically

feasible for sudden slip (i.e., earth motion) to occur. [Derived from Bolt]

Nuclear Regulatory Commission reactor siting regulations define a capable fault as a fault which has

exhibited one or more of the following characteristics:

(1) Movement at or near the ground surface at least once within the past 35,000 years or movement

of a recurring nature within the past 500,000 years.

(2) Macro-seismicity instrumentally determined with records of sufficient precision to demonstrate a

direct relationship with the fault.
