(3) A structural relationship to a capable fault according to characteristics (1) or (2) such that

movement on one could be reasonably expected to be accompanied by movement on the other.

[10 CFR 100, Appendix A]

30. CASK. A heavily shielded container used to store or ship radioactive materials. [NRC

Glossary]

31. CHARACTERISTIC WASTE. Solid waste that is classified as hazardous waste because it

exhibits any of the following properties or "characteristics": ignitability, corrosivity, reactivity,

or toxicity, as described in 40 CFR 261.20 through 40 CFR 261.24. (See hazardous waste,

solid waste, and waste characterization.) [Derived from 40 CFR 261]

32. CHRONIC EXPOSURE. A continuous or intermittent exposure of an organism to a stressor

(e.g., a toxic substance or ionizing radiation) over an extended period of time or significant

fraction (often 10% or more) of the life span of the organism. Generally, chronic exposure is

considered to produce only effects that can be observed some time following initial exposure.

These may include impaired reproduction or growth, genetic effects, and other effects such as

cancer, pre-cancerous lesions, benign tumors, cataracts, skin changes, and congenital defects.

33. CLADDING. The outer metal jacket of a nuclear fuel element or target. It prevents fuel

corrosion and retains fission products during reactor operation and subsequent storage, as well

as providing structural support. Zirconium alloys, stainless steel, and aluminum are common

cladding materials.

In general, a metal coating bonded onto another metal.

[Derived from NRC Glossary, TM]

34. CLASS I AREA. A specifically designated area where the degradation of air quality is

stringently restricted (e.g., many national parks, wilderness areas). (See prevention of

significant deterioration.) [Derived from 40 CFR 51.166(e)]

35. CLOSURE. Refers to the deactivation and stabilization of a waste treatment, storage, or

disposal unit (such as a waste treatment tank, waste storage building, or landfill) or hazardous

materials storage unit (such as an underground storage tank). For storage units, closure

typically includes removal of all residues, contaminated system components, and contaminated

soil. For disposal units (i.e., where waste is left in place), closure typically includes site

stabilization and emplacement of caps or other barriers. Specific requirements for the closure

process are found in the regulations applicable to many types of waste management units and

hazardous material storage facilities.

Provide a document-specific definition if appropriate.
