(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. [Derived from Suter, EPA RPD]

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.
