AMBIENT AIR. The general air in the area of interest (e.g., the general room

atmosphere), as distinct from a specific stream or volume of air that may have different

properties.

ANALYSIS. The use of methods and techniques of arranging data to: (a) assist in

23.

determining what additional data are required; (b) establish consistency, validity, and

logic; (c) establish necessary and sufficient events for causes; and (d) guide and support

inferences and judgements. [DOE G 225.1A-1]

24.

ANALYTICAL TREE. Graphical representation of an accident in a deductive approach

(general to specific). The structure resembles a tree - that is, narrow at the top with a

single event (accident), then branching out as the tree is developed, and identifying root

causes at the bottom branches. [DOE G 225.1A-1]

25.

ANNUAL LIMIT ON INTAKE (ALI). The derived limit for the amount of radioactive

material taken into the body of an adult worker by inhalation or ingestion in a year. ALI

is the smaller value of intake of a given radionuclide in a year by the reference man

(ICRP Publication 23) that would result in a committed effective dose equivalent of 5

rems (0.05 sievert) or a committed dose equivalent of 50 rems (0.5 sievert) to any

individual organ or tissue. ALI values for intake by ingestion and inhalation of selected

radionuclides are based on Table 1 of the U.S. Environmental Protection Agency's

Federal Guidance Report No. 11, Limiting Values of Radionuclide Intake and Air

Concentration and Dose Conversion Factors for Inhalation, Submersion, and Ingestion,

published September 1988. This document is available from the National Technical

Information Service, Springfield, VA. [10 CFR 835.2]

ANTICIPATED OPERATIONAL OCCURRENCE OR EVENT. An abnormal event

26.

that is expected to occur during the lifetime of the facility (e.g., small radioactive

materials spills, small fires). [DOE O 5480.30] [EH62dd1]

APPOINTING OFFICIAL. A designated authority responsible for assigning Accident

27.

Investigation Board Type A and Type B investigations, with responsibilities as

prescribed in Paragraph 5d of DOE O 225.1A. [DOE O 225.1A] [DOE G 225.1A-1]

28.

APPROVED STORAGE CONTAINER. A container that is fabricated from

noncombustible materials); that satisfies container integrity criteria developed from the

safety analysis for the particular form(s) of stored material under normal storage

conditions, design basis fire and other design basis accident conditions; and that is

approved for its intended use by the responsible DOE operating contractor and the

responsible DOE field organization. [DOE O 6430.1A]
